High Immunity RCBO – 16A B Curve, Type A, 30mA (WER16B-030) WEC Main Switch & Surge C Curve tripping – tripsThe WER16B 030 is a 16A B Curve High Immunity Type A RCBO designed for solar PV, battery storage, and EV charger circuits. It provides combined overload, short circuit, and 30mA residual current protection, with added resilience against nuisance tripping from harmonics or transient voltages. With double pole disconnection and bi directional wiring, this RCBO is a reliable choice for inverter fed systems and domestic boards where compliance with the
