Scope of application
The GM5-63 small DC circuit breaker adopts a special arc extinguishing and current limiting system, which can quickly break the fault current of the DC distribution system, greatly improving the level difference coordination. This series has excellent performance and can avoid the occurrence of accidents such as over level tripping between the measurement and protection screen and the distribution screen in the DC system of power engineering. The differential matching characteristics of this series of products are the best among similar products at home and abroad.

The GM5-63 series small DC circuit breaker complies with GB10963.2-2003 "Overcurrent Protection Circuit Breakers for Household and Similar Places Part 2: Circuit Breakers for AC and DC", and is suitable for single pole rated DC voltage not exceeding 220V, two pole rated DC voltage not exceeding 440V, rated current 1-63A, and rated insulation voltage 500V lines. It is used for overcurrent protection of buildings and similar places' line facilities, and can also be used for infrequent on-off operations. This circuit breaker has the characteristics of small size, high breaking capacity, short arcing distance, fast closing, and easy installation. This product is suitable for non professionals to use and does not require maintenance.
