    VKM1 series of molded case circuit breakers are applied to frequently changeover the circuit of rated insulation voltage of 800V (VKM1-63 is 500V), AC 50/60Hz, rated voltage 690V or below (VKM1-63 is 415V), rated operating current 1250A, or start the motor not frequently (VKM1-800 without motor protection). The breakers provided with overload short-circuit and under-voltage protection function to protect the lines and power equipment from damage.

    The product can be mounted vertically or horizontally.
