Motor Protection Relay REM 610

Application 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-
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.
Design 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.
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.
