MOTOR / PUMP PROTECTION RELAYS

Transcription

1 MOTO / PUMP POTETI ELAS These relays are useful for protection of 3-phase A induction motors against various hazards. With their unique advantages they eliminate use of a thermal/bimetal relay for motor protection. eing 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 ompressor motor protection, as also for motors in machines, conveyors, cranes/hoists and lifts, and for pumps.
