The trunking units or end caps are simply inserted into the lower housing of the joint block. Once the upper part of the joint block or end cap is fitted, a secure connection is established by simply tightening the 4 screws. Figure 1-3 Establishing a safe connection Tap-off units Tap-off units are available in four different sizes to connect the loads and also with various components fitted, e.g. such as plugs, fuses, miniature circuit breakers or combinations of the aforementioned. Figure 1-4 Tap-off unit BD01 system Ancillary equipment units offer additional space for decentral function expansions. Thus, automation and control components can be installed directly on the busbar. SIVACON 8PS - Planning with SIVACON 8PS 16 Planning Manual, 11/2016, A5E01541101-04 System overview 1.2 BD01 system Fixing and mounting The BD01 busbar is installed edgewise, with the tap-off points on the side using fixing brackets on the wall, ceiling or non-fixed installation. The mounting is implemented on the connection points using a universal fixing bracket. The system can also be fitted flat with the tap-off points pointing downwards. This reduces the required fixing interval by half. Figure 1-5 Fixing the BD01 system Fire protection If the busbar trunking system is routed through a fire wall or ceiling, it must have fire protection. Compliant with site requirements, Siemens offers fire protection class S90. (EI90 available soon) Ex-works equipment: External fire protection in the form of a kit for on-site mounting Mineral mortar or fire protection mastic to seal the joints between busbar trunking system and component must be provided by the customer. Figure 1-6 Fire protection BD01-S90 The approval documentation for Germany can be ordered separately: Approval kit BD01-S90-ZUL-D (approval certificate, wall signage and declaration of compliance) SIVACON 8PS - Planning with SIVACON 8PS Planning Manual, 11/2016, A5E01541101-04 17 System overview 1.3 Networked busbar trunking systems for industrial and building applications 1.3 Networked busbar trunking systems for industrial and building applications The advantages of busbar trunking systems The busbar trunking system has its advantages in the transport, distribution as well as switching and protection of electrical energy. Integration of automation and building systems engineering into the Siemens busbar trunking systems results in further advantages and also increases the flexibility of the busbar trunking system. The combination of standard tap-off units with standard ancillary equipment units guarantees enhancement in efficiency with the design, installation and operation.

