Note that the shock resistant material (MIL-M-14) used for housing and cover is light gray. Terminal Studs Mounting Block Mounting Studs These molded case Navy circuit breakers provide both overload protection for conductors and short circuit protection for all circuit elements such as conductors, motors and starters. They also serve as manual disconnecting means as well as circuit protectors. All Eaton's Cutler-Hammer circuit breakers in this Product Guide meet applicable Navy specifications for "hi-shock." These manually operated breakers are rated from 5 to 4,000 amperes with interrupting ratings from 1,500 to 150,000 amperes. (See "Selector Guide" on Page 2 for ratings and Navy specifications.) Design Features Plug-in Studs Slip Type Connectors Terminal Mounting Block Rear view of breaker showing terminal blocks for switchboard mounting. (Terminal block attached at line end of breaker and removed from load end.) Cutler-Hammer Navy circuit breakers retain all the features of standard commercial type AB DE-ION breakers listed on Page 4 under "standard features." Built to Navy specifications, they incorporate the following Navy requirements: Specific Navy Features Qualified Products -- All Navy circuit breakers undergo rigorous qualification testing to MIL-C-17361 and are listed on the associated Qualified Products List issued by the federal government. (ACB's per MIL-C-17587, ALB-1's per MIL-C-17588, and AQB's per MIL-C-17361.) Shock-Resistant Molded Case -- Housing consists of rear base section and cover molded of glass alkyd material. This material, reinforced glass filled thermosetting plastic, has very high mechanical strength (shock and impact resistance), is both fire and moisture-resistant and provides excellent dielectric characteristics. Anti-Shock Device -- Inertia weight over center pole holds trip bar in latched position under shock conditions but does not prevent thermal or magnetic trip units from functioning on overload and short circuits. Note: Interchangeable trip units are not available in the A101, ALB-1, A50 or A51. Shock and Vibration Resistant -- Navy circuit breakers are all tested to MIL-S-901 for Hi Impact Shock, and MIL-STD-167 for Mechanical Vibration. This test ensures that the circuit breakers will operate properly in the Naval shipboard environment. EMI Resistant -- All Navy circuit breakers with Electronic Trip Units (ETUs) are tested for electromagnetic immunity and emissions per MIL-STD-461 and -462 to eliminate interference from radiated or conducted EMI. 50C Calibrated -- Thermalmagnetic circuit breakers are calibrated for 50C ambient temperature. The calibration of circuit breakers with ETUs are inherently unaffected by ambient temperature. Interchangeable Trip Units -- All thermal and magnetic trip units in AQB circuit breakers are encased in sealed, self-contained units that are interchangeable with other trip units of different ampere ratings within the same frame size. Plug-in Connectors -- All Navy circuit breakers are designed for optional molded plug-in bases in a variety of styles. Smaller breakers (ALB-1, A50 and A51) must be used with the associated bases. Other MCCBs can be converted for direct cable or plug-in mount. Plug in bases are available in a variety of styles depending upon the circuit breaker type. See the specific circuit breaker style for available mounting bases and outline drawings. Note: All A101, A50 or A51 breakers have plug-in connectors. Front or rear connectors determined by mounting base selected. ALB breakers have a clamp terminal on the line end to receive panelboard bus stab projections. Interrupting Ratings to 150 kA -- Navy circuit breakers are available with interrupting ratings up to 150 kA, many using modern fuseless current-limiting technology. Circuit breakers rated 100 ampere and below must be used with associated current limiting fuses to achieve high interrupting capacity. Circuit Breakers for Naval Shipboard Use PG01218003E--January 2010 www.eaton.com 3 General Information Standard Features Arc Chute Moving Arm Operating Mechanism Trip Mechanism Breaker Front Cover Removed Arc Chute Removed Corrosion-Resistant -- All parts are specially treated to resist corrosion. Fungusmoisture resistant treatments for severe atmospheres are available as modifications. Positive Position Indication -- Position of handle always indicates ON, OFF, or TRIPPED. Free-Bearing Surfaces -- Dissimilar metals are used to prevent bearing wear and eliminate sticking. DE-ION Arc Quenchers -- This Eaton development consists of a series of grid plates mounted in parallel between supports of insulating material. The slots in the steel plates are directly over the contacts and draw the arc from the moving contact up into the divided chamber where it is confined, divided, and extinguished. Silver Alloy Contacts -- Special silver alloy contacts prevent sticking and welding, increase contact life and insure low resistance when carrying full-rated load. Quick-Make, Quick-Break Over Center Toggle Mechanism -- Provides quick, positive action in opening and closing of circuits, prevents "teasing" of contacts and reduces contact wear. Complete Interpole Barriers -- Ensure against internal flashovers when faults occur. Common Trip -- Two and three-pole units have insulated common trip bar that opens all poles simultaneously when an overload occurs on any one, thus eliminating possibility of single-phasing. Molded Operating Handle Removed 4 Circuit Breakers for Naval Shipboard Use PG01218003E--January 2010 www.eaton.com Tested Accuracy -- All tripping members have ground and polished latch surfaces heat treated to prevent galling or later distortion. All parts are tested in temperaturecontrolled atmosphere to ensure correct calibration and perfect mating. Each breaker is thoroughly tested. Factory Sealed -- Smaller breakers are factory sealed to prevent tampering with calibration. Interchangeable trip units are individually sealed. (c) Timeless Images Application Designed primarily for circuit protection, Cutler-Hammer Navy circuit breakers are used in lighting and power panels, switchboards, distribution centers and load centers aboard ship. The photograph above illustrates the use of molded case circuit breakers and air circuit breakers in a typical Navy switchboard.

