  • [ Descriptions ]

    AX, Auxiliary Switch

    It gives ON/OFF signal of the breaker with a changeover contact.

    AL, Alarm Switch

    It gives TRIP signal of the breaker.

    It does not operate when the breaker is normally opened or closed.

    It consists of a changeover contact.

    SHT, Shunt Trip device

    It make the breaker TRIPPED when any AC or DC voltage

    is applied to itself.

    UVT, Under Voltage Trip device

    It make the breaker TRIPPED when the control voltage disappears or falls.
