 YKM1 series of molded case circuit breaker (short for circuit breaker), is the latest circuit breaker of advanced technology. The insulation voltage is 800V, (YKM1-63: 500V), used for the circuit of rated working voltage 690V and below, (YKM1-63: 400V), rated working current 800A to infrequently transfer and infrequently starting. The circuit breaker have the functions of overload, short circuit and undervoltage protection which can protect the circuit and power equipment from damage.

Circuit breaker can be classified as L type (standard), M type (comparative higher breaking), and H type (higher breaking). The circuit breaker are small-sized, high breaking capability, short arc, anti-shake, it is the ideal products for land and shipping.

The circuit breaker can be vertically installed or level installed. Only 1,3,5 connect to the power line, 2,4,6 connects to load line

The circuit breaker have the function of isolation.

Standard: IEC60947-1 and GB/T14048.1 General

        IEC60947-2 and GB14048.2 LV circuit breaker

        IEC60947-4 and GB14048.4 contactor and motor starter

        IEC-60947-5.1 and GB14048.5 motor type control circuit electric apparatus
