Description

The ADC420U is a 1-module, single-pole RCBO with a 20A C-curve characteristic and 10 kA breaking capacity. It provides 30mA Type A residual current protection and replaces the ADA170U in the Hager product range. The compact design integrates MCB and RCD functions into a single unit.
At 20A with C-curve, this RCBO suits circuits powering equipment with high startup currents, such as compressors, small machinery, or larger domestic appliances. Combined protection simplifies panel design and reduces wiring.
The ADC420U operates at 230/240V AC and is designed for Hager Type B distribution boards. It is DIN rail mountable, IP20 rated, and RoHS compliant.
