Tripping and tripping time
If the earth fault current is above the adjusted threshold the control device (e.g. UMC100.3 or
PLC) is responsible to switch off the motor within the specified tripping time (e.g. 1 s).
Earth fault detection time of CEM11-FBP.xxx is about 25 ms. UMC100.3 or PLC should use an
additional delay time to ignore short disturbances.
