Abstract

A circuit breaker comprises a stored-energy mechanism and an improved resettable roller-type latch means latching the stored-energy mechanism. The latch means is operable upon the occurrence of overload current conditions to release the stored-energy mechanism to thereby trip the breaker. The latch means may also be manually operated to trip the breaker.
