The Hager ADB450U is a compact Residual‑Current Breaker with Overcurrent protection (RCBO) that combines the functionality of an RCD and an MCB in a single module to protect electrical circuits from overloads, short circuits, and earth leakage faults. This variant is rated at 50 A, features 30 mA Type A residual current detection, a B‑curve tripping characteristic suitable for general power and lighting circuits, and a 10 kA short‑circuit breaking capacity for robust protection against high fault currents. Designed for DIN rail mounting in a single‑module (1M) format, it offers space‑efficient installation within consumer units and distribution boards. The ADB450U is suitable for domestic, commercial, and light industrial applications where combined overcurrent and leakage protection is required.
The Hager ADB450U is suited for circuits that require higher current protection along with combined overcurrent and earth leakage detection. Typical applications include larger power circuits, commercial premises distribution boards, machinery feeds, and higher capacity lighting or outlet circuits in domestic and industrial installations.
The ADB450U delivers a robust and compact solution for protecting circuits against both overcurrent and residual leakage faults in a single modular device. Its Type A residual current sensitivity offers detection for both AC and pulsating DC leakage, while the B‑curve trip profile balances protection against nuisance tripping for everyday loads. The 50 A rating and 10 kA breaking capacity support higher load demands, and the single‑module DIN rail format simplifies installation and saves space within electrical distribution boards.
