GTW1 series air circuit breaker is applicable for distribution network with AC 50Hz, rated voltage 690V and below, rated current 200A to 6300A, to distribute electric enegry protection circuit and prevent power equipment from harm of overload, under voltage, short circuit and single phase earth. GTW1 series air circuit breaker has intelligent protection function, precise selective protection, can improve the depehdability of power supply and avoid unwanted power cut. At the same time with an open communication interface, "four remote" can be performed to meet the requirements of the control center and the automation system. The circuit breaker does not have an intelligent controller and a sensor can be used as an isolator.
