GY88 intelligent display circuit breaker device is our company in accordance with the needs of the development of urban power grid, adding an updated function protection products. Is the latest comprehensive intelligent display integrated protection device, which integrates leakage relays, circuit breakers and transformers in one of the full function protection device. The product has intelligent selection protection, convenient parameter setting, and RS485 open communication interface with remote transmission function. The utility model has the advantages of reasonable structure, reliable breaking and convenient installation. The utility model is mainly applicable to the protector for the leakage, overload, short circuit, overvoltage, undervoltage and phase interruption in the low-voltage distribution system of three-phase four wire supply equipment. In order to prevent personal shock, equipment failure or electrical fire, etc., the best ideal protection products.

This product functions and features

The intelligent circuit breaker with function, but also for rated current and short circuit breaking time. It has high breaking capacity and short arc distance.
