ARRANGEMENT OF PROTECTIVE INTERFACE IN CIRCUIT BREAKER

摘要

The present invention provides a double interface arrangement which utilize less space to provide IP even with higher angular travel of knob. Two interfaces along with the knob cover the entire area of opening space created during switching of breaker and provide IP. The arrangement comprises an ingress protection assembly comprises a first cover having at least one projection and a second cover having at least one slot; a front cover having at least one projection for sliding the ingress protection assembly. The movement of the ingress protection assembly along angular movement of a knob of the circuit breaker covering the opening space created during switching of the circuit breaker, thereby providing ingress protection to the circuit breaker.
