CMH3LE-63 series small earth leakage circuit breaker is suitable for AC frequency 50Hz, rated working voltage AC240V/AC400V, rated working current up to 63A and below in the distribution line, when personal electric shock or grid leakage current exceeds the specified value, the earth leakage circuit breaker can quickly cut off the faulty power supply in a very short time to protect the safety of personal and electric equipment. CMH3LE-63 series small earth leakage circuit breaker has advanced structure, reliable performance and the shell is made of impact resistant and high flame retardant material. It is mainly used for overload, short-circuit and leakage protection of lighting, distribution lines and equipment in office buildings, residences and similar buildings, and can also be used for infrequent conversion of lines to start under normal conditions.
