JRS4-D Range Thermal Overload Contactor Relay JRS4-D Range Thermal Overload Contactor Relay

JRS4-D range thermal overload contactor relay is ideal for use in AC 50Hz or 60Hz electrical circuit with rated operating voltage up to 660V. It functions to protect AC motors against damages caused by overload and phase breaking. The bimetal type product is designed with setting current regulation device and ambient temperature compensator as well. It can be either manually reset or automatically reset. To suit customers' application demands, the contactor relay can work on eight-hour duty, continuous duty or periodical duty.
