Selection Of Intelligent Circuit Breakers

When the intelligent universal circuit breaker is used as electrical equipment or line protection, the user should consider the following four points when selecting models:

(1) The rated current of the selected circuit breaker is greater than or equal to the rated current of the line or electrical equipment;

(2) The rated short-circuit breaking capacity (current) of the selected circuit breaker is greater than or equal to the expected (maximum) short-circuit current of the line;

(3) The protection function of the selected circuit breaker is relatively complete and comprehensive, which can meet the requirements of its work environment;

(4) The size of the circuit breaker is relatively small, which saves space, and the intelligent circuit breaker is convenient to install multiple circuit breakers in the same cabinet.
