BM-50L series small leakage circuit breakers, BM-50LG series with overvoltage protection leakage circuit breakers
BM-50L series miniature residual current circuit breaker is suitable for AC 50 Hz, rated voltage to 230 V / 400 V, rated current to 50 a power supply lines, to protect lines and electrical equipment overload and short circuit. Leakage circuit breaker is used for leakage protection, and its leakage tripping mode is electronic, which is mainly composed of zero sequence current transformer, electronic component board and circuit breaker.
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-63GQ series miniature circuit breakers with over current, over voltage and under voltage protection
BM-63GQ series mini-circuit breakers with over-current, over-voltage and under-voltage protection are suitable for ac 50Hz/60Hz, rated working voltage 230V/400V, rated current up to 63A power supply lines.When the line voltage is greater than 275 (±- 5%)V or less than 160 (± - 5%)V, and when the line facilities and electrical equipment over current or short circuit protection, can also be used for infrequent combined operation.
BM-63GQ /2P series miniature circuit breakers with over-current, over-voltage and under-voltage protection (small case)
BM-63GQ/2P series mini-circuit breakers with over-current, over-voltage and under-voltage protection (small cases) are suitable for ac 50Hz power supply lines with rated working voltage of 230V and rated current of 6-63a.When the line voltage is greater than 275V, less than 160V, the tripper makes the assembled tripping, protect the electrical equipment.It is characterized by small volume, accurate, stable and reliable detection line voltage.
