AL 9 ... AE 110, AL..Z... and TAL 9 ... TAE 110
3-pole Contactors
d.c. Operated
Application
AL... and AE... contactors, as well as TAL... and TAE... versions, are mainly used for controlling 3-phase motors and more generally for controlling
power circuits up to 690 V a.c. (1000 V a.c. for AE... and TAE... contactors) or 220 / 440 V d.c.
Description
3-pole contactors of the block type design.
The AL... contactors are fitted with low consumption d.c. coils:
– AL 9 ... AL 16 contactors: 3 W (pull-in and holding)
– AL 26 ... AL 40 contactors: 3.5 W (pull-in and holding)
– AL 9Z ... AL 16Z contactors: with very low consumption d.c. coil 2.4 W (pull-in and holding)
Contactors are thus suitable for a direct control by PLC transistor outputs, without the use of an interface relay.
The TAL... version offers a large coil voltage range.
The AE... contactors are fitted with standard double-winding d.c. coils.
The TAE... version offers a large coil voltage range.
●AE 50 ... AE 110, TAE 50 ... TAE 110
Add-on lagging contact (factory mounted) for insertion of the"holding" winding.

AF 50 ... AF 110 3-pole Contactors
Electronic Coil Interface
a.c. / d.c. Operated - Wide Voltage Range
Application
AF 50 ... AF 110 contactors are mainly used for controlling 3-phase motors and generally for controlling power circuits up to 690 V a.c. and 220 V d.c.
The contactors can also be used for many other applications such as bypass, capacitor switching, lighting, d.c. power circuits...
The AF... contactors are fitted with an electronic coil interface which accepts a wide control voltage range, on a.c. 50/60 Hz or d.c. supplies. The same
contactor can accept various supply voltages according to the different countries where the electrical equipment will be installed, or some fluctuation
in the control voltage due to the local supply or network.
The AF... contactors are also fully suitable for operation in a.c. or d.c. control circuit liable to voltage interruptions or voltage dip risks.
Description
The AF 50 ... AF 110 3-pole contactors are of the block type design.
●Main poles and auxiliary contact blocks
–3 main poles,
–front and side mounted add-on auxiliary contact blocks.
●Electronic control:
The contactors are fitted with an electronic interface that very precisely controls the voltage to the coil. The electronic control circuit always works
using d.c. current through the coil and in a.c. operation the current is rectified before being applied to the coil. To achieve the levels of the currents
required for making and holding respectively, the voltage is pulsed across the coil with the aid of a transistor. The pulsing also implies that the current
in the coil can be optimally regulated all the time relatively independently of the voltage level. The function is controlled by a specific integrated circuit
developed by ABB.
Advantages
–Wide voltage range, e.g. 100 ... 250 V a.c. and d.c.,
–Can manage large voltage variations,
–Reduced power consumption,
–Very distinct closing and opening,
–Noise free,
–Can withstand voltage interruptions or voltage dips in the control supply (< 20 ms).
●Accessories: a wide range of accessories is available.
The accessories provided for the A 50 ... A 110 contactors can be used for the AF 50 ... AF 110 types.
AF... contactors specific design (see A... contactors for general design).

Electronic Coil Interface
a.c. / d.c. Operated - Wide Voltage Range
Application
AF 145 ... AF 1650 contactors are mainly used for controlling 3-phase motors and generally for controlling power circuits up to 690 V a.c. / 1000 V a.c.
or 220 V d.c. / 600 V d.c.
The contactors can also be used for many other applications such as bypass, capacitor switching, lighting, d.c. power circuits...
The AF... contactors are fitted with an electronic coil interface which accepts a wide control voltage range, on a.c. 50/60 Hz or d.c. supplies. The same
contactor can accept various supply voltages according to the different countries where the electrical equipment will be installed, or some fluctuation
in the control voltage due to the local supply or network.
The AF... contactors are also fully suitable for operation in a.c. or d.c. control circuit liable to voltage interruptions or voltage dip risks.
Description
The AF 145 ... AF 1650 3-pole contactors are of the block type design.
●Main poles and auxiliary contact blocks
– 3 main poles,
– 1 N.O. and 1 N.C. auxiliary contact block (fitted on the left side).
A maximum of 4 auxiliary contact blocks can be fitted on each contactor.
●Electronic control:
The contactors are fitted with an electronic interface that very precisely controls the voltage to the coil. The electronic control circuit always works
using d.c. current through the coil and in a.c. operation the current is rectified before being applied to the coil. To achieve the levels of the currents
required for making and holding respectively, the voltage is pulsed across the coil with the aid of a transistor. The pulsing also implies that the current
in the coil can be optimally regulated all the time relatively independently of the voltage level. The function is controlled by a specific integrated circuit
developed by ABB.
Advantages
–Wide voltage range, e.g. 100 ... 250 V a.c. and d.c.,
–Can manage large voltage variations,
–Reduced power consumption,
–Very distinct closing and opening,
–Noise free,
–Can withstand voltage interruptions or voltage dips in the control supply (< 20 ms).
●Control inputs
The large sizes AF 400 ... AF 1650 are equipped with low voltage inputs for control, for example by a PLC.
●Accessories: a wide range of accessories is available.

