WHKB1-63 series high breaking mini circuit breaker has the characteristics of advanced structure, reliable performance, high breaking capacity, beautiful and compact appearance. The shell and three parts are made of impact-resistant and high flame retardant materials. It is suitable for places with AC 50Hz or 60Hz, rated working voltage below 400V and rated current below 63A. It is mainly used for lighting of office buildings, residential buildings and similar buildings, overload and short-circuit protection of distribution lines and equipment, and can also be used for infrequent line conversion under normal circumstances.
