The 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 18th Edition Wiring Regulations (Amendment 2) is essential.

Installer Tip: Use the B Curve for standard circuits with low inrush current such as domestic lighting or socket outlets. For EV chargers, motors, or heat pumps, select the C Curve version.
