A Power supply module This module provides control source for DISPLAY module,trip indicator and several indicators (LEDs). (Even when the control power source is off, the function of over current protection and ground fault protection are effective.) There are two types of power supply modules, one is only of power supply function, the other is power supply function with output contact (6 contacts). D C F E B Main setting module This module provides the function of over current protection. It is possible to select the three setting module according to application. (see page -6) Neutral protection of rated current (00%) function is standard at pole breaker. H Optional setting module (option) Additional functions and characteristics can be selected by optional setting modules. A B C D E F Display (option) Several measuring data (current, voltage, power etc) and alarms can be displayed with this module. Extension module (option) This module is required when installed VT unit, display module and each interface unit. Load current LED (standard) This indicator displays the maximum current of phase. RUN LED, ERR. LED (standard) This indicator displays the ETR situation (Run or Error) Trip indicator LED (standard) This indicator displays the trip cause. G F Pre-alarm(PAL) (standard) This indicator displays the Pre-Alarm situation when exceed the setting current. When it installed power supply module with contact, the output contact of Pre Alarm is available. * The output is reset when the electric current goes below the set level after an alarm is set off. G RESET button (standard) When push this reset button, trip indicator, and Pre-Alarm will be reseted. And when the instantaneous test by MITSUBISHI special tester and push this reset button, as a result of LTD and STD function become ineffective. H TEST terminal (standard) This terminal already installed as standard. This terminal is used for testing by the field test device (Y-000). (see page ) OCR alarm (AL) (standard) When it happen to trip by over current, ground fault ( GFR ) and Earth leakage ( ER ), it issue a warning alarm. Neutral pole overcurrent protection (NP) (standard) When harmonics in load current are large, the current on neutral pole exceeding rated current may flow. Harmonics may cause some troubles. Neutral pole overcurrent protection prevents them by operating at 00% of rated current on neutral pole. MCR:Making current release (option) Just under the breaker closing operation ( from open to close ), Instantaneous characteristic become effective, but after closing the breaker, instantaneous characteristic become ineffective. When you order the MCR switch, MCR switch is built in the main body. If MCR switch is built in the main body and the adjust dial of INST/MCR on main setting module is set the MCR position,mcr function become effective. TAL (option) When the temperature of main contacts exceed normal temperature level, temperature alarm is indicated at LED ( on main setting module ) and output by contact ( only installed power supply with output contact ). If TAL is installed in the breaker according your order, Temperature alarm ( LED ) function become effective. When the temperature goes down within normal tempter level, the temperature alarm will be reset. NCT (option) Neutral CT is required for Ground fault or Neutral pole protection, when pole breaker is used for phase wires system. ZCT (option) ZCT is required for a few amperes earth leakage protection, and is combining ER plug. (see page 8)

MCR switch (MCR-SW) If MCR switch is built in the breaker and the dial for INST/MCR on Main setting module is set to the range of MCR position, MCR function is operative. MCR function: During a closing operation of the breaker, Instantaneous characteristics is operative. And it becomes inoperative when the breaker is in the closed position. Temperature alarm (TAL) If TAL sensor is built in the breaker, temperature alarm is operative. When the temperature of main contact exceeds normal level, temperature alarm is indicated by LED on main setting module and also the output contact is made energize if power supply with output contact is installed. It is possible to know temperature rising which is caused by wear of main contact because TAL sensor is installed near main contact. When the temperature of main contact goes down to the normal level, temperature alarm turns off automatically. Field test device (Y-000) The electronic trip relay can be checked by this field test device when the breaker is at test position or disconnect position. The breaker will trip when tested with this device.

Current sensor coil The current in each phase flowing through in the breaker is detected. A air core coil which has good linearity is achieved. Power supply circuit This part convert power supply CT energy to constant voltage for respective circuits in the ETR. ASIC This amplifies signal detected by the current sensor coil, and detects ground fault current by vector composition. Microprocessor The microprocessor integrates each phase current waveforms from the ASIC and performs processing for overcurrent protection and others. Characteristic setting module The module for the characteristic setting of the ETR. Several LEDs The load current LED give a figure of current in percent by CT energy. Trip indicator and pre-alarm are indicated by control power supply. RUN and ERR. LED indicate breaker's condition by control power supply or ten-odd percent of CT energy. Power supply with contact output This outputs contact signal at fault cause (including pre-alarm) and at other alarms. A control supply is necessary for this function.
Setting procedure Press the screwdriver in the direction of the arrow to open the cover Prepare a small flat tipped screwdriver. 6mm max. 0.8mm max. Side view of the flat tip ETR cover Operating hole for resetting Sealing hole Insert the flat tipped screwdriver into the opening of the ETR cover. Then, lightly turn the screwdriver to the upside as shown in the left figure, and the ETR cover will open. There are two kinds of switches for characteristics setting and for trip indicator reset. They should be used as follows. ➀ Adjustable in steps Rotary code switch is used. Do not set the switch at points between steps. The setting value is same when the switch is positioned at the thick line. (Set the switch with a torque of 0.0N m or below.) (XIu) ➁ Push-button This is for temporary operation, and press it with force of N or less. ➀Adjustable in steps ➁Push-button When the characteristic is set up, use a device like a field tester, etc to make sure that the required characteristic has been set. At sealing, seal the ETR cover by using the sealing hole at the top of the ETR cover. Sealing hole
