Motor Protection Relay REM 6101MRS 755121
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.

Ordering informa-tion
When ordering REM 610 protection relays and/or accessories, please specify the follow-ing:
Order number HMI language set number Quantity
The order number identifies the protection relay type and hardware as described in Fig. 4 and is labelled on the marking strip under the lower handle of the relay. Use the order-ing key below to generate the order number when ordering complete protection relays.
Fig. 5 Ordering key
Use the ordering key in fig. 3 to generate the order number when ordering spare units.
Fig. 6 Ordering key for spare units
HMI language set numbers, corresponding terminology and languages included, are described in table 15 below:.
Note: The spare unit is a plain plug-in unit without enclosure, terminal connections and the optional communication module.
Note: To order a spare unit, select twice when generating the order number.
