Miniature circuit breaker, also known as miniature circuit breaker, is suitable for overload and short circuit protection of lines with AC 50/60Hz rated voltage of 230/400V and rated current up to 63A. It can also be used for infrequent operation and switching of lines under normal conditions.

Miniature dc circuit breaker is an important product of low-voltage switchgear. it is used to control infrequently making and breaking current in ac 50 hz circuit. it has the advantages of small size, compact structure, convenient operation and so on.

The small leakage circuit breaker is a current limiting circuit breaker with overload and short circuit protection, which is applicable to the overload and short circuit protection of industrial and commercial lighting distribution systems with AC 50Hz, single pole voltage of 230V and below, and two, three and four pole voltage of 400V and below. It can also be used for infrequent on-off switching of lines under normal conditions.
