JK24L-63 series small circuit breaker
Short Description:
The JK24L series leakage circuit breaker has the characteristics of advanced structure, reliable performance, high breaking capacity, and beautiful and compact appearance. shell and main components are made of impact-resistant and high-flame-retardant materials. It is suitable for places with an alternating current of 50Hz or60Hz, a rated working voltage of 400V and below, and a rated current of 6A to 63A. It is mainly used for overload, short circuit, and leakage protection of lighting, distribution lines, and equipment in office buildings, residential buildings, and similar buildings. It can also be used for infrequent switching lines under normal conditions.
