Product Description

Moulded Case Circuit Breaker

Application and range of application
Our MCCB uses the international advanced design, one of the technique of manufacture developement,development new circuit breakers, Its fixed isolation voltage is 690V, is suitable in exchanges 50Hz, fixed working volage 400V and below. Rated current to 800A circuit as frequent changeover gun less frequent motor starter. The Circuit breaker with overload, short circuit protection device, and less voltage protection circuit and power equipment are not damaged.
