Why Choose the ABB CEM11-FBP.020 Earth Leakage Monitor?
The ABB CEM11-FBP.020 is a dedicated earth leakage monitor with a 20 mm through-hole designed for use with the ABB UMC100.3 Universal Motor Controller. Supplied under ABB order code 1SAJ929200R0020, it forms part of the ABB 311531-FieldBusPlug product group and provides residual-current monitoring for industrial motor feeders.
The CEM11-FBP.020 monitors the sum of the currents passing through its measuring aperture. Under normal operating conditions the vector sum is approximately zero; when leakage or earth-fault current exceeds the selected threshold, the monitor changes its binary output signal. This enables the connected UMC100.3 to detect conditions such as insulation deterioration, leakage current and ground faults.
With eight selectable earth leakage thresholds from 80 mA to 1.7 A, the CEM11-FBP.020 can be adapted to different motor feeder requirements. Threshold selection is made directly on the unit, while an integrated test position simplifies wiring checks during commissioning and maintenance. The monitor operates from 24 V DC and is supplied with adapters for DIN-rail or wall mounting.

Earth Leakage Monitoring for Motor Feeders
The CEM11-FBP.020 operates by monitoring the combined current flowing through the conductors routed through its 20 mm aperture. When the currents are balanced, their sum is effectively zero. Leakage to earth creates a residual current, and when this exceeds the selected threshold the monitor changes its output signal so the UMC100.3 can respond according to the configured motor protection strategy.
This approach provides an effective way to detect earth faults and insulation-related leakage currents in industrial motor feeders. Eight selectable thresholds allow the monitoring sensitivity to be adapted to the installation, while the built-in test position provides a convenient means of checking the wiring and signal path during commissioning or maintenance.
