PDC-Eaton Moeller series xEffect - FRCdM Type B, B+, Bfq RCCB
Type B+ 's tripping curve limits the tripping current to max. 420mA for frequencies up to 20kHz acc. to VDE 066-440. Type Bfq's tripping curve (non-sensitive against system caused earth leakage currents) complies with the specifications of Type B avoiding unwanted tripping in applications with high-power frequency converter controls and is adapted for all residual current types up to 50kHz. FRCdM belongs to xEffect industrial/commercial series. Type B's sensitivity increases safety and reliability by reducing nuisance tripping. Direct residual currents can occur in applications with frequency inverters, photovoltaic systems and devices with power semiconductors. These RCCB's fulfills highest requirements for protecting people and equipment. Type B, B+ & Bfq detect AC, pulsating DC and smooth DC residual currents. Smooth DC residual currents can occur in applications with photovoltaic systems, frequency converters or electronic components. All have integrated digital technology permanently showing actual leakage current.
