We provide key manufacturing processes including spot welding, riveting, and assembly, all performed in accordance with customer requirements.

External accessories for molded case circuit breakers are externally mounted actuators that enable remote, automated, and intelligent control, as well as information-based, systematic management of the circuit breaker. These accessories include manual operating mechanisms, motorized operating mechanisms, plug-in devices, and withdrawable devices.

KYW3 series universal circuit breakers are suitable for AC power distribution networks at 50/60Hz, with rated current from 200 to 4000A, rated insulation voltage of 1000V, and rated operational voltage of 400V/690V AC.

They distribute electrical energy and protect circuits and equipment from overload, undervoltage, short-circuit, single-phase ground faults, and other hazards, while also providing isolation. Featuring multiple protection functions, they support selective protection to reduce unnecessary power outages and enhance the reliability and safety of the power supply system.

We can develop and design custom solutions to meet your specific requirements.

The internal accessories of a Molded Case Circuit Breaker (MCCB) are actuator mechanisms integrated within the breaker, designed to enable remote operation, automation, intelligent control, as well as information-based and systematic management of the circuit breaker.

These accessories fall into the following categories:Undervoltage Release (UVR)、Shunt Release (SHR)、Auxiliary Contact (AX)、Alarm Contact (AL)、Combined Auxiliary & Alarm Contact.

We specialize in the R&D and production of flexible conductive connectors, which fall into two core categories: copper foil flexible connectors and braided wire flexible connectors. These products offer high flexibility, reliable current-carrying capacity, and low contact resistance. Custom sizes and conductivity specifications can be tailored to meet customer requirements.

Using copper and copper alloys as primary materials, we also provide custom precision machining services for a wide range of components, including profiles, busbars, arc chutes, bar contacts, copper rods, and moving/static contacts. Our parts feature high machining accuracy, stable conductivity, and stable mechanical strength.
