In the contactor controlled motor driveapplication, the protection also covers the feeder cable and the cable box. The CBcontrolled application features a transformer and motor drive application. The loadside 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 aresupervised through direct temperature measurement via embedded sensors.Motor Protection 1MRS756304 CREM610Product version: C Issued: 30.10.20096 ABB
