4. Application

Figure 2. REM610 can be used for the protection of both circuit-breaker controlled and

contactor controlled motor drives. In the contactor controlled motor drive

application, the protection also covers the feeder cable and the cable box. The CB

controlled application features a transformer and motor drive application. The load

side of the transformer is earthed via a resistor, which enables current measuring earth-

fault protection to be used. In both applications, the critical motor temperatures are

supervised through direct temperature measurement via embedded sensors.
