  • Application

    YCH9-125 series isolating switch is suitable in the resistive circuit of AC 50/60HZ,
    rated voltage 230/400V, rated current up to 125A. It's used primarily for circuit's
    turning on or off in non-load ed situation. And it functions on connection and
    isolation between lines and power, especially suitable to isolate power effectively and
    prevent circuit breaker from closing accidentally when maintain the circuit in order to
    ensure the safe operation of maintainer.
