Item Name: GTM9 series Mould Case Circuit Breaker
The breaker is mainly used in distribution network of AC 50Hz or 60Hz, rated voltage up to 690V, rated working current up tp 630A to distribute electric power and to protect the line and the equipment from being damage due to overload, Short circuit and under-voltage. It can also be used fro unfrequent motor start and for motor overload, short circuit and under voltage protections.
Standard: IEC 60947-2
