Tripping device in case of undervoltage having an early auxiliary switch for a circuit breaker

Purpose: use a trigger mechanism in the event of existing undervoltage, conforming to specifications of standards having an early auxiliary switch as a base while changing only a portion of the internal wiring of the device to improve the device and allow the implementation of various câblage.Dans processes a triggering device in case of undervoltage having an early auxiliary switch for a circuit breaker, device that is installed on one side of a circuit breaker 1 and which comprises a trigger mechanism in case of undervoltage and early auxiliary switch 14 incorporated in an 11-unit housing, the trigger mechanism in the event of an undervoltage comprising a combination of an electromagnet 13 and a trip lever 15 of the early auxiliary switch opening and closing a conductive path for a connection solenoid with the operation of a Poiger born 5 of the circuit breaker, and terminals 12a to 12d of the external connection located at each of opposite ends of the housing, the housing being shaped to fit the outer frame of the circuit breaker main body, wiring circuits for the solenoid and wiring circuit for early auxiliary switch being separated from one another in the unitary housing, early auxiliary switch being connected between the external connections of the connection housing, and the electromagnet comprises coil conductors 13b which are drawn directly from the housing and are connected to external wiring.
