The ADB420U is a single-module, single-pole RCBO with a 20A rated current, B-curve characteristic, and 10 kA breaking capacity. It includes 30mA Type A residual current protection suitable for detecting AC and pulsating DC fault currents. This unit replaces the discontinued ADA120U model.
The 20A B-curve rating is commonly used on socket outlet circuits or circuits supplying domestic appliances up to 20A. The single-module compact design provides space savings in distribution boards and consumer units.
The ADB420U operates at 230/240V AC and is designed for Hager Type B distribution board installations. It is IP20 rated, RoHS compliant, and DIN rail mountable.
