Présentation du produit

QJL7-63 Miniature Circuit Breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit. Its basic function is to interrupt current flow after a fault is detected. They are common in domestic, commercial and industrial applicationIt also can be used for non-frequent on-and-off switching operations under normal circumstances.
