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 circuit breaker has the characteristics of reliable performance, high breaking capacity, beautiful and compact appearance, etc., especially it can accurately detect the voltage, breaker take action when the circuit breaker exceeds the normal voltage range value.
