ON THREE POLE BREAKERS ONLY (NOT EIGHT PHYSICAL POLES), HAVING GROUND FAULT FUNCTIONALITY, AJUMPER INSTALLED FROM B-6 TO B-7 WILL ENABLE SOURCE GROUND FAULT SENSING AND DISABLE RESIDUALGROUND FAULT SENSING. INPUTS B-4 AND B-5 WILL BE REASSIGNED FOR SOURCE GROUND SENSOR INPUTS.2. ALL CONTACTS SHOWN WITH BREAKER IN OPEN POSITION AND WITH TRIP UNIT IN “NON-TRIPPED” STATE (OTSSWITCHES) AND SPRING NOT CHARGED.3. THE SPRING RELEASE ACCESSORY CONSISTS OF A “SR” COIL AND A P.C. BOARD. THE PRINTED CIRCUIT BOARD PRO-VIDES A .20 SECOND PULSE FOR THE CLOSING OPERATION. VOLTAGE MUST BE REMOVED AND THEN REAPPLIED FORSUBSEQUENT OPERATION.AN OPTIONAL LATCH CHECK SWITCH (LCS) ACCESSORY MAY BE CONNECTED TO THE SPRING RELEASE. THE (CLOSED)LCS DELAYS THE SPRING RELEASE PULSE UNTIL THE BREAKER MECHANISM IS READY TO CLOSE (CHARGED ANDRESET). (THIS WILL INSURE THAT THE LATCH WILL ALWAYS BE IN THE PROPER STATE BEFORE THE SPRING RELEASEPULSE IS INITIATED). IF VOLTAGE IS MAINTAINED TO THE SPRING RELEASE, THE CLOSING PULSE WILL OCCUR WHENTHE MECHANISM IS CHARGED AND RESET (LCS OPEN). VOLTAGE MUST BE REMOVED AND REAPPLIED TO THE SPRINGRELEASE FOR SUBSEQUENT OPERATION.4. TO PROVIDE SELECTED TIME DELAYS FOR SHORT TIME AND/OR GROUND TIME FUNCTIONS FOR TESTING OR NON-ZONE INTERLOCKING APPLICATIONS, A JUMPER FROM B-8 TO B-9 IS REQUIRED.5. 3 WIRE CRIMP IF HIGH INST TRIP MODULE IS SUPPLIED.6. NORMALLY OPENED CONTACT PROGRAMMED AS RELAY A. VIA DIGITRIP FRONT PANEL. (ALARM CONTACT). THIS CANALSO BE ASSIGNED TO INDICATE MAINTENANCE MODE FEATURE IN USE.7. NORMALLY CLOSED CONTACT PROGRAMMED AS RELAY B. VIA DIGITRIP FRONT PANEL. (BLOCK CLOSE CONTACT)8. NORMALLY OPEN CONTACT PROGRAMMED AS RELAY C. VIA DIGITRIP FRONT PANEL. (LATCHING CONTACT)9. ON 4-POLE BREAKERS (ACTUALLY 8 PHYSICAL POLES), THE NEUTRAL CURRENT SENSORS ARE LOCATED WITHIN THEBREAKER FRAME. THE SECONDARY CONTACTS B-4, B-5, ARE NOT WIRED OUT.10. MOTOR OPERATOR SWITCH SHOWN WITH BREAKER CLOSING SPRING DISCHARGED.11. FOUR POINT SOCKET USED HERE.12. SECOND SHUNT TRIP MAY BE INSTALLED (USING A-7, A-8 CONTACTS) IN PLACE OF UVR. THIRD AUX SWITCH NOTAVAILABLE WITH SECOND SHUNT TRIP.13. ONLY ONE LATCH CHECK SWITCH MAY BE INSTALLED. USE OF CUSTOMER ACCESSIBLE LATCH CHECK SWITCH (B-29,B-30) IN SERIES WITH SPRING RELEASE DEFEATS ANTI-PUMP FUNCTION AND IS NOT RECOMMENDED. SEE NOTE 3 FORSPRING RELEASE LATCH CHECK SWITCH.14. THE OTS (OVERCURRENT TRIP SWITCHES) WILL OPERATE DIRECTLY FROM THE DIGITRIP DRIVING THE TA (TRIP ACTU-ATOR) TO TRIP THE CIRCUIT BREAKER. THE OTS REQUIRES A MANUAL LOCAL RESET VIA RED BUTTON DEPRESSION.15. FOR CIRCUIT BREAKERS BUILT AFTER JULY 2006 AND DIGITRIP 1150 UNITS OF FIRMWARE REV 20decimal OR GREATER,THE MAINTENANCE MODE FEATURE (ARMS) IS SUPPLIED. THE REVERSE POWER DESELECTIONS FRONT PANEL PRO-GRAMMABLE ONLY.www . ElectricalPartManuals . com
