AC Circuit Breaker

DZ47-63 Miniature Circuit Breaker

H-Power's DZ47-63 AC circuit breaker complies with IEC60898 and GB10963 standards. Suitable for applications with AC 50HZ or 60HZ, 400V or less rated voltage, and 63A or less rated current, the miniature circuit breaker is used for overload and short circuit protection in lighting, power systems, and appliances and equipment in homes, office buildings, and other commercial buildings. The mini circuit breaker can also be used for infrequent on-off circuits and conversion. The AC breaker has a high breaking capacity and a small size--only 18mm in width. It can cut live wires and neutral wires at the same time, preventing the chance of fire, and is the best distribution protection switch for residential areas.
