Hager 20A Bi-Directional RCBO Type A 30mA 6kA Single Pole & Switched Neutral, B Curve

The Hager ADB920R is a 20A bi-directional RCBO with a B curve trip characteristic, designed to provide combined overload, short circuit and earth leakage protection in a single compact device. Featuring a single pole and switched neutral configuration, Type A sensitivity and a 30mA tripping current, it delivers reliable circuit protection for modern electrical installations where current flow in both directions is required.

Built within a compact 1 module format, the ADB920R helps maximise available space within the consumer unit while delivering dependable overcurrent and residual current protection. Its Type A sensitivity provides protection against both AC and pulsating DC residual fault currents, making it particularly suitable for modern installations containing electronic equipment and appliances.

The B curve characteristic makes this RCBO well suited to residential and light commercial circuits, providing rapid disconnection under fault conditions while protecting lighting circuits, socket outlets and other general-purpose final circuits.

Manufactured to comply with BS EN 61009-1 and supporting the requirements of BS 7671:2018 Amendment 2, the ADB920R combines high levels of protection with straightforward installation. The device features a 500mm flying neutral lead and is designed for applications where bi-directional current flow is required, including modern energy systems and micro-generation installations.
