Molded case circuit breaker modular contact arm arrangement |
摘要 |
A molded case circuit breaker movable contact arm electrically connects with the circuit breaker load terminal by means of parallel electric paths provided by a looped braid conductor. The contact arm support includes a single support leg for pivotally retaining the movable contact arm on one side. The opposite side of the contact arm is supported on the operating mechanism crossbar. Contact arms of increasing thickness are used to accommodate the higher transport currents required with circuit breakers of increased ampere ratings.
