How to select the circuit breaker that meets your requirements

With the development of science and technology, moulded case circuit breaker has become an indispensable part of electrical system. They can effectively protect electrical systems from overload, short circuit and other potential hazards. Therefore, it is very important to select a suitable moulded case circuit breaker.

When choosing a moulded case circuit breaker, the first thing to consider is the type of circuit breaker. According to the different requirements of the electrical system, different types of circuit breakers can be selected. From the trip unit type, it can be roughly divided into current fixed circuit breakers and current adjustable circuit breakers.

CEZC circuit breakers produced by our company belong to current fixed circuit breakers, while CNS, CNSX and CNSV belong to current adjustable circuit breakers.

Second, we should consider the specifications of the circuit breaker. Circuit breaker specifications include voltage, current, and breaking capability. You must select the appropriate circuit breaker specifications based on the actual requirements of the electrical system.

The rated operation voltage of our CNS and CNSX is 690VAC, the voltage of CNSV is 440VAC, the current range of our CNS type circuit breaker is 630-1600A, while the current range of the CNSX and CNSV type circuit breaker is 16A-630A.

Selecting a suitable moulded case circuit breaker is very important to protect the electrical system from danger. When selecting a circuit breaker, select an appropriate type and specification based on the actual requirements of the electrical system.
