Motor Protection Relay

REM 610 is a versatile multifunction protec-

tion relay mainly designed for protection of

standard medium and large MV asynchro-

nous motors in a wide range of motor appli-

cations. It handles fault conditions during

motor start up, normal run, idling, and cool-

ing down at standstill, e.g. in pump, fan, mill

or crusher applications.

The large number of integrated protection

functions makes REM 610 a complete protec-

REM 610 is based on a microprocessor envi-

ronment. A self-supervision system continu-

ously monitors the operation of the relay.

The HMI includes a Liquid Crystal Display

(LCD) which makes the local use of the relay

safe and easy.

tion against motor damage. The relay can be

used with both circuit-breaker controlled and

contactor controlled drives.

REM 610 can equally well be used to protect,

for instance, feeder cables and power trans-

formers which require thermal overload pro-

tection and, for instance, single-, two- or

three-phase overcurrent or non-directional

earth-fault protection.

Local control of the relay via serial communi-

cation can be carried out with a computer

connected to the front communication port.

Remote control can be carried out via the rear

connector connected to the control and moni-

toring system through the serial communica-

tion bus.