Contactors for Capacitor Switching
AC-6b Utilization Category according to IEC 60947-4-1
Capacitor Transient Conditions
In Low Voltage industrial installations, capacitors are mainly used for reactive energy correction (raising the power factor). When these capacitors
are energized, overcurrents of high amplitude and high frequencies (3 to 15 kHz) occur during the transient period (1 to 2 ms).
The amplitude of these current peaks, also known as "inrush current peaks", depends on the following factors:
● The network inductances.
● The transformer power and short-circuit voltage.
● The type of power factor correction.
There are 2 types of power factor correction: fixed or automatic.
Fixed power factor correction consists of inserting, in parallel on
the network, a capacitor bank whose total pow er is provided by the
assembly of capacitors of identical or different ratings.
The bank is energized by a contactor that simultaneously supplies
all the capacitors (a single step).
The inrush current peak, in the case of fixed correction, can reach
30 times the nominal current of the capacitor bank.
Single-step capacitor bank scheme
Use the A/AF... contactor ranges.
An automatic power factor correction system, on the other hand,
consists of several capacitor banks of identical or different ratings
(several steps), energiz ed separately according to the value of the
power factor to be corrected.
An electronic device automatically determines the power of the steps
to be energized and activates the relevant contactors.
The inrush current peak, in the case of automatic correction, de-
pends on the power of the steps already on duty, and can reach
100 times the nominal current of the step to be energized.
Multi-step capacitor bank scheme
Use the UA... or UA..RA contactor ranges.
Steady State Condition Data
The presence of harmonics and the network's voltage tolerance lead to a current, estimated to be 1.3 times the nominal current In of the capacitor,
permanently circulating in the circuit.
Taking into account the manufacturing tolerances, the exact power of a capacitor can reach 1.15 times its nominal power.
Standard IEC 60831-1 Edition 2002 specifies that the capacitor must therefore have a maximum thermal current IT of:
IT = 1.3 x 1.15 x In = 1.5 x In
Consequences for the Contactors
To avoid malfunctions (welding of main poles, abnormal temperature rise, etc.), contactors f or capacitor bank switching m ust be sized to withstand:
● A permanent current that can reach 1.5 times the nominal current of the capacitor bank.
● The short but high peak current on pole closing (maximum permissible peak current Î ).
Contactor Selection Tool for Capacitor Switching
In a given application, if the user does not know the value of the inrush current peak,
this value can be approximately calculated using the formulas given on the Application
Guide "Contactors for Capacitor Switching".
Alternatively by the CAPCAL Selection Tool, available on the ABB Website:
www.abb.com/lowvoltage
right menu: "Support"
search: "Online Product Selection Tools"
select: "Contactors: AC-6b Capacitor Switching"
This program allows the calculation of these peaks and gives the references of the ABB
contactors according to the installation specifications. This calculation is valid for one
or several capacitor banks.