Interrupting Rating 5,000 amperes I.C. Non-Interchangeable trip unit. Class Hi-Shock MIL-S-901, 50C ambient. The Type AQB-A51 molded case circuit breaker is a 500 Vac maximum rated device with 50 ampere maximum continuous current at 60 Hz. The AQB-A51 is a form, fit and function replacement for the AQB-A50 circuit breaker with enhanced overcurrent protection features. In the AQB-A51, overcurrent protection is provided in all three poles. This not only makes the breaker suitable for use in "grounded" three-phase systems, but offers enhanced performance of the instantaneous trip feature when used in ungrounded systems. In three phase distribution systems with either a solidly or "effectively" grounded neutral, fault currents can occur that will be evident in only one pole, so protection is needed in all three poles. The enhanced instanta- neous trip feature is valuable in the selective coordination of the AQB-A51 with upstream AQB breakers. The AQB-A51 circuit breaker has an interruption rating of 5000 amperes asymmetric. The NQB-A51 breaker is a nonautomatic design of the AQB-A51. Since the tripping elements are omitted, it is used as a manual disconnect. The NQB-A51 has a maximum continuous current rating of 50 amperes.

The memory effect comes into play if a current above the Long Delay Pick Up value exists for a time and then is cleared by the tripping of a downstream device or the circuit breaker itself. A subsequent overload will cause the circuit breaker to trip in shorter time than normal. The amount of time delay reduction is inverse to the amount of time that has elapsed since the previous overload. Approximately five minutes is required between overloads to completely reset memory.

It requires that they carry 150% of current ratings for at least one hour and that thermal elements initiate tripping at 225% rated current within one hour and at 600% in 25 seconds plus or minus 25%. The instantaneous magnetic settings for each continuous ratings are based on intended applications. (Thermal tripping tests are conducted with all poles in series in 50C ambient; each pole is tested individually to check magnetic settings.)

The result will be the ideal trip unit rating. However, since trip units are furnished only with standard ratings as per Navy spec., select the standard trip unit whose rating is equal to or one rating higher than the ideal rating. Circuit Breakers for Naval Shipboard Use PG01218003E--January 2010 www.eaton.com 59 Types AQB-LF100, AQB-LF250 Circuit Breakers for Naval Shipboard Use Types AQB-LF100, AQB-LF250 Breakers Type AQB-LF100, 100 Amperes Maximum, Type AQB-LF250, 250 Amperes Maximum, 500 Volts ac, 100,000 Amperes I.C. Application AQB-LF100 and AQB-LF250 circuit breakers are for use in low-voltage distribution systems where available fault current exceeds the interrupting ratings of standard molded case breakers but does not exceed 100,000 amperes. Like standard Navy breakers, they are designed for use in switchboards, loadcenters and panelboards. AQB-LF circuit breakers are available in three-pole design and for rear connection only. Description AQB-LF100 Fused Navy Circuit Breaker These breakers are essentially standard Navy circuit breakers incorporating current limiting fuses in one compact device. The fuses are mounted in a removable molded housing which plugs into and becomes an integral part of the breaker. Fuses are easily replaced from the front simply by loosening four screws and pulling out the fuse housing. An interlock prevents the breaker from being closed if any of the three fuses are blown and the fuse housing is designed so that all three fuses must be unblown before the housing can be mounted in its correct position on the breaker. Removal of the fuse housing automatically opens breaker and provides visual assurance that the circuit is disconnected. Fuse Trip Lever Instantaneous Trip Adjusting Wheels Operation The thermal-magnetic trip unit of the standard breaker provides protection on overloads and short circuits below a predetermined value without affecting the fuses. However, these specially coordinated fuses assume the fault clearing duty on high magnitude short circuits and extend the interrupting capacity to 100,000 amperes. The common trip feature of the circuit breaker is retained so that all poles open when any fuse blows. Fast acting current limiting fuses clear short circuits in less than one-half cycle. Consequently, peak let-through currents are greatly reduced and bus-supporting members or current carrying parts do not have to be designed to meet maximum peak current.