End user requirements have to be matched with the technical capabilities of the manufacturer. This planning manual will provide assistance as you plan and design the following busbar trunking systems from 160 A to 6300 A: BD2 LD LI LR Description of the individual systems Each system has a dedicated chapter describing its technical characteristics and areas of application. Illustrations of the individual busbar trunking system elements also appear. All significant information relevant to the planning process is given particular emphasis and explained in detail. Further information You will find advice to help you to develop a ready-to-use planning solution under "Further information". These include specific dimensioning principles and detailed information about topics such as fireproof barriers and functional endurance. Siemens can offer a range of services and engineering tools to assist you in drafting your specification. For an overview and explanation of functions and features, please see Tools and services (Page 307). SIVACON 8PS - Planning with SIVACON 8PS Planning Manual, 11/2016, A5E01541101-04 19 Planning principles 2.2 Busbar trunking system planning 2.2 Busbar trunking system planning 2.2.1 Principles of busbar trunking system planning Decision-making criteria affecting the creation of the power supply concept When drafting a planning concept for a power supply, in addition to the applicable standards and regulations, you also need to clarify and address issues of cost and technology. Accordingly, when dimensioning and selecting electrical equipment such as distribution boards and transformers, rather than focussing on them individually, you need to aim to optimise their performance as part of a combined system. All components have to be dimensioned sufficiently for loads both in rated operation and in the event of a malfunction. Furthermore, you must take the following important issues into consideration when drafting a power supply concept: Building type, use and design (e.g. high rise, low rise or number of storeys) Determination of load centres, identification of possible supply routes and locations for transformers and main distribution boards Calculation of the building's effective installed loads according to specific area loads as appropriate for the building's use Planning authority regulations and requirements Requirements set out by the utility company Requirements to be met by power supply concepts Planning will never produce just a single option for a solution. Rather, you will need to assess a number of possible options on the basis of issues relating to technology and cost. The following requirements are major factors: Simple and transparent planning Long service life High availability Low fire load Flexible adaptation to changes in the building SIVACON 8PS - Planning with SIVACON 8PS 20 Planning Manual, 11/2016, A5E01541101-04 Planning principles 2.2 Busbar trunking system planning The solution: Siemens busbar trunking systems In most applications, these requirements can easily be solved by using suitable busbar trunking systems. It is for this reason that busbar trunking systems are increasingly being preferred to cable trunking by engineering consultants charged with designing systems for power transmission and distribution. Siemens offers busbar trunking systems from 40 to 6300 A: The BD01 busbar trunking system from 40 to 160 A for supplying power to shopfloors with tap-offs up to 63 A The BD2 system from 160 to 1250 A for supplying power to medium-sized consumers in building and industrial applications The ventilated LD system for supplying power to consumers with medium power requirements in industrial applications The LI sandwich system for power distribution to consumers with high power requirements in building applications The LR cast resin system for power transmission under extreme ambient conditions (IP68) Figure 2-1 Siemens busbar trunking systems SIVACON 8PS - Planning with SIVACON 8PS Planning Manual, 11/2016, A5E01541101-04 21 Planning principles 2.2 Busbar trunking system planning 2.2.2 Different types of busbar trunking systems and their functional scope Requirements of the power supply Specific requirements of power supplies and their individual components are typical of modern production facilities and in building technology today. This is particularly true of automated facilities. The ability to retrofit new equipment or modify existing resources without interrupting active production is not only important for the continuous provision of the electrical power supply. It is also a vital requirement for production facilities operating on a multiple shift basis. Increased safety and complex systems require a power distribution system which is able to respond to all requirements associated with costs and technology. The BD01, BD2, LD, LI and LR busbar trunking systems are type-tested low-voltage switchgear assemblies in accordance with IEC / EN 61439-1 and -6. The BD01, BD2 and LD systems consist of busbars, internal bar fixings, an external enclosure, fixing and connection accessories. The LI sandwich system and the LR cast resin system consist of busbars, fixing and connection accessories and an insulating foil, along with an aluminium enclosure (LI ) or an enclosure made from epoxy resin (LR). Figure 2-2 BD2 trunking unit with tap-off unit Power transmission Components of the busbar trunking system transmit power between transformers and low voltage power distribution systems and from the main distribution board to the service distribution board. Trunking units without tap-off points are used for the power transmission. In addition to the standard lengths, customers can select any lengths to meet their particular building requirements. SIVACON 8PS - Planning with SIVACON 8PS 22 Planning Manual, 11/2016, A5E01541101-04 Planning principles 2.2 Busbar trunking system planning Power distribution The main application of busbar trunking systems is power distribution. Current can't be taken from just a single point which is permanently installed such as a cable installation. Current tap-off units can be moved to any position within the entire system. To tap power at any given point simply requires positioning a tap-off unit at that location on the busbar. The result is a flexible distribution system for decentralised power supply to a particular line or area. Tap-off points can be mounted on one or both sides of straight trunking units. Depending on the requirements of the particular application, busbar trunking units with tapoff units for a rated current of 1250 A from a single tap-off point are available for tapping off power and connecting loads. The tap-off units can be equipped with fuses, fuse-switches, miniature circuit breakers or circuit breakers as desired. To be able to change the tap-off units without disconnecting the busbar trunking run, the following requirements apply: The PE contact on the tap-off unit leads during installation and lags during removal. The parts which are live during installation, removal or connection have complete protection against direct contact (degree of protection IP2x). Installation requires phasing to be correct. The tap-off unit must be isolated during installation and removal.

Network topology Transparent (line topology with load feeders connected in series via tap-off units) Significant cable cluster at feeding point due to point-to-point power supply to loads from central power distribution system Protective devices for loads In the tap-off unit: facilitating direct and immediately traceable assignment to load locally. Centrally in the distribution board: this means that assignment to the load cannot be verified directly. You have to rely on the cable and load being labelled correctly. Space requirements Low High, since correspondingly large distribution boards are needed. Laying criteria (clustering, laying method, current carrying capacity, etc.) have to be taken into account Retrofitting in the event of changes to load feeders Highly flexible thanks to tap-off points in the trunking units and large number of different tap-off units Time-consuming and expensive. Additional cables need to be laid from the distribution board to the load.

Power distribution can be planned precisely on the basis of total connected load and the type and number of loads. Planning tools such as SIMARIS design provide assistance. The line topology with load feeders arranged at regular intervals ensures transparency. All applications can be implemented quickly and compactly with standardised sizes. In a cable trunking system, new loads have to On busbar trunking systems, tap-off units in be connected via an additional sub-distributionthe vicinity of loads ensure local transparency. board; this costs both time and money. Increased safety due to high short-circuit rating and minimum fire load. Advanced safety - both in respect of short-circuit rating and where fire load is concerned. BD2A 250 busbar trunking systems, for example, have a fire load of just 1.32 kWh/m, whereas comparable cable trunking systems (NYY 4 x 95 / 50 mm2) are rated at 5.19 kWh/m. The busbars are also halogen-free. Siemens busbar trunking systems feature high short-circuit rating. Furthermore, troubleshooting is made easier thanks to local load short-circuit protection.

