REM 610 is a multi-function motor protection relay designed for medium and large standard asynchronous motor protection and is widely used in a variety of medium voltage motor equipment. Faults can be handled during motor start-up, operation, idling and stop cooling, especially in pumps, blowers, grinders or crusher applications.
REM 610 features a range of integrated protection features to provide complete protection against motor failures. The relay can be used in motor systems controlled by circuit breakers and contactors.
In addition, REM 610 is suitable for protecting power cable outlets and power transformers requiring thermal overload protection. It also has single-phase, two-phase or three-phase overcurrent protection or directional grounding protection.

REM 610 is based on a multi-processor design environment. The perfect self-test system can continuously monitor the operation of the relay.
The human Machine Interface (HMI) provides a liquid crystal display (LCD) to operate the relay safely and quickly in situ.
Local control of relay can be realized through serial communication with computer through front panel communication port. Remote control can be realized through serial communication bus and control and monitoring system through backplane communication module.
