MCB has the characteristics of advanced structure, reliable performance, high breaking capacity and beautiful appearance. It is mainly used for AC 50HZ or 60HZ, rated voltage 240/415V or below and rated working current 63A or below. It is used for overload and short-circuit protection of lighting, distribution lines, equipment in office buildings, residential buildings and etc. It can also be used for infrequent on-off operations and conversion of lines.