The short-circuit rating of the LD, LI and LR busbar trunking systems is usually higher than the values for the transformer's sustained and peak shortcircuit currents. However, this only applies if just a single transformer is used for the lowvoltage supply. Higher short-circuit values are possible on ring or meshed networks or if transformers are connected in parallel in a low-voltage switchgear assembly. Such scenarios must therefore be given special consideration. Please refer to the technical data for the busbar trunking systems in question for specific data about short-circuit ratings.

Designed for applications involving flexible power supplies and power distribution for consumers in industrial and commercial environments, it can also be used to transmit power from one supply point to another. In addition, the BD2 busbar trunking system can be used as a rising main busbar in high rise buildings. 3.2 System components 3.2.1 Preliminary remark for specifications The BD2 busbar trunking systems are to be offered as type-tested low-voltage switchgear assemblies in accordance with IEC / EN 61439-1 and -6. The brand offered represents a complete system consisting of system modules, including elements for connection to the distribution boards such as brackets, straight trunking units, e.g. Z connectors, T connectors, and flexible junction units. Trunking units with tap-off openings can be equipped with coded tap-off units. Tap-off units are protected against incorrect mounting. Depending on the type, the isolation of the tap-off units during removal is assured by a compulsory sequence of operations or by cautionary instructions. If necessary, it is possible to equip the busbar trunking system with an asbestos-free fire barrier which conforms in the case of BD2C to the fire resistance class S120 and in the case of BD2A to S90 or S120 (EI90 and EI120 available soon). The trunking unit's steel enclosure is made of moulded steel profiles to permit large fixing distances between suspension points. The enclosure is painted in a light grey colour (RAL 7035). The external dimensions may not exceed 68 x 167 mm up to 400 A or 126 x 167 mm up to 1250 A. The connection of the individual systemmodules is implemented with state-of-the-art quick connection terminals with integral compensation for expansion. The system is protected against phase inversion. A mechanical, electrical and maintenance-free connection between two busbar trunking system elements can be established quickly and safely using conventional tools. The conductors are made of aluminium or copper. The aluminium and copper conductors must be nickel-plated and tinned along their entire length. The fire load should not exceed the value stated in the technical specifications. Expansion compensation must be integrated into eachtrunking unit. Busbar trunking units should be able to be mounted both horizontally and vertically. Junction units may not be used to connect cables.. Flexible junction unit are permissible as system modules of the busbar trunking system. The following declarations of conformity must be included with the offer: EN ISO 9001 QA certification Certificates verifying - That the fire barrier has been tested and approved - That functional endurance has been tested and approved SIVACON 8PS - Planning with SIVACON 8PS 36 Planning Manual, 11/2016, A5E01541101-04 Planning with BD2 3.2 System components The general preliminary remarks are followed by a detailed description of the system as appropriate for technical requirements: Technical data for BD2 busbar trunking systems BD2-...

You can find more detailed information in the "Technical specifications". 2) Please delete as appropriate. Note The innovative design and construction of the BD2 busbar trunking system means that additional compensation units to compensate busbar expansion are not required. Prevailing length expansion caused by current heat is compensated in the quick connection terminal. Furthermore, regardless of mounting position and degree of protection, the BD2 busbar trunking system can always be loaded at 100 % of rated current. This only has to be reduced in the case of pure power transmission in the edgewise mounting position (to 0.9 x Ie).

The incoming supply can be set up as an end feed or a centre feed. 3.2.5.1 End feeder units Common features All end feeder units have the following common features: Cables can be fed in from the front end. Units with cable compartments support cable entry from the side. In the case of multi-core conductor entry, a sectional entry flange with cable sleeves and cable propping bar is standard; in the case of single-core conductor entry, an aluminium plate is standard. The cables are connected using lugs and bolts. The bolts are supplied with the unit. When connecting 5-conductor cables you will need to remove the bridge between PE and N which will have been fitted prior to delivery. The phasing can be changed locally.

The sectional entry flange with integrated strain relief can be converted to these positions. Aluminium cable entry plates for single-core cables as an alternative option. The cables are connected using lugs and bolts. When connecting 5conductor cables you will need to remove the bridge between PE and N which will have been fitted prior to delivery. Figure 3-8 Centre feed Version Type 160 ... 400 A BD2.-400-ME 630 ... 1000 A BD2.-1000-ME 160 ... 400 A BD2.-400-ME-MBAL 630 ... 1000 A BD2.-1000-ME-MBAL Important planning information: A centre feed might be the best option for the distribution of high powers with small busbar cross sections. It is mounted in the centre of a trunking run between two trunking units. A single power supply cable provides power to the left-hand and right-hand trunking runs simultaneously. This means, for example, that a 1000 A centre feed can feed in 2000 A. In such cases you need to pay particular attention to the busbar system's overload and shortcircuit protection. You will need to provide protective measures in the following instances: If short-circuit protection is not provided by the upstream protective device and/or If the overload is not set by the type and number of loads. There are two possible protective measures: 1. Use a centre feed unit with one coupling unit on the left of the incoming feeder and another on the right. The coupling unit is fitted with a protective device (fuse or circuit breaker) providing short-circuit and overload protection. 2. Use two end feeder units located in the centre of the trunking run. The two supply lines are fused separately in the distribution system.

