Intelligent Universal Fixed Circuit Breaker

Ceho, as a professional R&D and manufacturing factory of Intelligent Universal Fixed Circuit Breaker in China, specializes in mass production, strict ISO quality control and OEM/ODM service. Circuit breakers with a rated current of 1000A and above can also be used in AC 50Hz, 400V power grids as overload, short circuit, undervoltage, and ground fault protection devices for motors. Under normal circumstances, they can be used for infrequent motor starting. This product features fixed installation and integrated intelligent trip unit, making it widely used in industrial power distribution, buildings, power plants, and other applications to achieve power distribution, line protection, and remote monitoring.

This circuit breaker employs precise protection and a multi-functional intelligent controller, providing comprehensive protection functions. It is particularly suitable for power distribution networks requiring improved power supply reliability and avoidance of unnecessary power outages. The H-type intelligent controller has a communication interface, allowing easy connection to a fieldbus to achieve four remote functions: "telemetry," "remote adjustment," "remote control," and "remote signaling," meeting the requirements of control automation. Leakage protection can be achieved by configuring a leakage current transformer and a corresponding intelligent controller.
