Eaton Residual Current Circuit Breakers (RCDs) - FRCdM Series Types B, B+ and Bfq

The FRCdM series of residual current devices from Eaton form part of the xEffect range providing the highest RCD protection for both people and appliances. These devices allow for permanent indication of actual electrical leakage with built in digital features.These types B, B+ and Bfq RCCBs detect AC pulsating, DC residual and smooth DC residual currents.

Type B RCCBs are the standard type and are sensitive to all residual current flows up to 1 kHZ. Type B+ devices are sensitive to all residual currents while also being equipped with a special tripping curve that limits the trip current to max. 420 mA for frequencies up to 20 kHz (Type B+ also meets superior fire protection regulations according to VDE 0664-400). Type Bfq devices meanwhile can tolerate system-induced earth leakage currents at higher frequencies up to 50 kHz.
