BM-63 series miniature circuit breakers、BM-63/S series miniature circuit breaker with short circuit protection only、BM-63G Series with over current protection series miniature circuit breaker with over current protection and over voltage protection
BM-63 series miniature circuit breakers are characterized by advanced structure, reliable performance, high breaking capacity, beautiful and compact appearance, etc. The shell and three parts are made of impact resistant and high flame retardant materials. Applicable to ac 50Hz/60Hz, rated working voltage 230V/400V, rated current to 63A line, used for building and similar places of the line facilities and electrical equipment for over-current and short-circuit protection, can also be used for infrequent on-off operation, bm-63 circuit breaker is suitable for non-professional use and does not require maintenance.
BM-63G series miniature circuit breakers add overvoltage protection function on the basis of bm-63.
BM-63 /S series miniature circuit breaker is a special circuit breaker with short circuit protection only and no overload protection. It is used in special occasions. Its external dimensions and basic parameters are the same as those of bm-63.
