The Hager ADB425U is a combined Residual‑Current Breaker with Overcurrent protection (RCBO) designed to deliver reliable safety for circuits requiring both overcurrent interruption and earth leakage detection. Configured with a 25 A rated current, a 30 mA Type A residual current sensitivity suited to detecting AC and pulsating DC leakage, and a B‑curve tripping characteristic for general applications, this unit protects against overloads, short circuits, and leakage faults. It offers a 10 kA short‑circuit breaking capacity, ensuring a robust response to high fault currents. Its compact, single‑module DIN rail design makes it ideal for space‑efficient installations in consumer units and distribution boards across domestic, commercial, and light industrial settings.
The Hager ADB425U is designed to protect individual circuits in consumer units and distribution boards that require combined overload and earth-leakage protection. Applications include lighting circuits, power outlets, and dedicated appliance circuits. Its Type A residual current sensitivity ensures suitability for installations containing electronic and non‑linear loads.
The ADB425U delivers trustworthy protection with a balance of overcurrent, short-circuit, and residual-current safety in a single compact module. The B‑curve tripping provides a responsive yet resilient profile for general circuits, while Type A leakage detection covers modern waveform loads. With its DIN rail-mountable modular design and robust 10 kA capacity, it’s well-suited to professional electrical installations that demand space‑efficient, high‑performance protection.
