Hager ADB920R 20A 6kA 30mA 1P+N B Curve Type A Bi-Directional RCBO For Residential Installations

Hager ADB920R Description

The Hager ADB920R 20A 6kA 30mA 1P+N B Curve Type A Bi-Directional RCBO provides advanced protection for residential electrical circuits by combining the functions of an MCB and RCD within one compact device. Designed to meet the requirements of modern consumer units, it protects against overloads, short circuits and earth leakage faults while helping installers achieve compliance with the latest BS 7671 Wiring Regulations.

Part of Hager's innovative ADB bi-directional RCBO range, the ADB920R features a 20A current rating and B Curve tripping characteristic, making it ideal for general-purpose domestic circuits including radial power circuits, dedicated appliance supplies and other applications where moderate inrush currents are expected. The integrated 30mA Type A residual current protection detects both AC and pulsating DC fault currents, providing enhanced protection for modern electrical installations containing electronic equipment, smart devices and energy-efficient appliances.

Its bi-directional capability allows power to be supplied from either the top or bottom terminals, offering greater installation flexibility and making it particularly suitable for renewable energy systems, battery storage applications and micro-generation installations. The compact single-module 1P+N design helps maximise available space within consumer units, while the switched neutral pole improves safety during maintenance, testing and fault isolation.

Manufactured to Hager's renowned quality standards, the ADB920R delivers reliable long-term performance, straightforward installation and comprehensive circuit protection for today's residential electrical systems.
