Fixing bolt

For AE4000-SW ~ AE6300-SW, always tighten the fix- ing bolts on both sides of the cradle as shown in Table 13-5, and securely fix the breaker.

When the breaker is inserted to the testing position, the drawout position indicator shows TEST position, and the lock plate is protruded automatically, locking the drawout handle rotation.

(Caution) Do not rotate the drawout handle while the lock plate is protruded.

TEST position

Fig. 13-3

Insert the lock plate, and rotate the drawout handle clockwise. When the breaker is inserted to the CONNECT posit ion, the lock plate is protruded automatical ly, completing the insert operation. At this time, the drawout position indicator shows the CONNECT position. For all breaker types, the operation load becomes heavy during operation from the TEST position to the CONNECT position or at the main circuit junction insertion position, but this is not a fault.

Fig. 13-4

(Caution) (a) After completing the insertion, do not rotate the

drawout handle. (b) The drawout position indicator shows the position

Electric open/close operation

< Closing > Opening operation can be performed electrically by using a closing coil (CC). By applying the rated voltage to A1 and A2 on the control circuit terminal block, the breaker can be closed. The pumping preventing relay that performs only one oper- ation with one input command is built in. To close again, turn OFF the closing coil control supply (between A1 and A2 ) once, and apply the rated voltage again. For a closing command to CC, wait at least a 0.5 sec. interval after completing charging and turning OFF the breaker.

When an undervoltage trip device (UVT) is equipped, the breaker does not close unless the power supply is applied. (After applying the control supply to UVT, wait 1.5 sec. for the closing operation to become available.) I f undervoltage tr ipping deviceUVTis UVT with a-contact, wait for 1.8 sec. Instead of 1.5 sec.

(Caution) For a closing command to CC after completing charging, wait at least a 0.5 sec. interval. If a clos- ing command is given within 0.5 sec. after charging completion, the design life of the opening/closing operation may be shortened. In some cases, the breaker does not close by a closing command given within 0.5 sec. after a manual OFF operation or an OFF operation by SHT.

< Opening > Opening operation can be performed electrically by using a shunt trip device (SHT) or undervoltage trip device (UVT). For SHT, apply a rated voltage to C1 and C2 of the control circuit terminal block. For UVT, open between the trip terminals DT1 and DT2 of the control circuit terminal block. (A short-circuit bar is equipped when shipped from the factory. Remove this be- fore using.) Alternatively, turn OFF the voltage applied to D1 and D2 .

< Function description of each part > ERR. LED, contact output

When any abnormality or setting failure is found in the ETR, this provides a notification of the abnormal status. When the power supply type is P3 ~ P5, contact output is given between 513 and 574 on the control circuit terminal block. Functional abnormality in ETR (microprocessor, H/W) Incorrect setting (mis-setting of Int/MCR) Abnormality in in-breaker wiring related to ETR

RUN LED (ETR) ETR indicates the operable state. If the control power supply is applied, or when approx. 10% of the rated current flows to the main circuit, the internal circuit is activated, turning on this LED.

RUN LED (option setting module) Option This indicates that the option setting module is in an operable state. If the control power supply is applied, or when approx. 10% of the rated current flows to the main circuit, the internal circuit is activated, turning on this LED.

Trip cause indicator (LED, contact output) Option The cause of a trip is indicated by LED. When the power supply type is P3 ~ P5, a contact output is given between 513 (common) and 524 , 534 , 544 , or 554 on the control circuit terminal block. PAL LED will blink when the current exceeds the pre- alarm current setting (Ip), and will be lit after 1/2 of the LTD time is passed. At this time, the contact output will also be made.

TAL LED, contact output Option The ETR temperature detector becomes operable when a TAL sensor is installed. When the power supply type is P3 ~ P5, a contact output is given between 513 and 564 on the control circuit terminal block. When the temperature drops, the output will be reset. To retain the output, use an external sequence.

MCR (Making-current release) Option The setting can be switched between the instantaneous current (INST) and MCR functional current (MCR). In the MCR setting, INST characteristic is enabled from the time of breaker closing (OFF to ON), and after closing, the INST characteristic becomes disabled. If specified at the time of ordering, an MCR switch is built in to the breaker. When shipped from the factory, this is set to the INST side.(Fig. 21-2)

RESET button To reset the trip cause indicator (LED, contact output), use the RESET button in front of ETR, or short-circuit RS1 and RS2 on the control circuit terminal block for 0.5 seconds or longer. (The power supply type P1 and P2 are not provided with the function to reset from the control circuit terminal block.) There is also a function to temporarily lock LTD and STD to test the INST characteristic by using a dedicated field testing device. (For operating instructions, refer to the instruction manual of the tester.)

(1) Overcurrent protection is powered by the CT, which is built into the breaker. It is operable regardless of the external power supply. Ground fault protection (GFR) is also operable at 0.2 to 1.0 rated current (In) settings, regardless of the control power supply.

(2) 6 contact outputs are set as below.

Self-hold type ....The output state is held until it is reset.

Auto-reset type...Output is reset upon returning to the normal condition.

With the power supply types P3 and P4, high-sensitivity relays are used for contact outputs. Because of that, contact outputs may trigger chattering noise (approx. 1 ms of mis-outputs) at breaker opening/closing in some panel installation conditions. When us- ing the product in a fast-response sequence, install a filtering circuit of a few milliseconds or perform double reading of samples.

Note 1: LTD operating time tLTD is calculated by the following equations.

The accuracy of operating time is 30% (1.5Irload current<4Ir) or 20% (4Irload current). LTD operating time is 0.8s(FLAT) when the operating time becomes 0.8s or less.

