Circuit-breaker with fixed and moving contact with drive monitored by light barrier

摘要

The light paths (8, 10, 12, 14:9, 11, 13, 15) are blocked or are opened by a moving switch unit, in the course of the ON and OF movement of the circuit breaker. So that using the light barrier, the switch settings of the circuit breaker can be determined. Whether the ON or the OFF position of the circuit breaker is reached, and the circuit breaker has a sensor, for determining the position of the drive and a unit (16, 17), which accepts the signals related to the switching position, emanating from the sensor.
