Earth fault monitors CEM11-FBP.xxx for use with the Universal Motor Controller UMC100.3
The CEM11-FBP.xxx device monitors if the sum of the currents flowing through it is zero
2CDC345011F0008 (factorial addition). If the sum is zero, no residual current is present. If the residual current is

above an adjusted threshold value, the output signal of the CEM11-FBP.xxx changes. It can be
used in motor feeders to detect leakage currents, as well as ground faults, caused for example
by insulation breakdowns.

CEM11-FBP.xxx
• CEM11-FBP.xxx is connected to a digital input of the UMC100.3
• Earth fault current threshold can be set in eight steps with a screwdriver
• Test position for easy control of the wiring

CEM11-FBP.xxx is delivered with adapters for DIN-rail or wall mounting.
CEM-11.FBP.120 is for wall-mounting only.
