Hager ADB920R B20A Bidirectional RCBO
The Hager ADB920R B20A Bidirectional RCBO is a compact 20A B Curve 30mA Type A protective device designed for reliable overload, short circuit and residual current protection in residential and commercial electrical installations. Manufactured to BS EN 61009-1 standards, this 1 module 2P switched neutral RCBO offers a 6kA breaking capacity, Type A residual current protection and bidirectional functionality, making it ideal for modern installations including renewable energy and micro-generation systems. The updated design now includes a longer 500mm neutral lead compared to previous versions, providing improved flexibility and easier installation within consumer units. The device also supports insulation resistance testing at 500V DC without disconnecting conductors, helping reduce installation and maintenance time.
Designed specifically for use with Hager Consumer Units and distribution boards, the Hager ADB920R B20A Bidirectional RCBO delivers dependable circuit protection while maintaining full compatibility with Hager electrical systems. Its compact single module format helps maximise available space within modern consumer units, making it ideal for both new installations and upgrade projects.
