Single Phase Protection Relay

Relay MPR300 is a three-phase LT motor protection relay for motor sizes up to 50KW (max.
88 A current). It is a low cost solution, offering five major protections for motors widely used
in fans, pumps, crushers, mills, compressors, belt conveyors, centrifuges, mixers, ventilators,
escalators, motorized valves etc. Major advantage is that it provides EF co-ordination in
contactor-started motors, thus offering greater security, operator safety and economy. The
relay is micro controller based, highly user friendly and compact with inbuilt CTs. The relay
can also be used for protection of larger motors by using external CTs. medium voltage and
high voltage sub-stations.