ABB offers 3 contactor versions according to the value of the inrush current peak and the power of the capacitor bank.
UA..RA Contactors for Capacitor Switching (UA 16..RA to UA 110..RA) with insertion of damping resistors.
The insertion of damping resistors protects the contactor and the capacitor from the highest inrush currents.
UA... Contactors for Capacitor Switching (UA 16 to UA 110)
Maximum permissible peak current Î < 100 times the nominal rms current of the switched capacitor.
A... and AF... Standard Contactors (A 12 to A 300 and AF 50 to AF 750)

complete with their damping resistors and must be used without additional inductances (see table below).
The capacitors must be discharged (maximum residual voltage at terminals ≤ 50 V) before being re-energized when the contactors are making.
Their electrical durability is 250 000 operating cycles for Ue < 500 V and 100 000 operating cycles for 500 V < Ue < 690 V.
Description
The UA..RA contactors are fitted with a special front mounted block, which ensures the serial insertion of 3 damping resistors into the circuit to limit
the current peak on energization of the capacitor bank. Their connection also ensures capacitor precharging in order to limit the second current peak
occurring upon making of the main poles.
Operating principle
The front-mounted block mechanism of the UA..RA contactors ensures:
●early making of the auxiliary "PA" poles with respect to the main "PP" poles
●automatic return to the open position of the auxiliary "PA" poles after the main poles are closed.
When the coil is energized, the early making auxiliary poles connect the capacitor to the network via the set of 3 resistors. The damping resistors
attenuate the first current peak and the second inrush current when the main contacts begin to make. Once the main poles are in the closed position,
the auxiliary poles automatically break.
When the coil is de-energized, the main poles break ensuring the breaking of the capacitor bank.
The contactor can then begin a new cycle.
The insertion of resistors allows to damp the highest current peak of the capacitor when switching on, whatever its level.

GA 75, GAE 75 Contactors for d.c. Switching
Application
GA 75 and GAE 75 contactors are designed for d.c. circuit switching.
Arc suppression is more difficult in d.c. than in a.c. To choose a contactor, it is necessary to know the current and voltage to be broken as well as
the L/R time constant of the power circuit to be controlled.
For your information, here are some typical time constant values:
DC-1: non inductive loads such as resistance furnaces: ............ L/R ~ 1 ms,
DC-3: shunt motors: .................................................................... L/R ~ 2 ms,
DC-5: series motors: ................................................................... L/R ~ 7.5 ms.
Remark: the addition of a resistor in parallel with an inductive winding makes arc suppression easier.

Connection Diagrams
In d.c. circuits, the source to earth (or frame) connection mode is an important element.
Three modes are mainly used:
A – insulated source, i.e. unearthed (or not connected to the frame),
B – source earthed via its central point,
C – source earthed via one of its outer poles.
Modes A and B do not impose any constraints with regard to the distribution of the contactor poles between the
two source / load connecting branches. Mode C requirements are therefore suitable for modes A and B.
For mode C, all the poles necessary for breaking must be installed in series between the load and the
unearthed (also not connected to the frame) source polarity.
We recommend this solution for all connection modes.
The above provisions relate to power circuit switching, the SCPD (Short-Circuit Protection Device) must comply
with protection rules.

AM... Magnetically Latched Contactors
d.c. Operated
Application
These contactors provide a safety function in those circuits where standard contactors would drop out in the
event of a faulty control circuit supply voltage, i.e. excessive voltage drops, control circuit voltage failures.
They also provide an energy saving function in those circuits where contactors are used for an uninterrupted
duty, i.e. distribution or current carrying duty.
This type of contactor is particularly suitable for industrial processes where voltage sags have heavy
consequences and is totally immune to voltage dips.
Description
The AM... magnetically latched contactors are very similar in construction and dimensions to the A... standard
contactors of equal rating. Only the electro-magnet and coil have a specific design in order to achieve the
latching and de-latching operations.
The operating coil is built with 3 connecting terminals and 2 windings which, when energized, create two
magnetic fields of opposite strength.
The coil windings must be energized from a d.c. supply, polarity (+ and -) must be observed.
Operation
–Contactor closing i.e. latching via "B" circuit. The contactor is held in closed position due to the circuit
remanency.
–Contactor opening, i.e. de-latching via "A" circuit.
–On closing and opening the coil windings are automatically controlled and briefly energized through
"B" (N.C.) and "A" (N.O.) auxiliary contacts.
The AM... contactors have two resting positions, closed position and open position and are delivered in
closed position.
Changeover from one position to another is achieved by impulses on the coil with a minimum duration of
100 ms.
Coil operating limits: 0.85 ... 1.1 Uc
Technical Data
Same technical data as for the AE 50, AE 75 contactors with the exception of:
–coil consumption: 210 W on latching, and 45 W on de-latching.
–mounting positions: position 5 is prohibited (see "Technical Data" for mounting position diagram).

