These relays are useful for protection of 3-phase AC induction motors against various hazards. With their unique advantages they eliminate use of a thermalbimetal relay for motor protection. Being current sensing, they are to be selected according to motor rating and are available for practically all ranges of motors. These relays are ideally suitable for Air-conditioning Compressor motor protection, as also for motors in machines, conveyors, craneshoists and lifts, and for pumps.
