HGB3L-63 series small residual current circuit breaker is applicable to distribution lines with rated frequency of 50Hz, rated working voltage of AC240/AC400V and rated working current of 63A and below. When personal electric shock or grid leakage current exceeds the specified value, the residual current circuit breaker can quickly cut off the fault power supply in a very short time to protect the safety of personnel and electrical equipment. Conforming standards: GB/T16917.1, IEC61009-1. HGB3L-63 series small residual current circuit breakers are advanced in structure, reliable in performance, compact in size, and made of impact resistant and high flame retardant materials. HGB3L-63 series small residual current circuit breakers have overload, short circuit and leakage protection functions. They are mainly used for overload, short circuit and leakage protection of lighting, distribution lines and equipment in office buildings, residential buildings and similar buildings, and can also be used for infrequent switching and starting of lines under normal conditions.
