ELECTRICAL SWITCHING APPARATUS AND PUSH-TO-TRIP ASSEMBLY THEREFOR |
摘要 |
A push-to-trip assembly is provided for an electrical switching apparatus, such as a circuit breaker. The push-to-trip assembly includes a push-to-trip actuator having first and second ends and being movable among a first positi on corresponding to the circuit breaker separable contacts being closeable, and a second position corresponding to the second end cooperating with a trip bar to caus e the circuit breaker operating mechanism to trip open the separable contacts. The first end is accessible from the exterior of the housing to actuate the push-to-trip actuator from the first position to the second position. A biasing element biases the push - to-trip actuator away from the base toward the first position. At least one cover st op of the push-to-trip actuator engages a corresponding portion of the housing cover t o stop movement of the push-to-trip actuator. An overtravel restraint proximate the second end of the push-to-trip actuator restrains movement of the trip bar.