Description The AQB-A253, 250 ampere circuit breaker, is form and fit interchangeable with the AQB-A250 but has an electronic trip unit and higher interrupting capacity. It is available in a 3-pole, ac current version only. If used to protect two ac poles, connect only the outer poles. It is a universal style with a common trip unit and 60 Hz and 400 Hz ratings. Specifications: MIL-C-17361 70 100 - 250 amperes, 100% Rated. AQB-A253: 500 volts ac, 60/400 Hz. AQB-L253: 500 volts ac, 60 Hz. NQB-A253: 500 volts ac, 60/400 Hz. No dc. Interchangeable Electronic Trip with rms sensing. 3-pole. The AQB-L253 is a high interruption version of the AQB-A253 in the same external package. It uses fuseless current-limiting technology to achieve 100 kA interrupting capacity so it can be used to replace the AQB-LF250 without the logistic concerns of fuse replacement. The AQBL253 utilizes a smaller package and offers a significant weight reduction compared to the LF250. The -L253 is available in only a 60 Hz version. The NQB-A253 circuit breaker has a maximum continuous current rating of 250 amperes. They are used only as disconnects, since they do not include an automatic opening device. The AQB-A253 and L253 are supplied with a universal trip unit that is used in all AQB versions. The trip unit must be equipped with an adjustable rating plug (ordered separately) that determines the continuous current rating of the complete circuit breaker. Two adjustable rating plugs are available. One covers the continuous current settings of 250, 225, 200 and 175 amperes and the other covers the current settings of 160,150, 125 and 100 amperes. The interchangeable electronic trip unit (ETU) has an adjustable time-current curve with selectable values of Short Time Delay Pickup (STDPU) (scaled to the CCS) and Short Time Delay (STD) for improved coordination with upstream or downstream devices. The trip unit also has an instantaneous override trip fixed at 7500 A (30 x frame rating). The ETU can emulate the trip curve of the AQB-A250 by setting the STD to INST and using the STDPU to emulate an adjustable INST setting. Principle of Operation These circuit breakers are designed to provide the most modern form of low voltage circuit protection technology available, providing high interruption ratings and flexible coordination without the need for current limiting fuses. The breakers use modern electromagnetic design principles to increase the interrupting capacity (IC) to significantly higher levels than comparable AQB-A250 breakers. The AQB-L253 uses a "reverse loop" conductor design and "magnetically unlatched" contact arms to provide very high interrupting capacity while limiting the let-through current and limiting the fault duration to a few milliseconds. Circuit Breakers for Naval Shipboard Use PG01218003E--January 2010 www.eaton.com Ordering The circuit breaker is available in three styles, an AQB-A253 (standard IC), an AQB-L253 (high IC) and an NQB-A253 (non-automatic) switch. The breaker is completed by adding one of two styles of rating plugs, one which covers the continuous current range from 250 - 175 amperes and another which covers the range from 160 - 100 amperes. An internally mounted auxiliary switch, a shunt trip and an undervoltage release are also available.

Calibration response in short delay pickup range is same for 1, 2 or 3 poles in series. 6. There are memory effects that can act to shorten the long delay. The memory effects come into play if a current above the long delay pickup value exists for a time and then is cleared by the tripping of a downstream device or the circuit breaker itself. A subsequent overload will cause the circuit breaker to trip in shorter time than normal. The amount of time delay reduction is inverse to the amount of time that has elapsed since the previous overload. Approximately five minutes are required between overloads to completely reset the memory.

