Low Voltage Circuit Breaker

Our company is dedicated to producing various low voltage circuit breakers (less than 1000 VAC). Miniature circuit breakers and molded case circuit breakers are our main low voltage circuit breaker products.

MCB (Miniature circuit breaker) is a thermal-magnetic breaker whose rated current is less than 100A. Normally, its trip characteristics are nonadjustable. MCCB (Molded case circuit breaker) also is a thermal-magnetic breaker with rated current up to 2500A. Its trip current is adjustable.

Our low voltage circuit breaker is widely used in factories, commercial buildings and residential houses. It is always installed in draw-out enclosures of low voltage switchboards or switchgear cabinets.

Huayi Electric Co., Ltd. is an experienced low voltage circuit breaker manufacturer based in China. Founded in 1986, we constantly strive for providing our customers with high quality power transmission and distribution equipment, circuit breakers, load break switches, disconnect switches, indoor vacuum circuit breakers, etc.
