This 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 currents up to 6 mA.
The digital RCCB from the xEffect series do more than just switch off. They monitor electrical installations and give advance warning of critical current flows. So plant / factory shutdowns – and the resulting costs – can be avoided.
Fault current 30-50 %
Check the connected devices.
The yellow LED shows a residual current in the ambit of 30 to 50 % of the nominal fault current. Before the system is shut down, professional countermeasures can be taken.
Fault current > 50 %
Contact an electrican.
When the red LED lights up, the leakage current is already higher than 50 % of the nominal fault current. Therefore the system is in a critical status – the digital RCCB only trips when the fault current continues to increase.
