Project Description

GV2 Motor protection breaker

GV2-ME motor protection circuit breaker switch sizing

GV2-ME motor protection circuit breaker switch sizing is suitable for circuits the alternating voltage up to 690V, current up to 80A. The product works to control the overload, phase loss, short circuit protection and infrequent starts of a three-phase squirrel cage asynchronous motor. The motor Starter can protect the distributing line for infrequent load transfer and it can also works as an isolator.
