    REM 610 Motor protection Relay 1MRS 752263-MUM Technical Reference Manual Safety information Dangerous voltages can occur on the connectors, even though the auxiliary voltage has been disconnected. National and local electrical safety regulations must always be followed. The device contains components which are sensitive to electrostatic discharge.

  • Page 10: Instructions

    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 transformers which require thermal overload protection and, for instance, single-, two- or three-phase overcurrent or non-directional earth-fault protection.
