The YCM7-125S and YCM7-160S MCCB 100A Circuit Breakers are premium molded case circuit breakers designed for industrial and commercial power distribution. Compliant with IEC60947-2, these breakers deliver robust protection against overloads, short circuits, and undervoltage conditions. With compact designs and versatile configurations (3P/4P), they are ideal for applications requiring reliable 100A-rated protection.

YCH9s-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.

Product standard:IEC600947-3

The AFDD Arc Fault Detection Device is a critical safety solution engineered to mitigate electrical fire risks in residential, commercial, and industrial environments. By combining arc fault detection, residual current protection, and overload/short circuit safeguards, it offers comprehensive defense against common electrical hazards. With four adjustable sensitivity modes, it adapts to diverse settings—from homes to factories—while intuitive indicators and a test button ensure ease of monitoring and maintenance. Its modular DIN rail design simplifies installation, making it an essential upgrade for modern electrical systems.

This automatic reactive power compensation controller.It is suitable for automatic regulation of capacitor compensation device in low voltage distribution system (hereinafter referred to as controller).It makes the power factor reach the user’s predetermined state, improves the utilization efficiency of the power transformer, reduces the line loss, and improves the voltage value of the power supply, so as to improve the economic and social benefits.

General
YCQ9E series automatic transfer switch, rated working curent 16A to 630A,to be used in pow- er systems for ensuring the continuity of the supply, by transfering a load between two power supply sources. The switch has three working posions of “Main ( I ) cosing”, “Standby ( II )
closing” and “Double-of (0)”, which can be used for fire-fighting linkage and infrequent con-
necion and disconnecion of power supply systems. Mainly used in hospitals, shopping malls, banks, chemical industy, metalurgy, high-rise buildings, military facilities and fire-fighting occa- sions where power failure is not allowed.
Standards: IEC 60947-6-1

General
CJ19i contactor for capacitor switching (hereinafter called contactor)is suitable forthe circuitofAC 50Hz/60Hz with rated rated voltage up to 690V.It is mainly used toadd low voltage reactive power compensation equipment or cut off low voltageparalel capacitor.The contactor is equipped with a device to suppress the inrushcurrent,which can effectively reduce the impact ofthe making inrush current on thecapacitor andsuppress the over-voltage when thecapacitor is cut off.Standard:IEC/EN 60947-4-1.
