Electronic circuit breaker, electronic circuit breaker subassembly, circuit breaker secondary electrical contact assembly, and powering methods

摘要

Embodiments provide an electronic circuit breaker subassembly and circuit breaker secondary electrical contact assembly. The circuit breaker secondary electrical contact assembly has a main contact terminal connectable to a main power terminal, a secondary electrical contact set having a stationary secondary electrical contact and a moveable secondary electrical contact, a lockout conductor provided in spring-engaged contact with the main contact terminal on a first end and including one of the stationary or moving secondary electrical contacts on a second end, and a spring having the moveable secondary electrical contact provided on a moveable portion. Circuit breakers and methods of operating the electronic circuit breaker are provided, as are other aspects.

主权项

1. An electronic circuit breaker subassembly, comprising:
a housing; a main contact terminal connectable to a main power terminal; a secondary electrical contact set having a stationary secondary electrical contact and a moveable secondary electrical contact; a lockout conductor provided in spring-engaged contact with the main contact terminal on a first end and including one of the stationary or moving secondary electrical contacts on a second end; a spring having the moveable secondary electrical contact provided on a moveable portion; and a handle moveable between at least an ON configuration and an OFF configuration, the handle configured and operable to cause motion of the moveable portion and cause engagement of the moveable secondary electrical contact and stationary secondary electrical contact; wherein: the main contact terminal, the secondary electrical contact set, the lockout conductor, the spring, and the handle are configured to form a current path to power an electronic circuit capable of performing a self test of an electronic circuit breaker.
