This FRCdM Type A, U, R residual current circuit breaker is part of the xEffect series for industrial/commercial applications. The FRCdM meets the highest requirements for the protection of both people and equipment. The FRCdM Type A is designed for systems with alternating and pulsating direct currents.
Type A RCCBs will also operate correctly in the presence of smooth direct residual current up to 6 mA.
The digital RCCBs from the xEffect series can do more than just switch off. They monitor electrical installations and give advance warning of critical current flows. So that system shutdowns – and the associated costs – can be avoided.
Fault current 30% to 50 %
Check the connected devices.
The yellow LED indicates residual currents in the range of 30 % to 50 % of the nominal fault current.
This makes it possible to take appropriate counter measures before the system shuts down.
Fault current > 50 %
Contact an electrician.
If the red LED lights up, the leakage current exceeds 50 % of the nominal fault current. This means that the system is in critical condition – the digital RCCB will only trip if the fault current continues to increase.