To adapt the busbar trunking system to the actual load, the busbar cross section can be reduced and protected against short circuits and overloads with a coupling unit. Coupling units can be fitted with load disconnect switches up to 630 A or circuit-breakers up to 1250 A as appropriate for the application concerned. The maximum installation length in the busbar trunking run is 1500 mm. The dimensions of the coupling unit must not exceed 1250 x 500 x 500 mm (W x H x D).

The tap-off units used must be compatible with the values required by the equipment as far as their short-circuit rating and rated voltage are concerned. If the tap-off unit is not compatible with the rated voltage, a unit with appropriate internal components must be selected. Higher short-circuit currents must be limited by means of upstream protection devices (e.g. circuit breakers).

The system offers a high short-circuit rating and is particularly suited for the connection of transformers to low-voltage main distribution boards and sub-distribution boards. In applications where high powers are required, conventional systems frequently require the use of parallel cables. The LD system offers optimal power distribution for both horizontal and vertical busbar runs. Coded plug-in tap-off units up to 1250 A that meet extremely high safety standards are available for this purpose. 4.2 System components 4.2.1 Preliminary technical descriptions for specifications The busbar trunking systems are to be offered as type-tested low-voltage switchgear assemblies in accordance with IEC / EN 61439-1 and -6, and as sheet-steel-enclosed readyto-use distribution boards. The distribution systems must be suitable forpower transmission, e.g. between transformer and low-voltage main distribution boards, as well as for power distribution providing a supply of power to an entire area. The brand offered must be a complete system consisting of system modules, including transformers and elements for connection to the distribution boards, as well as such as brackets, straight trunking units and junction units. All components should be available both in straight and offset versions. Trunking units with tap-off openings should be able to be equipped with coded tap-off units. Tap-off units are protected against incorrect mounting. Depending on the type, the isolation of the tap-off units during removal is assured by a compulsory sequence of operations or by cautionary instructions. If required, the busbar trunking system should be capable of being equipped with asbestosfree fire barriers which comply with fire resistance class S120 (EI120 available soon), and which have been certified by the local or government authority responsible for building standards. The trunking unit's steel enclosure is made of moulded steel profiles to permit large fixing distances between suspension points. The enclosure is galvanised and painted in a light grey colour (RAL 7035). The external dimensions may not exceed 180 x 180 (240) mm. The individual system modules are connected by hanging a hook from a bolt and tightening a state-of-the-art maintenance-free single-bolt clamp. The conductor between two system units should not be connected with screws. The conductor material is made of aluminium or of copper if the rated current requires. The aluminium conductor must be nickel-plated and tinned, and the copper conductor must be tinned and provided with an additional insulating layer of epoxy-resin. The fire load must not exceed the value specified in the technical data. Junction units with flexible connections or cable connections are not permitted.

SIVACON 8PS - Planning with SIVACON 8PS Planning Manual, 11/2016, A5E01541101-04 107 Planning with LD 4.2 System components Important planning information The nominal mounting position of the busbar trunking system is horizontal and edgewise for the busbars. In very rare cases, due to a specific trunking run or the option of connecting tap-off units on the side, the busbars might have to be laid flat. The resulting increase in the internal heat rise of the system necessitates a reduction in rated current. The same applies to vertical height rises > 1.3 m (see the table in the chapter "Type code (Page 108)"). The LD busbar trunking system is a ventilated system. When the degree of protection is increased from IP34 to IP54 (enclosed system), the rated current must be derated as specified in the tables in the next chapter. 4.2.2 Type code Definition of the required system using the type code The basic components of the LD system are determined using a type code. The type is specified and selected on the basis of rated current, conductor material, system type and degree of protection. The resulting type code enables the required system to be precisely defined. SIVACON 8PS - Planning with SIVACON 8PS 108 Planning Manual, 11/2016, A5E01541101-04 Planning with LD 4.2 System components Selection example A rated current of 2500 A is calculated for a project. Aluminium conductors shall be used. A 4-pole system also has to be used. The cross section of the protective conductor needs to be equal to the cross section of the phase conductor. The required degree of protection is IP34. The mounting position is horizontal, edgewise, without height rises. Use of the above table results in the selection of the following type: LDA 5423 SIVACON 8PS - Planning with SIVACON 8PS Planning Manual, 11/2016, A5E01541101-04 109 Planning with LD 4.2 System components 4.2.3 Sizes, conductor configurations and structure of the busbar package The LD busbar trunking system is available in two sizes.

