Motor protection relay ABB Oy Distribution Automation

The motor protection relay REM 610 is part of the RE_ 610 series of numerical relays for the protection and supervision of utility substations, and industrial switchgear and equipment.

The motor protection relay REM 610 is primary targeted at protecting large asynchronous low-voltage motors and small and medium-sized high-voltage asynchronous motors. REM 610 handles electrical fault conditions during motor start up, normal operation, idling, and cooling down at standstill, e.g. in pump, fan, mill or crusher applications. The relay can be used with both circuit-breaker controlled and contactor-controlled drives. REM 610 can also be used for the protection of cables feeders and distribution transformers that require thermal overload protection besides overcurrent, earth-fault and phase unbalance protection.

The numerical motor protection relays support a wide range of standard communication protocols, among them the IEC 61850,
IEC 60870-5-103, Modbus, and Profibus.
