Description

The AD920J is a 2-pole, 20A RCBO with a B-type tripping curve, 6kA breaking capacity at 240V AC, and 30mA Type A residual current sensitivity. The 20A rating suits circuits supplying socket outlets, immersion heaters, or other moderate loads where B-type tripping provides adequate protection.
As a Type A device, the AD920J responds to both sinusoidal and pulsating DC residual fault currents. It occupies 2 DIN rail modules and accepts conductors from 1–16mm² (flexible) and 1–25mm² (rigid) at screw terminals.
Rated IP2X and RoHS compliant, the AD920J is suitable for residential and light commercial circuit protection, providing combined overcurrent and 30mA earth fault protection in a compact format.
