Product Description
Customized Molded Miniature Case Conventional Mini Circuit Breaker
Standard: IEC/EN 60947-2

YCM3 series moulded case circuit breaker (hereinafter called MCCB) is a new generation of breaker. This MCCB is suitable for the circuit of AC 50Hz/60Hz with rated insulation voltage 1000V (800V for frame size of 125) and rated service current between 63A and 630A. It is mainly used to distribute electric energy and protect circuits and electric equipment against over-load, under-voltage, short-circuit and earthing fault.