Figure 4-2 Sectional drawing of a 7-bar system LD busbar systems are available with aluminium (LDA....) and also copper (LDC....) conductor materials. Due to the conductors' special surface finishing, trunking units with different conductor materials can be combined. In addition to tinning, aluminium bars are also coated with a layer of nickel.

To compensate this expansion in length, you need to include expansion compensation units at defined intervals when planning your horizontal installation. With trunking units for vertical installation, the expansion compensation is integrated. When planning horizontal busbar runs, please remember: * A straight trunking run without expansion compensation between two junction units must not exceed 10 m in length. * A straight trunking run between a junction unit and the end cap must not exceed 25 m in length. In the case of longer trunking run lengths, planning provision has to be made accordingly for expansion compensation units. SIVACON 8PS - Planning with SIVACON 8PS Planning Manual, 11/2016, A5E01541101-04 113 Planning with LD 4.2 System components Tap-off points Tap-off points are only possible on straight trunking units (both standard lengths and optional lengths possible). Options are: Tap-off points at the TOP: ...-AD Tap-off points at the BOTTOM: ...-ADU Tap-off points at the TOP and BOTTOM: ...-ADO+U With a trunking unit with a tap-off point at the TOP and BOTTOM, only one tap-off unit can be used at a time. The required distance between tap-off points is 1 m. The required type should be determined during engineering, based on the mounting position of the busbar. In the case of optional trunking units with tap-off point, a minimum clearance of 0.6 m is required between the end of the busbar and a tap-off point. A coding bracket is located on both sides of a tap-off point. This guarantees noninterchangeability and correct phasing sequence installation of the tap-off units.

The connection unit is built into the distribution board and serves as an interface to the copper connections of the distribution system. Rated currents The maximum rated currents are listed in the chapter "Technical specifications (Page 128)". The temperature limit of busbars coated with insulating materials is 135 C. You can find possible conductor cross-sections for the copper connections in the chapter "Technical specifications (Page 128)". Installation of the busbar connection unit The busbar connection unit in the distribution board must be copper-plated by the board manufacturer or in compliance with that manufacturer's specifications. The board manufacturer must ensure that the required short-circuit strength is achieved and the permissible temperature limit of the busbar connection unit for non-Siemens distribution boards is not exceeded.

These tap-offs are implemented in the form of tap-off units with fuse switchdisconnectors or with circuit breakers. There are basically two types of tap-off unit: With fuse switch disconnector With circuit breaker Figure 4-11 Tap-off unit with fuse switch disconnector and trunking unit with tap-off point Early-make PE/PEN The current tap in the tap-off unit is implemented as an early-make (mounting) or late-break (removal) PE/PEN conductor contact. In a 4-conductor system, this is ensured by a longer PEN bar at the contact mechanism. In a 5-conductor system the PE connection is established via grinding contacts on the coding brackets. Anti-rotation feature and non-interchangeability The coding brackets on the tap-off unit and on the trunking unit's tap-off point (lock-and-key principle) ensure: Non-interchangeability and correct assignment of 4 or 5-pole tap-off units to the associated LD systems Anti-rotation feature to prevent incorrect mounting of the tap-off units on the tap-off points SIVACON 8PS - Planning with SIVACON 8PS 122 Planning Manual, 11/2016, A5E01541101-04 Planning with LD 4.2 System components 4.2.11.2 Tap-off units with fuse switch disconnector Rated currents Tap-off units 125 A, 2 x 125 A, 250 A, 400 A and 630 A are available for selection. Depending on the current level, LV HRC fuses size NH 00, NH 1, NH 2 or NH 3 are used. The compact dimensions mean that only one enclosure size is required for all rated current ranges. Operator control The tap-off units with fuse switch disconnector are operated by hand using a swivel mechanism. Degree of protection The standard degree of protection is IP30. IP54 degree of protection can be provided as an option. Degree of protection IP30 Degree of protection IP54 Cable compartment / cable entry A bolted connection is used for cables with cross sections up to 2 x 240 mm2.

The busbars can be connected: From above From below (on request) This enables a flexible arrangement. The link between the busbar trunking system and the SIVACON S8 distribution systems ensures high short-circuit strength backed up by type testing and a high level of reliability as regards power transmission.

The connection unit is built into the distribution board and serves as an interface to the copper connections of the distribution system. Versions Depending on system type, a total of eight different conductor configurations are available for selection. The rated currents up to a maximum of 6300 A correspond to the specifications in the chapter "Technical specifications (Page 197)". In accordance with DIN EN 61439-1 and DIN EN 61439-6, the temperature limit in distribution systems in the event of heat rise must not be exceeded by the current heat. The temperature limit of busbars sheathed with insulating materials is 135 C. You can find the required conductor cross-sections for the copper connections in the chapter "Technical specifications (Page 197)". Installation of the busbar connection unit The busbar connection unit in the distribution board must be copper-plated by the board manufacturer or in compliance with that manufacturer's specifications. The board manufacturer must ensure that the required short-circuit strength is achieved and the permissible temperature limit of the busbar connection unit for non-Siemens distribution boards is not exceeded.

