The frame-type intelligent circuit breaker can be regarded as the "safety manager" in the distribution network. It is suitable for AC 50Hz and rated voltage (commonly 400V/690V) circuit environments. Its core function is to rationally distribute electrical energy and provide targeted protection for circuits and electrical equipment. When encountering problems such as overload, short circuit, under-voltage, and ground fault, it will act promptly to prevent the expansion of faults. With an intelligent controller and manual/electric dual operation modes, it can also monitor the operating status and adjust protection parameters. It is widely used in distribution scenarios such as industrial plants, commercial buildings, and power facilities.

Intelligent protection is more precise

Equipped with a digital controller, it can set protection parameters such as overload long delay and short-circuit instantaneous as needed. The screen displays current, voltage and other data in real time, and the fault alarm is timely. The "sense of proportion" in protecting equipment and circuits is very good.

Safety performance is maximized

Multiple protections such as overload, short circuit and undervoltage are superimposed. Coupled with a solid structure and strong arc extinguishing ability, the ability to break fault current is reliable, significantly reducing circuit hazards.

The operation is very easy

Clear opening/closing buttons + status lights. The controller interface is intuitive and easy to understand. It supports both manual and electric modes, making daily debugging and status monitoring effortless.

The application scenarios are wide-ranging

There are different rated current models, which can meet the needs of different power distribution capacities; the multiple sets of terminals at the top can also be connected to the automation system, meeting the requirements of intelligent power distribution.
