AN IMPROVED MOVING CONTACT SHIELD CONSTRUCTION FOR DOUBLE BREAK CIRCUIT BREAKERS

摘要

The present invention provides an improved moving contact shield construction for double break circuit breakers. The moving contact assembly comprises a rotor comprises at least one moving contact for forming a rotary actuating arrangement; a moving contact shield for providing insulation to the moving contact; and a spring chamber for maintaining contact pressure in the assembly. The moving contact shield provides isolation to the moving contact from the arc and arcing product(s) during arching in the circuit breaker.
