CPS

1. What Is An Control and Protective Switching ?

A Control and Protective Switching Device (commonly abbreviated as “CPS”) is an integrated, multi-functional low-voltage electrical appliance. Its core function is to integrate the functions of multiple discrete components in traditional low-voltage power distribution systems, such as “circuit breakers, contactors, overload protectors, and isolation switches”, into a single unit. It achieves the dual functions of “control” and “protection” for electrical circuits, and is widely used in the fields of low-voltage power distribution and motor control.

2. HOW Control and Protective Switching Work ?

The core operation of a Control and Protective Switching Device (CPS) revolves around the principle of “Real-time Monitoring – Intelligent Judgment – Precise Execution”. Through its internally integrated circuit modules, mechanical structures, and protective components, it simultaneously achieves both “electrical circuit on/off control” and “fault risk prevention”. It not only replaces the “control” role of traditional contactors but also undertakes the “protection” responsibilities of devices such as circuit breakers and thermal relays.

3.Application Scenarios of Control and Protective Switching Devices (CPS)

With its core advantages of “integrated control + multiple protections”, the Control and Protective Switching Device (CPS) is suitable for various scenarios in low-voltage power distribution systems that “require simplified circuits and improved reliability”. It is particularly widely used in fields with high requirements for electrical safety and equipment stability. Its main application scenarios include motor control and protection scenarios (industrial drive motors, civil/commercial motors, special-purpose motors) andpower distribution circuit control and protection scenarios, among others.