As a general rule, they are equipped with: Fuse bases, fuse switch disconnectors, switch disconnectors with fuses or circuit breakers with handle or motorised operating mechanism Bolts for cable connection Conductor configurations in acc. with type LI...-6.: For conductor systems with insulated PE conductor, the tap-off units are supplied with the addition of a separate PE connection. Tap-off units Tap-off via tap-off point Anti-rotation feature prevents incorrect mounting IP20 touch protection whilst the unit is being connected to the tap-off point Note Hot plugging In accordance with DIN EN 50110-1 (VDE 0105-1), national regulations must be observed. Country-specific regulations may prohibit plugging when the busbar run is not switched off and energized with electrical power. Cable entry You can insert the cables optionally from the side or the front. Integrated flange with cable grommets facilitates multi-core cable entry. Aluminium plates are used for single-core cable entry; you have to fit these with cable glands locally. Blanking plates are attached at the side for delivery. Safety during operation To open the tap-off units, you must switch the breaker off either by actuation of the handle or at the motorised operating mechanism of the breaker. Once this is done, the cable connection area is no longer energized. The part of the contact device in the front of the tapoff unit is "finger-safe". Implementing the tap-offs Tap-offs are required for different amperages depending on the size and type of loads involved. These are implemented by means of plug-in tap-off units up to 1250 A.

To calculate the voltage drop in the distance d between the start of a tap and the start of the busbar system, proceed as follows: k = (2 x n + 1 - n x d/L)/(2 x n) Voltage drop diagrams The following diagrams illustrate the voltage drop on the BD2, LD, LI and LR systems taking into account the final heating resistances (in accordance with 61439-6) with a load distribution factor - k = 1 for LD and LR - k = 0.5 for BD2 and LI at rated current load. (In the case of a different current diversity factor, the value of the curve must be multiplied by the appropriate distribution factor).

Fuses and circuit breakers are available for use as protective devices. When selecting protective devices, the level of the expected short-circuit currents, selectivity requirements or operating and signalling functions are also factors for consideration. When deciding to provide short-circuit protection using fuses and circuit breakers, you must not exceed the specified short-circuit ratings of the busbar trunking systems. Whether a current limiting protective device is required and what short-circuit breaking capacity the protective device must have depend on the level of expected short-circuit current. The table below offers an overview of the circuit-breakers which are able to provide shortcircuit and overload protection (400 V and 50 Hz) for the corresponding busbar system. The following applies: I"k Icc Icu I''k Icc Icu Table 7- 1 = anticipated short-circuit current at installation location = conditional rated short-circuit current of the trunking run = rated short-circuit breaking capacity of the circuit breaker Circuit-breakers which are able to provide short-circuit and overload protection (400 V and 50 Hz) for the corresponding busbar system1) Type Rated Circuit breakers Rated curwith normal shortrent switching capacity circuit current 1) In A Icu Icc Circuit breakers Rated with strong shortswitching capacity circuit current 2) Icu Icc Circuit breakers with high switching capacity Rated shortcircuit current 1) Icu Icc kA kA kA kA kA kA BD2A(C)-160 160 3VL27 16-1... 40 20 3VL27 16-2... 70 20 3VL27 16-3... 100 20 BD2A(C)-250 250 3VL37 25-1... 40 40 3VL37 25-2... 70 50 3VL37 25-3... 100 50 BD2A(C)-400 400 3VL47 40-1... 45 45 3VL47 40-2... 70 45 3VL47 40-3... 100 45 BD2A(C)-630 630 3VL57 63-1DC36 45 45 3VL57 63-2DC36 70 70 3VL57 63-3DC36 100 100 BD2A(C)-800 800 3VL57 80-1SE36 - 50 3VL57 80-2SE36 70 70 3VL57 80-3SE36 100 100 BD2A(C)-1000 1000 3VL77 10-1SE36 - 50 3VL77 10-2SE36 70 60 3VL77 10-3SE36 100 60 BD2C-1250 1250 3VL77 12-1SE36 - 50 3VL77 12-2SE36 70 60 3VL77 12-3SE36 100 60 1) The tripping characteristic of the protective device must be selected as appropriate for the short-circuit rating of the busbar systems, the type of system, the type and number of loads, as well as in line with country-specific regulations and type series. This table contains only a brief overview of BD2 on the use of circuit breakers for protection against short-circuit and overload, and it is intended only as a recommendation. We always recommend that you carry out a calculation using the SIMARIS design network tool to determine the appropriate protection. Please contact our TIP specialists for this purpose. 2) The values for the conditional rated short-circuit current Icc apply for the busbar trunking systems without taking account of the tap-off units.

