ABSTRACT:
The trip bar is sub-divided into a first actuating part associated to the trip rod of the actuator and a second actuating part operating in conjunction with the indicating device. A mechanical coupling link is arranged between the two actuating parts being adjustable between a coupled position and a disengaged position. An operating lever performs locking of the second actuating part in the active position to keep the fault information on the indicating device, whereas the first actuating part returns automatically to the inactive position when said mechanical link is in the disengaged position.
