Enclosed Circuit Breaker 630A 3P

Enclosed Circuit Breaker 630A 3P are devices used in low-voltage distribution systems to protect electrical circuits and equipment, integrating overload, short-circuit and protection functions. The circuit breaker housing is made of high-strength flame-retardant plastic, which has good insulation and arc resistance. The product is equipped with an electromagnetic and thermal dual trip structure inside, which can achieve rapid disconnection within milliseconds when an electrical fault occurs. This can effectively prevent equipment damage and fire risks caused by electrical circuit overload and short circuit.

Product details

The product adopts a modular structure design and supports standardized rail installation. It has a compact overall volume and is convenient for integration. The contact system of the product is made of silver alloy material and features an optimized arc-extinguishing structure design, which enables the product to have a high breaking capacity and a long electrical life.

1.This product adopts a tripping operation handle and uses a connecting rod structure design to reliably achieve the connection and disconnection operations of the product.

2. This product adopts copper coin terminal blocks and purple copper galvanized contacts, which have better electrical conductivity and safer circuit connection.

Product application
