YCM9LZ Earth Leakage Circuit Breaker


  • Product Overview
    YCM9LZ series residual current operation circuit breaker(shortened as auto reclosing) is a newly-developed new-generation integrative multi-functional product which adopts patent technology and conforms to all intelligent requirements of state grid administration. It’s the priority product to cooperate with China National Grid.
    When the circuit breaker trips because of Temporary earth leakage or instantaneous earth leakage or voltage fault caused by electric surge, the power can be restored directly through self re-closing function without manual operation. The circuit breaker can be installed vertically as well as horizontally.