AQB-LL400QS Breaker Motor Operator Mounted on Circuit Breaker AQB-L400QF, AQB-L400QM and AQB-LL400QS current limiting circuit breakers are designed for installation in switchboards for protection of generators and feeders and branch circuits with available fault currents of 150,000 amperes maximum. Description The Navy Type AQB-L400QF, AQB-L400QM, and AQBLL400QS molded case circuit breakers are 500 Vac maximum rated devices with electronic trip units rated at 400 amperes maximum continuous current at 60 Hz. The circuit breakers are assembled as 3-pole units which may be used as 2- or 3-pole devices. The circuit breakers are designed to MIL-C-17361 and meet the requirements of Class HI-shock, MIL-S-901. The circuit breaker electronic trip unit has adjustable short delay time and pickup trip settings which can be readily changed at the operator level to meet the shipboard system trip requirements. Four interchangeable rating-plugs are available to select the continuous current rating of 250, 300, 350 or 400 amperes. Also provided is a non-adjustable inverse time delay tripping action for overload conditions, and instantaneous tripping for protection against short circuit conditions that exceed the preset short delay pickup setting. In open air at 50C, the circuit breaker will carry continuously a current equal to the ampere rating of the installed rating plug. The calibration of the trip unit is insensitive to ambient temperatures over a range of -20C to +70C. Operation The AQB-L400QF, AQBL400QM, and AQB-LL400QS current limiting circuit breakers (without the need for current limiting fuses) are designed to provide circuit protection for low voltage distribution systems. The circuit breakers will disconnect a load from an electrical supply when the handle is operated, when an overcurrent or short circuit condition develops, or when the push-to-trip button in the trip unit is manually pressed. A complete breaker consists of a breaker, rating plug plus mounting blocks and is available with numerous attachments such as electrical operator, shunt trip, undervoltage release and auxiliary switches to perform varied auxiliary functions. The circuit breaker has a springloaded independent over-toggle operating mechanism that provides a quick-make quick-break trip-free operation. The operating mechanism also provides the electro-mechanical means to open the contacts when trip conditions occur. When current is flowing through the contacts of the circuit breaker, the positions of the lower contact arms and the moving contact arms induce opposing magnetic fields. The resulting opposing forces along the magnetic flux lines cause rapid contact blow-apart under high current fault conditions. The AQB-L400QF and AQB-L400QM circuit breakers have slot motors for each moving contact arm to intensify the magnetic field and further increase the blow-apart effect.

Up Upper pper Co ontact Arm Slot Motor Lower Contact m Line End Conductor MAGNETIC FIELD WITH SLOT MOTOR A push-to-trip button is provided to manually trip the circuit breaker. When the button is pressed, a plunger rotates the latch lever causing the circuit breaker to trip. All trip units are built into the circuit breaker frames and use electronic sensing elements. The Types AQB-L400QF, AQBL400QM, and AQB-LL400QS Seltronic trip units provide protection functions. All trip units are supplied electrically from current sensors mounted on the main conductors in the circuit breaker base. A field-installed rating plug determines the continuous ampere rating of the trip unit. An electrical interlock causes the circuit breaker to trip at current levels of 75% or more if the rating plug is not installed. Under fault conditions, the trip unit will initiate a trip signal and energize the flux shunt trip. When the flux shunt trip operates, the plunger extends and rotates the trip lever. As the trip lever rotates, the latch lever rotates which unlatches the trigger and the circuit breaker trips. Overload Trip -- The trip unit initiates an ultimate trip of the circuit breaker within one hour for an overload of 131% to 156%, and in less time for higher overloads. Short Delay Trip -- For short circuit conditions that exceed the short delay pickup setting but not the instantaneous (override) pickup, the trip unit initiates a trip after the selected short delay time setting. Instantaneous Trip -- For short circuit conditions that exceed the instantaneous (override) pickup value, but not the current-limiting threshold, the trip unit initiates a trip with no intentional delay.

This combination of an AQB-L400/LL400 circuit breaker and the Eaton Adapter Kit provides a direct oneto-one current limiting type L400 circuit breaker replacement for an already installed fused type LF400 circuit breaker. Existing AQB-L400/LL400 circuit breakers in the field (manufactured prior to August, 1992) may need a factory modification to accept the Adapter Kit. Contact Eaton for details, if there are any questions. An Eaton AQB-L400 Adapter Kit provides the means for converting the normally male configured primary connections of an AQB-L400/LL400 current limiting circuit breaker to female configured primary connections, normally associated with an AQB-LF400 circuit breaker. A close out plate, attached directly to the front of the AQB-L400 circuit breaker with four mounting screws, provides the deadfront cover required to complete the conversion. This close out plate blanks out the hole in the switchboard door or cover, through which the LF400 fuse pack protruded. The adapter kit itself is comprised of line and load side adapter blocks, six female spring loaded primary connection adapters, a close out plate, and four mounting screws. 82 Eaton Adapter Kit Parts Before Installation Net Weight 34 Lbs.

