Electronic Motor Protection Relays

The new standard of next-generation motor protection relays! LS ELECTRIC electronic motor protection relay (EMPR) supersedes thermal overload relays, also known as electronic overcurrent relays, to safeguard low voltage motors. Because of its accuracy and real-time data processing, EMPR is extremely dependable. LEDs on EMPRs indicate system status, and features phase loss, phase reverse, unbalanced, stall, lock, ground fault and short circuit protection (depending on the model). fuu that display load current, save cause of failure, and provide communication features. EMPR are EMC tested and approved to operate safely without any malfunction caused by electromagnetic wave and surge.
