The WER16C-030 is a 16A C Curve High Immunity Type A RCBO built for EV chargers, motors, heat pumps, and inverter-fed systems. It provides overload, short-circuit, and 30mA residual current protection, while the high immunity design prevents nuisance tripping in circuits subject to harmonics and transient voltages.

With double pole disconnection and bi-directional wiring, this RCBO is fully compliant with the 18th Edition Wiring Regulations (Amendment 2), making it suitable for both new installs and retrofits in solar, EV, and renewable energy applications.

Installer Tip: Choose the C Curve when fitting EV charge points, motors, or heat pumps with high inrush currents. For low inrush domestic lighting or socket circuits, select the B Curve variant instead.