Note 3: When Tsd = "0.06" setting, operating time is 0.04~0.08s. I2t is selectable : ON or OFF.

Setting procedure for the electronic trip characteristics

Prepare a small flat tipped screwdriver.

Insert a flat tipped screwdriver into the upper opening of the ETR cover. Then, lightly push the handle as shown in Fig. 28-1 to open the ETR cover.

There are 2 types of switches. Operate them accordingly.

(a) Stepping type This is a rotary stepping switch. Do not stop in be-

tween steps. If the dial is in the middle, the settings on either side

are enabled. Operate in the range of 0.02N.m torque or less. When MCR (option) is not attached, Ii is set as

shown in Fig. 30-3. Do not set to the Do not set area. Always set to the INST side. (For the function descriptions of MCR, refer to P.21.)

In the bold line area, where there is a range, the set- ting is the same for the entire area. (Fig. 30-4)

Control circuit connecter (drawout type)

For Power supply type P3 and P4, the high sensitive relay used in contact output may cause the chattering noise (wrong output of 1ms level) during ON and OFF operation, depending on the Panel placing condition. When it is used in the quick responsive sequence, the lter circuit of a few milli-second (ms) should be provided or the double reading sampling should be implemented.

Since some terminals are polarized, the wiring should be done correctly as the polarity shown in the wiring diagram when the control voltage is DC. Auxiliary switch (AX) Standard type has no polarity.

OCR alarm (AL)

The contact output of the OCR alarm (Standard type AL) is the one-pulse output and the output time is 30~50ms. For this reason, this output needs self-holding circuit.

When a coil load is connected in the same control circuit as the ETR, surge absorbers are required to absorb the surge voltage.

For the drawout type, the cables should have the length which allow the control circuit terminal block to be moved to the left or right by 5mm.

Under voltage trip device (UVT)

Use the switch that can open and close 150V DC, 0.5A for remote trip. Remote trip terminal has short bar at shipment, so remove it before using this function. Disconnect the voltage input wires during dielectric testing of main circuit.

As CC is one-pulse driven, it is not necessary to insert AXb for burning prevention purposes. Inserting AXb will cause anti-pumping function to be ineffective.

Closing coil (CC)

FG (Terminal: P4 ) is the protective earth for power supply (Terminal: P1 , P2 ). It is recommended to use this terminal to reduce surge (M8 screw required).

Alarm reset (Terminal: RS1 and RS2 ) is available only for Power supply type P3, P4 and P5. For Power supply type P1 and P2, it can not be reset from the Control circuit terminal block ( RS1 and RS2 ).

Shorting b-contact (SBC)

SBC can be provided for all AX b contacts. At the time of shipment from factory, SBC is already connected to control circuit terminal block. Only one more crimp terminal can be added on contact, overlapping with SBCs contact on Terminal: 11 ~ 51 .

where all of the following conditions are met. Unless otherwise specified, use the AE Series air circuit breaker in the following environment. Standard ambient temperature

Use in the range of +40 C max. and -5 C min. However, the average temperature over 24 hours must not exceed +35 C.

Altitude: 2000 m (6600 feet) or less. Environmental conditions

The air must be clean with the max. temperature of +40 C and the relative humidity of 85% or less, and without condensation. Do not use and store in an atmosphere with corrosive gas, such as sulfide gas and ammonia gas. (H2S 0.01 ppm or less, SO2 0.05 ppm or less, NH3 0.25 ppm or less)

Installation condition Install the AE Series air circuit breaker in accordance with the instructions on the catalog and the instruction manual.

Guideline for replacement Expected product life is 15 years in the standard operation environment. Time of replacement is highly influenced by the operation environment. Refer to the inspection and maintenance section of this instruction manual.

2. Special operation environment When the product is used in a condition other than the

standard operation environment, its service life may be shorter. Special operation environment

Operation with high temperature and high humidity. Operation in an environment where corrosive gas is present.

Special ambient temperature When the ambient temperature exceeds +40 C, uninterrupted current is reduced.

Special altitude When using the product at an altitude over 2000 m, heat dissipation becomes less. This leads to a reduction of the operation voltage, current capacity, and breaking capacity. The dielectric strength is also lowered by the air pressure. Please contact us for details.

Inspection and maintenance

The maintenance and inspection items and frequency differ by their operation environment. Carefully read the contents of the manual and perform thorough inspection and maintenance.

If the electricity cannot be shut off, wear rubber gloves and shoes, stand on a rubber mat, and use insulated tools. Pay special attention to the insulation between the human body and live parts as the person must approach close to the live parts. Normal closing/opening operation is safe as the operation parts are insulated with molded material from the live parts.

Inspection and maintenance should be performed by an expert with the required knowledge. Failure to do so could result in electrical shock.

Inspection and maintenance should only be performed after turning off the upper breakers and verifying that there is no current flowing. Failure to do so could result in electrical shock.

< Purpose> Inspection: The purpose of inspecting breakers is to maintain the breaker performance and to prevent accidents caused

by aging parts. This can be achieved by finding faulty parts at an early stage and by replacing consumable and wearable parts in a timely manner.

Maintenance: To maintain the breakers performance, periodic servicing including lubrication is required. Please contact our service department. Do this once every 2 periodic inspections.

1. Guideline for inspection and replacement

1.1 Guideline for periodic inspection, maintenance and replacement based on the operating period and environment The initial inspection should be performed once after 1 month of operation. After that, periodic inspections should be per- formed according to the operation environment.