The circuit breaker is a device for interrupting, in air, a circuit between separable contacts under normal and abnormal conditions. It is supplied as a complete removable assembly including drawout, stationary frame and secondary control contacts in a three-pole construction. The main power circuit consists of butt type main and arcing contacts. The function of the main contacts is to carry full-rated current and short circuit current when the circuit breaker is closed. The arcing contacts transfer the current from the main contacts to the arc chutes when breaking currents. Each contact assembly is fastened to a common driveshaft via an insulated drive link. By rotating this driveshaft, the operating mechanism actuates the contacts of all poles simultaneously. These contacts are quick make and break, under all conditions. ACB3200/4000HR Air Circuit Breaker Shown Mounted in its Stationary Drawout Cassette ACB3200/4000HR Air Circuit Breaker Removable Element, Rear View, with Lifting Beam ACB3200/4000HR Air Circuit Breaker Stationary Drawout Cassette The circuit breaker is of the trip free design in any position of the closing stroke and may be tripped before the contacts touch. While an open operation exists, the moving contacts will return and remain in the open position even if a manual or electrical close operation is maintained. The closing mechanism will not reclose the circuit breaker after such tripping until the closing control circuit is opened and then reclosed. Three current sensors are installed. Two current sensors are fixed to the stationary element and surround the lower outer main poles. The third current sensor is fixed to the stationary element and surrounds the top center main pole. These ring-type current transformers are designed to monitor the current and to signal the solid state overcurrent trip device to trip the circuit breaker whenever current exceeds its long time delay and short time pickup settings. The trip knob located in the front of the operating mechanism provides a means for tripping the circuit breaker manually. At the top of the circuit breaker, surrounding each contact structure, is the arc chute assembly. It is designed to extinguish the arc that is drawn when the contacts open. Each contact assembly is mounted on an insulated panel bolted to the back panel of the circuit breaker's removable element. The moving contact assembly is designed to make or break a main power circuit by moving onto or out from the fixed main contacts. Instantaneous overcurrent trip devices are attached to the two lower outer poles of the circuit breaker. These calibrated devices will trip the circuit breaker whenever the current exceeds the predetermined instantaneous setting. The operating mechanism transmits the closing force to the drive shaft. It is centrally located in the front of the circuit breaker. The ON/OFF indicator, located in the front of the circuit breaker, is fastened to the drive shaft above the operating mechanism. This device indicates whether the circuit breaker is open (OFF) or closed (ON). Anti-rebound catches are provided to prevent reclosing of the contacts when the circuit breaker is tripped. These are mounted on the side plates of the breaker. They also function as shock catches preventing contacts of an open breaker from closing. The shunt trip circuitry, which acts through the magnetic trip device located on the left side of the operating mechanism assembly, provides the means for electrically tripping the circuit breaker from a remote location with out regard to load conditions in the circuit. Customer supplied 120 Vac Power (standard) is converted to 30 Vdc by a control panel for the magnetic trip device. The auxiliary switch, actuated by the opening and closing of the circuit breaker, is incorporated to open and close certain contacts in protective and control circuits. The auxiliary switch is linked to the driveshaft which is located above the operating mechanism.

The closing contactor, attached to the left-hand side of the removable element frame, controls the supply of current to the closing coil (customer supplied 450 Vac). An undervoltage trip device (when supplied) mounted to the right-hand side of the mechanism will trip the circuit breaker when the undervoltage coil is de-energized by loss of voltage. Provision is provided for two indicating lamps. These lamps are only supplied when specified. A "Tripped on overcurrent" lamp is always provided. A rectifier unit permits the use of an alternating current source for closing the circuit breaker. The lockout mechanism prevents the circuit breaker from being racked in or out while the circuit breaker is closed, and prevents closing of the circuit breaker while the removable element is being reached in or out. NET WEIGHT Primary disconnect assemblies are mounted on each phase of the circuit breaker to provide a separable electrical connection between the supply circuit and the circuit breaker. A movable secondary disconnect assembly, fastened to a channel structure mounted on the bottom rear of the circuit breaker removable element, permits the withdrawal of the circuit breaker without disconnecting the wiring. 114 The circuit breaker may be racked into or out from the Connected position from or to the Disconnected position by turning the withdrawal mechanism drive shaft which is located on the right of the operating mechanism.
