Circuit breaker with improved trip means |
摘要 |
A circuit breaker comprises a stored-energy mechanism and a resettable roller-type latch for latching the stored-energy mechanism. The latch is operable upon the occurrence of overload current conditions to release the stored-energy mechanism to thereby trip the breaker. Alternately the latch may be actuated by utilizing a separate switch.
