PSDV2(GV2) Motor Protection Circuit Breaker
GENERAL
PSDV2(GV2) series motor protection circuit breaker, uses the modular design, the contour is artistic, the volume is small, breaks protects, inside sets thermal relay. The function is strong, the versatility is good.
PSDV2(GV2) series motor protection circuit breaker is suitable for circuits with AC 50/60Hz, rated working voltage up to 690V, and current ranging from 0.1 to 80A. It is used for overload, phase-failure, short circuit protection, and infrequent start control of three-phase squirrel cage asynchronous motors. It can be used for distribution line protection and infrequent load switching, and also as an isolator
