Product description
Setting the earth fault current
The current threshold when the CEM11 signals an earth fault can be adjusted with a rotary switch.
The test position can be used to test the CEM11 and connected devices like the UMC100.3. This allows simple
verification if the earth fault related settings in the UMC100.3 are all done correctly and e.g. lead to a trip.