You can find the impedance values for calculating the loop impedances of a busbar trunking system in the following chapters: For the BD2 busbar trunking system in the chapter titled "Technical specifications (Page 62)" For the LD busbar trunking system in the chapter "Technical specifications (Page 128)" For the LI busbar trunking system in the chapter "Technical specifications (Page 197)" For the LR busbar trunking system in the chapter "Technical specifications (Page 252)" Calculating the loop impedance of all contributory equipment in a system (incoming power supply, transformers, distribution boards, cable runs, etc.) takes a great deal of time and effort. In this regard, planning time and effort can be reduced significantly by using a dimensioning program such as SIMARIS design which stores the necessary data for most common electrical equipment in a database. 7.1.4 Degrees of protection for busbar trunking systems Use in areas at risk of fire In areas at risk of fire, in accordance with European standard HD 384.4.482 S1, increased requirements are placed on the degree of protection to be afforded for electrical equipment. In the event of a fire risk due to the nature of the materials being processed or stored, the minimum degree of protection must be equivalent to IP5X if there is a potential for dust accumulation. If dust is not to be expected, national regulations shall apply accordingly. The risk prevention arm of the association of German insurers sets out the following requirements: In the event of a fire risk due to dust and/or fibres: IP5X degree of protection In the event of a fire risk due to other readily flammable solid foreign bodies with a diameter of 1 mm or more: IP4X degree of protection SIVACON 8PS busbar trunking systems meet these requirements. They are therefore suitable for such applications.

"Finger-safe" touch protection only applies to the actuator in the actuating direction. Measured from the central point, a clearance with a radius of r = 30 mm must be maintained between the actuator and touch-hazardous parts.

Examples of these types of building include hospitals and public buildings. In this regard, DIN VDE 0100-560 relating to buildings and structures for public use and DIN VDE 0100-710 (previously DIN VDE 0107) relating to medical locations, and/or legal requirements specify that the electrical installations in such buildings must maintain functional endurance for specific lengths of time even in the event of a fire. This requirement affects the following equipment in particular: Fire alarm systems Systems for alerting and providing instructions to visitors and employees Emergency lighting Passenger lifts with evacuation circuits that assure functional performance for at least 30 minutes in the incoming cable area under full fire conditions Water pressure boosting systems for the supply of extinguishing water Ventilating systems of safety stairwells, fire department lifts and machine rooms where functioning must be guaranteed for at least 90 minutes. To be able to offer the required functional endurance for busbar trunking systems, we have, for example (in some cases working together with Promat), had the BD2, LD, LI and LR busbar trunking systems tested successfully at the Materials Testing Institute in Braunschweig and Leipzig in Germany. During fire testing the busbar trunking systems concerned (housed in Promatect plate casings of varying thicknesses) were subjected in this respect to an external fire load in compliance with the standard temperature curve (STC) to evaluate functional endurance to DIN 4102-12.

Accordingly, neither fire nor fumes are permitted to spread from one floor or fire area to another. The BD01, BD2, LD, LI and LR busbar trunking systems can be equipped with fireproof barriers. Fireproof barriers are generally subject to the device standard IEC / EN 61439-6 and national regulations, and these can differ from each other. For this reason, we recommend that you contact your SIEMENS representative in the planning phase. The systems meet the requirements for proving fire resistance duration as per the fire resistance class specifications in ISO 834-1 in accordance with IEC / EN 61439-6. Permissible surface temperature on components (on the opposite side to the fire) max. 180K above the starting temperature Area on fire: Fire in accordance with standard temperature curve DIN 4102, Sheet 2 or DIN EN 1363-1 Permissible temperature increase of escaping air max. 140C Flammable gases must not be allowed to escape. No fumes likely to impair rescue attempts must be allowed to escape Figure 7-8 Conditions for busbar trunking systems SIVACON 8PS - Planning with SIVACON 8PS Planning Manual, 11/2016, A5E01541101-04 285 Further information about planning 7.4 Fireproof barrier 7.4.2 Versions Unlike cable trunking, the busbar trunking systems are supplied ex-works with a fireproof barrier. The fireproofing consists of an inner and outer barrier or an outer barrier only depending on the busbar trunking system. The fireproof barriers are compliant with fire resistance classes S60, S90 and S120 in accordance with DIN 4102-9 dependent upon version and type (EI60, EI90 and EI120 available soon). The fireproof barrier can be installed in the busbar trunking system at the factory (BD2, LD), added on site (BD01, LI, LR), or omitted completely (LR). Please note the section "Special conditions for the German market" in this regard. The type of installation is determined by the structure of the busbar trunking system and the required fire resistance class, as you can see from the overview below (the figures ignore the minimum clearances between the fireproof barrier and the wall, and the fireproof mortar): Without external fireproof barrier, in the centre of the wall/ceiling Without external fireproof barrier, in the centre of the wall/ceiling With external fireproof barrier on the wall/ceiling BD2A with inner fire protection S90 BD2A / BD2C: S120 BD01: S90 (Wall thickness 35 cm) (Wall thickness < 35 cm) (Fire protection installed on both sides) BD2A with inner fire protection S120 LR: S901) LR: S1201) BD01: S90 LD: S120 LI: EI90; EI120 Busbar system Outer fire barrier Examples (Wall thickness 35 cm) 1) Fire protection from the LR system is installed on-site after sealing the wall/ceiling with fillers.

