Overview

Brought to you by Lauritz Knudsen Electrical & Automation-India’s largest manufacturer of LT Switchgear, the eMPR series of Electronic Motor Protection Relays offer Current based Protections for Three Phase Low Voltage Motors.


eMPR is a compact Microcontroller based Motor Protection Relay with inbuilt CTs up to 88 Amp.

Benefits

Electronic Overload Relay [EOLR] combined with inbuilt Locked Rotor and Phase failure makes eMPR an ideal solution for Protection of Motors used in fans, pumps, crushers, mills, compressors, belt conveyors, centrifuges, mixers, ventilators, escalators etc.

Earth Fault protection in eMPR300, eMPR300D and eMPR300I ensures enhanced Motor and Operator safety along with coordination of Motor feeder with upstream breakers.