Star-Delta Starting
of Three-Phase Asynchronous Motors
General
Star-delta starting is the most common method to reduce the starting current of a motor. This system can be used on all the squirrel cage motors,
which are normally used in delta connection.
In this type of starting, it is recommended to choose motors having high starting torque i.e. much higher than the resistive torque in order to reach
sufficient high speed when the motor is connected in star.
Star-delta starting
Technical Data
When starting:
– inrush current is reduced to a third of direct starting current,
– motor torque is reduced to a third or even less of direct starting torque.
Transient current is generated when switching from star to delta connection.
Utilization
During the initial starting phase ("star" connection), the resistive torque of
the driven load must remain, irrespective of speed, less than the "star"
motor torque until "star-delta" switching occurs.
This starting mode is therefore ideal for machines having low starting
torque such as:
– pumps,
– centrifugal compressors,
– wood-working machines, etc.
In order to prevent a high current peak, at least 85 % of nominal
speed must be reached before switching from star to delta.
Precautions
Motor nominal voltage in delta connection must be equal to that of the mains.
Example:
A motor for 400 V star-delta starting must be designed for 400 V in "delta"
connection. Its usual designation is "400 V / 690 V motor". The motor must
be constructed with 6 terminal windings.
Sequence
Starting is a three-stage process:
1st stage - "Star" connection
Press the "On" button on the control circuit to close the KM2 "star" contactor. The KM1 "line" contactor then closes and the motor starts. Countdown
of programmed starting time (normally 6 to 10 s) then begins.
2nd stage - "Star" to "Delta" switching
When the programmed starting time is over, the KM2 "star" contactor opens.
3rd stage - "Delta" connection
A transition time (or dwelling time) of 50 ms is fixed between opening of the "star" contactor and closing of the "delta" contactor by the use of TE5S
timer. This prevents short circuit between "star" and "delta".
Note: When AF... contactor types are used as delta and star contactors or an A... contactor as star contactor with an AF... contactor as delta contactor, the use of a timer including a dwelling time
(or transition time) e.g. TE5S is not recommended. A timer set for the starting duration in star connection is enough. An electrical interlock between star and delta is mandatory such as VE 5 or through
auxiliary contacts.
Furthermore, in open transition, the current interruption may reach up to 95 ms: it shall be checked that this duration is compatible with the application i.e. mainly if the decreasing in rotation speed
is acceptable during the starting phase.

Control of Three-Phase Slip-Ring Motors
Contactor Selection
General
Three kinds of contactors are used to control three-phase slip-ring motors: the stator contactor, the acceleration contactor(s) and the rotor short-
circuit contactor. Refer to the diagram opposite.
The selection tables below concern complete smooth starting, excluding specific cases, such as: intermittent operation, regenerative current,
controlled slipping, etc. for which you need to consult our specialised departments.
The starting and breaking technical data for slip-ring motors are defined in standard IEC 60947-4-1 in the AC-2 utilization category.
Operating cycle
The load factor is defined by the equation: L. F. (%) = x 100
Cycle time (Operating cycle + Rest cycle)
Stator Contactor
Closing of the starting current, conditioned by the value of the rotor resistances: it may reach 1.5 to 4 times rated motor operational current.
Breaking of the rated operational current, or of the starting current, with possible regenerative current.
The following table gives the permissible values of the Ie / AC-2 rated operational stator current, as a function of load factor.
Temperature of 55 °C maximum near the contactor.

Acceleration Contactors
The sizing of these contactors is based on the AC-1 rated
operational current (see "Technical Data") that we recall
below for the maximum ambient temperature of 55 °C.
Delta connection of these contactors is considered
(reduce currents by 35% if star connection is used).
The table opposite lists the factors to be applied to the
AC-1 current of the contactors in order to obtain the
permissible limit value of the motor rated operational rotor
current. This table takes into account the number of cycles
an hour (without inching) and the current flow time per cycle,
in the contactor.

Example of a Three-Stroke Starter
–The first stroke corresponds to energisation of the
motor by the stator contactor: all the resistances are
operational in the rotor circuit.
–At the second stroke, the acceleration contactor
short-circuits the first resistance stack.
–At the third stroke, the rotor short-circuit contactor
is activated by eliminating the last resistance stack,
thus completing the starting period.

