LR1-D Thermal relay

Application

LR1-D series themral relay is suitable for using in the circuits rated voltage up to 600V, rated current 93A AC 50Hz or 60Hz, for over-voltage protection of A.C. motor. Thetelay has the defferential mechanism and temperature compensation
and can plug ir HC1 series A.C, contactor.
