AI Customer ServiceOpen the circuit breaker by pressing the opening switch . o The contact position indicator (D) changes to O (OFF). o The charge indicator (E) stays on discharged. Reset the circuit breaker: recharge the stored energy control by operating the charging handle (8 times). o The contact position indicator (F) stays on O (OFF).
Page 20 Circuit breaker operation 2.6 Locking the circuit breaker in the OFF position using keylocks Action Illustration (continued) The push button returns to its initial position. Check that it is now possible to close the circuit breaker by pressing the closing push button ATTENTION The key cannot be removed in horizontal position.
Open the circuit breaker by sending an open (OFF) command. o The contact position indicator (C) changes to O (OFF). o The charge indicator (D) stays on discharged. o The contact position indicator (E) stays on O (OFF). o The charge indicator (F) changes to charged.
The motor mechanism can open and close the circuit breaker remotely with electrical commands. Do not modify the wiring diagrams for the motor mechanism. Failure to follow these instructions can result in injury or equipment damage. Wire the motor mechanism in strict accordance with the motor mechanism wiring diagram in the Appendix.
Move the selector to the Manu position. Cycle of operation: Check that the spring-charged indicator is on charged (A). If not, reset the circuit breaker. Close the circuit breaker by pressing the closing pushbutton . o The contact position indicator (B) changes to I (ON). o The spring-charged indicator (C) changes to discharged.
Isolate the feed before inspecting the downstream electrical equipment. With selector on Manu, operate the charging handle 8 times to reset the circuit breaker in ready-to-close position. Result: The spring-charged indicator changes to charged (B) and the internal mechanism goes from the Trip position to the O (OFF) position (A).