General
An autotransformer starter allows to start a
squirel cage motor with a reduced starting
current due to the reduced voltage within the
accelerating duration.
At the contrary of the Star-Delta wiring, this
autotransformer starting method needs three
wires and three terminals on the motor.
At the starting period, the motor is wired to the
autotransformer taps: the Star Contactor "KM3"
and the Autotransformer Contactor "KM2" are
closed, the motor is under reduced voltage.
Consequently, the torque is reduced as the
square of the applied voltage. The
autotransformers are generally equipped of
three taps at each phase in order to adapt the
starting parameters to the field requirements.
When the motor reaches 80 ... 95% of its
nominal speed, the Star Contactor opens. Then,
the Line Contactor "KM1" is making and the
Autotransformer Contactor is opening. This
starting process is done without any network
interruption.

Lighting Circuit Switching
Contactor Selection
General
Contactor selection criteria for control of lighting circuits are as follows:
–type, power rating and number of lamps,
–connection mode,
–current values on closing and in steady state,
–power factor,
–presence or not of correction capacitors.
Lighting circuits
In a given circuit, the number and power rating of lamps are defined and cannot result in overload. Only short-circuit protection has to be provided.
gG fuses or modular circuit-breakers will be chosen for this purpose.
The lamps have very specific technical data, according to their construction type.
–Incandescent lamps have a very high current on closing: more than 15 times nominal current.
They do not introduce a large phase displacement between current and voltage.
–Fluorescent tubes are equipped with a ballast whose purpose is two-fold: contribute to ignition and limit current to nominal value once steady state
is reached. This ballast is a reactor that considerably lowers the power factor. It may or may not be compensated.
Individual compensation Serial compensation in dual mounting
(parallel compensation)
Selection of Contactors
The following tables indicate, for each contactor type, the maximum permissible number of lamps per phase. Air temperature, near the contactor,
must be limited to 55 °C.
Numbers are given for a 230 V voltage distributed between phase and neutral: single-phase (phase + neutral) or three-phase (3 phases + neutral)
distribution, lamps are wired in star connection.
In the case of a three-phase supply without neutral, 230 V phase-to-phase, the permissible number of lamps per phase will be that given in the tables
multiplied by 0.58.
Example: 120 x 100W / 230V incandescent lamps - 400 V three-phase network with distributed neutral.
Calculate the number of lamps per phase: 120 : 3 = 40. On the 100 W line of the incandescent lamp table, contactor A12 is limited
to 38 lamps per phase, you must thus select contactor A 16 which accepts up to 42 lamps per phase.
The selection table for A 50 ... A 110 contactors can be used for the AF 50 ... AF 110 types.
The selection table for AL 9 ... AE 110 contactors can be used for the TAL 9 ... TAE 110 types.

General
The arc switching on d.c. is more difficult than on a.c.
●For selecting a contactor it is essential to determine the current, the voltage and the L/R time constant of the controlled load.
●For information, typical time constant values are quoted hereafter: non inductive loads such as resistance furnaces (L/R ~ 1 ms), inductive loads
such as shunt motors (L/R ~ 2 ms) or series motors (L/R ~ 7.5 ms).
●The addition of a resistor in parallel with an inductive winding helps in the elimination of the arcs.
●All the poles required for breaking must be connected in series between the load and the source polarity not linked to earth (or chassis).

Technical Data
●The tables indicate for the standard contactors the Ie max. operating currents depending on: the utilization category (i.e. L/R) DC-1, DC-3, DC-5
as defined in the IEC 60947-4-1 publication, the operating voltage Ue and the pole coupling details.
Ampere values quoted in these tables are valid for a -25 … +70 °C temperature close to the contactors, as long as the AC-1 Ampere values for
the corresponding ambient temperature are not exceeded.
●Max. switching frequency: 300 cycles/h.
●For switching higher d.c. ratings, we recommend the use of bar mounted contactors, R series (63 … 2000 A).

●The tables indicate for the standard contactors the Ie max. operating currents depending on: the utilization category (i.e. L/R) DC-1, DC-3, DC-5
as defined in the IEC 60947-4-1 publication, the operating voltage Ue and the pole coupling details.
Ampere values quoted in the tables below are valid for a -25 … +70 °C temperature close to the contactors, as long as the AC-1 Ampere values
for the corresponding ambient temperature are not exceeded.
●Max. switching frequency: 300 cycles/h.
●For switching higher d.c. ratings, we recommend the use of bar mounted contactors, R series (63 … 2000 A).