Special conditions for the German market: The versions for fire barriers described here were created on the basis of tests passed in accordance with DIN 4102 Part 9 or EN 1366-3. In Germany, fireproof barriers must possess general planning authority approval or a European technical approval. These are issued by the German Institute for Civil Engineering in Berlin. All divergences from the approval must be clarified with the product manager for the purpose of applying to the respective regional building authority for agreement in individual cases if necessary. Fire safety tests have been carried out successfully for the installation of fireproof barriers in stud walls for the BD01, BD2, LD and LI systems. Please contact the relevant product manager for more detailed information about designs and approvals.

SIVACON 8PS - Planning with SIVACON 8PS 300 Planning Manual, 11/2016, A5E01541101-04 Further information about planning 7.6 Magnetic fields 7.6 Magnetic fields General information Due to their physical characteristics, busbars designed for power distribution and transmission generate pulsating electromagnetic fields in their vicinity with a fundamental frequency of 50 Hz. These magnetic fields can impair the ability of sensitive equipment such as computers or metering instruments to function in full working order. Limits EMC directives and the associated standards do not set out requirements or recommendations for the planning of busbar trunking systems. DIN VDE 0100-710 can be consulted in relation to busbar trunking systems used in hospitals. DIN VDE 0100-710 defines limits for line frequency magnetic fields in hospitals. For example, at 50 Hz, the magnetic induction around a patient's bed must not exceed the following values: B= 2 x 10-7 tesla for EEG B = 4 x 10-7 tesla for ECG The limit for inductive interference between multi-core cables and lines in a high voltage installation (conductor cross section > 185 mm2) and the patient beds to be protected is safely undershot if the minimum clearance of 9 m recommended in DIN VDE 0100-710 is complied with. When using busbars, this clearance can generally be reduced, since the busbar systems are designed to effectively reduce the magnetic interference fields in the local vicinity. Magnetic field measurements However, in order to facilitate evaluation of the busbars to be used in the planning phase, extensive magnetic field measurements have been taken in accordance with EN 61439-6. The magnetic field emissions of the busbar systems were measured on a straight trunking run that was 9.0 m long. With the busbars under a balanced rated current load, the magnetic fields were measures in eight directions at intervals of 0.1 m and up to a clearance of 1 m.

Sprinkler systems are automatic fire extinguishing systems. They are designed to detect the outbreak of fire at an early stage and extinguish it as quickly as possible. Once activated for the purpose of extinguishing fire, such systems usually run for at least 30 minutes. The BD2, LD and LI busbar trunking systems have been subjected to a sprinkler test. In the absence of a binding standard, the tests were carried out based on a test structure reflecting practical application (see diagram). SIVACON 8PS - Planning with SIVACON 8PS Planning Manual, 11/2016, A5E01541101-04 305 Further information about planning 7.7 Sprinkler test Test results BD2 and LI All mounting positions of the BD2 and LI busbar trunking systems were tested for water resistance in degree of protection IP54 on the basis of the national risk prevention guidelines for sprinkler systems issued in Germany. Insulation resistance measurements were taken before and after the 90-minute sprinkling period and a high-voltage test was carried out in accordance with IEC / EN 61439-6 . The equipment passed the test, proving that the busbar system can be put back into operation immediately and without delay once the sprinkler system has run its course. LD The LD busbar system with degree of protection IP34 and the associated tap-off units with degree of protection IP54 were sprinkled with both horizontal and vertical trunking runs with a 3/4" umbrella sprinkler and a 1/2" flat spray sprinkler at a water pressure of 6 bar. In order to be able to assess electrical performance during testing, insulation resistance measurements were taken during the course of the test. No operational failures occurred. Even when subject to extreme water loads such as those associated with sprinkler systems, the LD busbar system is able to remain in full working order. This operational reliability is made possible on the one hand by the generous creepages and clearances and on the other by the fact that water can drain away unhindered.
