Tripping Cause

The tripping cause register provides information about the cause of the trip for the standard protection functions. When a tripping cause bit is at 1 in the tripping cause register, it indicates that a trip has occurred and has not been reset.

For MicroLogic A/E trip units for ComPact NSX circuit breakers, the tripping cause bit is reset by pressing the OK key (keypad of the MicroLogic A/E trip unit) twice (validation and confirmation).
For MicroLogic A/E/P/H trip units for MasterPact NT/NW and ComPact NS circuit breakers, the tripping cause bit is reset as soon as the circuit breaker is closed again.
For MicroLogic X control units for MasterPact MTZ circuit breakers, the tripping cause bit is reset by pressing the test/reset button (located beside the trip cause LEDs on the MicroLogic X control unit). Press and hold the button for 3 to 15 seconds to reset all the trip causes.
