    摘要: A circuit breaker contact position indicator is mounted on the same support platform as the circuit breaker electronic trip unit and contains a micro-switch to provide indication to the trip unit of the status of the circuit breaker contacts. The switch interacts with the circuit breaker operating mechanism crossbar cam by means of a spring-loaded paddle attached to the trip unit support platform.
