The Schneider Electric A9T26620 is an Acti9 iDPN N VigiARC RCBO combining a 20 A thermal-magnetic MCB (Curve C) with integrated earth-leakage protection in a 1P+N module.
The 36 mm width (4 x 9 mm pitches) matches the Acti9 modular footprint — one module wide. Neutral is on the left, line on the right. The toggle switch provides ON, OFF, and fault-trip local signalling.
