Arc Fault Detection A-Type RCBO – WFD106B-030 (6A, B Curve, 30mA) Isolator Type A protection – detectsThe WFD106B 030 is a 6A, B Curve Arc Fault Detection (AFDD) RCBO, combining arc fault detection, residual current protection (30mA), short circuit, and overload protection into a single compact module. Built to BS 7671: 2018 (18th Edition) standards, it delivers the highest level of fire prevention for modern installations. Unlike a standard RCBO, this device features a microprocessor controlled Arc Fault Detection Device (AFDD). It continuously
