        The Hager ALM420T is a 3P+N RCBO that provides combined overcurrent and earth leakage protection in a space-saving 3-module design. Rated at 20A, Type A, and 30mA with a C-curve tripping characteristic, it’s built for 400-415V AC three-phase systems commonly used in commercial and light-industrial environments.

        This RCBO features a 6 kA short-circuit breaking capacity and is DIN-rail mountable for quick, easy installation. Pre-fitted tails reduce installation time and accommodate 1-25 mm² conductors. With IP20 protection and a 4kV impulse withstand rating, the ALM420T ensures long-term safety and compliance with IEC/AS standards.
