    An electrical device that opens and closes a circuit; it may be manually operated, automatically operated by some other electrical circuit, or operated by the change in some physical condition such as flow, level, or temperature. switched reluctance motor A motor that relies on induced magnetism in salient poles, instead of a rotor winding.

  5. Reference designator - Wikipedia

    en.wikipedia.org/wiki/Reference_designator

    A reference designator unambiguously identifies the location of a component within an electrical schematic or on a printed circuit board.The reference designator usually consists of one or two letters followed by a number, e.g. C3, D1, R4, U15.

  6. Integrated gate-commutated thyristor - Wikipedia

    en.wikipedia.org/wiki/Integrated_gate-commutated...

    The very high gate currents and fast dI/dt rise of the gate current mean that regular wires can not be used to connect the gate drive to the IGCT. The drive circuit PCB is integrated into the package of the device. The drive circuit surrounds the device and a large circular conductor attaching to the edge of the IGCT is used.

  7. Circuit breaker - Wikipedia

    en.wikipedia.org/wiki/Circuit_breaker

    A circuit breaker is an electrical safety device designed to protect an electrical circuit from damage caused by current in excess of that which the equipment can safely carry (overcurrent). Its basic function is to interrupt current flow to protect equipment and to prevent fire .