Auxiliary Contacts for Safety Circuits
3-pole Contactors
Mechanically Linked Contact Elements for Contactors
(known as "forced contacts", "positively activated contacts" or "linked contacts").
Definitions from standards: mechanically linked contact elements according to IEC 60947-5-1, Annex L 3.0.
Combination of "n" Make auxiliary contact element(s) and "m" Break auxiliary contact element(s) are designed in such a way that they cannot be
in the closed position simultaneously.
One control circuit device may have more than one group of mechanically linked contact elements.
The table below gives the contactors that offer mechanically linked auxiliary contacts according to IEC 60947-5-1, Annex L.
Mirror Contacts
Definitions from standards: mirror contact according to IEC 60947-4-1, Annex F 2.1.
Normally closed auxiliary contact (N.C.) which cannot be in the closed position simultaneously with the normally open (N.O.) main contact.
The table below indicates the contactors that offer a built-in auxiliary mirror contact.
The CA 5-13, CA 5-22, CA 5-31, CA 5-04 and CA 5-01 (respectiv ely 4-pole and 1-pole auxiliary contact bloc ks) and the CAL 5-11 (2-pole auxiliary
contact block) when fitted on A 9 ... A 75, AF 45 ... AF 75 or AL 9 ... AL 40 contactors have their own N.C. auxiliary mirror contacts.
The CAL 18-11 2-pole auxiliary contact bloc ks when fitted on A 95 ... A 300 and AF 95 ... AF 750 contactors have their own N.C. auxiliary mirror
contacts.
For AF 1350, AF 1650 use 2 N.C. auxiliary contacts in series for mirror contact, one CAL 18-11 on each side of the contactor.

The information provided for AL contactors can also be used for AL..Z... and TAL... contactors.
For each contactor type, see "Accessory Fitting Details".
Direct Opening Action of N.C. Built-in Auxiliary Contacts
Annex K2.1 of IEC 60947-5-1 defines a control switch with direct opening action: "the full contact opening of the break contact element(s) is
obtained when the actuator is moved through the direct opening travel by applying the force stated by the manufacturer".
The N.C. built-in auxiliary contacts of contactors ARE NOT CONCERNED by the annex K.
Nev ertheless, N.C . auxiliary contacts are designed to hav e "direct opening action" and are suitab le f or uses such as lifts / elevators (acc. to EN 81-1).

Contactor Electrical Durability
and Utilization Categories
General
Utilization categories determine the current making and breaking conditions relating to the characteristics of the loads to be controlled by the
contactors. International standard IEC 60947-4-1 and European standard EN 60947-4-1 are the standards to be referred to.
If Ic is the current to be broken by the contactor and Ie the rated operational current normally drawn by the load, then:
●Categories AC-1 and AC-3: Ic = Ie
●Category AC-2: Ic = 2.5 x Ie
●Category AC-4: Ic = 6 x Ie
Generally speaking Ic = m x Ie where m is a multiple of the load operational current.
On next pages, the curves corresponding to categories AC-1, AC-2, AC-3 and AC-4 represent the electrical durability variation of standard contactors
in relation to the breaking current Ic .
Electrical durability is expressed in millions of operating cycles.
For the AC-2 applications, the Ie values are given in the "stator contactor table" (see "Control of Three-Phase Slip-ring Motors").
Curve Utilization Mode
Electrical durability forecast and contactor selection for categories AC-1, AC-2, AC-3 or AC-4
●Note the characteristics of the load to be controlled:
–Operational voltage ...........................................................................Ue
–Current normally drawn ..................................................................... Ie(Ue / Ie / kW relation for motors, see "Motor Rated Operational Powers and Currents").
–Utilization category ............................................................................ AC-1, AC-2, AC-3 or AC-4
–Breaking current ................................................................................ Ic = Ie for AC-1 and for AC-3 ; Ic = 2.5 x Ie for AC-2 ; Ic = 6 x Ie for AC-4
●Define the number of operating cycles N required.
●On the diagram corresponding to the operational category, select the contactor with the curve immediately above the intersection point (Ic ; N).
Electrical durability forecast and contactor selection for mixed duty motor control: AC-3 (Ic = Ie) type switching off while "motor running"
and, occasionally, AC-4 (Ic = 6 x Ie) type switching off while "motor accelerating".
●Note the characteristics of the motor to be controlled:
–Operational voltage ...........................................................................Ue
–Current normally drawn while "motor running" .................................. Ie(Ue / Ie / kW relation for motors, see "Motor Rated Operational Powers and Currents").
–Breaking current for AC-3 .................................................................. Ic = Ie
–Breaking current for AC-4 while "motor accelerating"........................ Ic = 6 x Ie
–Percentage of AC-4 operating cycles ................................................ K (on the basis of the total number of operating cycles)
●Define the total number of operating cycles N required.
●Note the smallest contactor rating compatible for AC-3 (Ue / Ie) on Main Pole Utilization Characteristic table (see "Technical Data").
●For the selected contactor make a note of the following in relation to the voltage using diagram AC-3 in next pages:
–The number of operating cycles Afor Ic = Ie(AC-3)
–The number of operating cycles Bfor Ic = 6 x Ie(AC-4)
●Calculate the estimated number of cycles N' (N' is always below A)
A
N' = 1 + 0.01 K (A/B - 1)
●If N' is too low in relation to the target N, calculate the estimated number of cycles for a higher contactor rating.
Case of uninterrupted duty.
Among the different utilization categories, the uninterrupted duty implies the following remark. The combinated effect of environmental conditions
and the proper temperature of the product may require some disposals. As a matter of fact, for this duty, the use duration prevails over the number
of operating cycles.
For long term service, some verifications of preventing maintenance are needed to check the functionality of the concerned product (consult us).
Over a duration of five years, in these conditions the contactor might present high internal resistance. We recommend to change the contactor or
change the contacts.

