Circuit Breaker

A circuit breaker is a kind of electrical switch, designed to protect an electrical circuit from damage caused by short circuit or overload. It is basically used to detect a fault condition and immediately discontinue electrical flow, by interrupting continuity. Due to different applications, circuit breakers can be divided into different types, such as high voltage circuit breaker, low voltage circuit breaker, vacuum circuit breaker, electrical circuit breaker, oil circuit breaker, etc.

We are a professional circuit breaker manufacturer in China, committed to manufacturing residual current circuit breaker, residual current device, earth leakage circuit breaker, etc. They have high capacity, easy operation, high safety, and short circuit protection function as well, and are mainly suitable for using in varieties of plants, enterprises, buildings, constructions, commerce, hotels and families.

Besides, electric switch, circuit breaker, thermostat and current transformer are also supplied by us. Thanks to superior quality and lower prices, we have exported our products to America, Britain, Germany, France, and so on. We can also provide OEM service. Welcome you to try our products!
