  1. 1
    • Master element: normally used for hand-operated devices. A common use is the spring-return-to-center control switch for circuit
    • breakers, where the switch contacts are lOlT (trip), lOlc (close), lOlSC (closed when turned to close and remains closed when released, opens when turned to trip and remains open when
    • released). When several breakers are involved, they are identified by 101, 201, 301, and so on.