Influence of the Length of Conductors
used in Contactor Control Circuit
Permissible single length for the control circuit conductors on contactor closing:
Depending on the coil pull-in power consumption on the supply voltage and on the control circuit conductor cross-sectional area.
Example:
A 9 contactor
Coil voltage: 230 V 50 Hz, contactor coil pull-in power consumption: 70 VA,
control circuit conductor cross-sectional area: Cu 1.5 mm2.
Max. permissible length: 2000 m.
Under certain conditions the excessive length of the control circuit conductors may prevent the contactor from
carrying out closing and opening orders.
–no closing: due to excessive voltage drop (in a.c. or d.c.).
–no opening: due to excessive capacitance (in a.c.).
Contactor Closing (contactor with a.c. or d.c. operated coil)
The voltage drop is due to the pull-in current (pull-in power) and to the resistance of the control circuit
conductors.
The table and graph below can be used to determine the single length of line feeders (distance between the
control device and the contactor coil) in relation to:
●the coil pull-in consumption.
●the supply voltage.
●the connecting wire cross-sectional area.
The graph has been drawn for a max. line voltage drop of 5 %.

Influence of the Length of Conductors
used in Contactor Control Circuit
Contactor Opening (contactor with a.c. operated coil)
Under certain conditions, an a.c. operated contactor does not open when the control circuit is de-energized.
This is due to a critical capacity of the excessively long control circuit line and the type of contactor coil control
layout (see diagrams A and B opposite).
This may be caused by the following factors:
●high control voltage.
●low coil holding consumption.
●low contactor drop-out voltage (according to IEC 60947-4-1: 0.2 to 0.75 x Uc).
If lines longer than those indicated are required, the following measures must be taken:
●select a contactor with a higher rating.
●select a lower control voltage.
●connect "RP" resistance in parallel with the contactor coil:
103
RP =(with C in µF)
C
The table and graph below can be used to determine the single length of line feeders (distance between the
control device and the contactor coil) in relation to:
●the coil holding consumption VA.
●the supply voltage.
●the capacity in µF/km (depending on the control layout).
Wiring diagrams A and B opposite show two supply and coil control wiring examples.

Parallel Connection of Main Poles
Parallel Connection of Main Poles
Purpose: Increasing the a.c. resistive load.
Remarks:
– Parallel connection of main poles to increase the d.c. resistive load is not acceptable.
– Parallel connection of main poles does'nt increase the breaking capacity.
Means: The poles can be connected in parallel via connecting strips: see "Accessories".
– LP and LH for parallel connection of 2 poles,
– LY and LF for parallel connection of 3 poles,
– LG for parallel connection of 4 poles.
The table below shows the uprating factor for Ie / AC-1 max. in relation to the number of poles in parallel and for a max. switching frequency.
2 poles in // 3 poles in // 4 poles in //
