Circuit Breaker

SYHF Electric has a core team of experts and technical backbones with rich industry experience and outstanding performance. The company's Circuit Breaker is an important electrical safety device, mainly used to prevent equipment damage or fire hazards caused by overcurrent or short circuit.

Its basic principle is to quickly interrupt the flow of current after the protection relay detects an electrical fault, thereby cutting off the source of the fault. Unlike fuses that can only be used once, circuit breakers can be reset and power restored manually or automatically after tripping, with the advantages of repeated use and convenient operation.

Circuit Breakers are widely used in power systems such as distribution boards and switch cabinets. They can be used as overload protection devices, and are often used as main switches to manually disconnect and connect electricity in a certain area, realizing effective management and safe control of power grid subsystems. Whether in household electricity, industrial loads, or in high voltage systems in large substations, circuit breakers play a key role in electrical protection.
