The Schneider Electric A9D73625 is an Acti9 ISPN Vigi residual current breaker with overcurrent protection (RCBO) — a single-module (18 mm wide, 2 x 9 mm pitches) device combining a 25 A thermal-magnetic MCB with integrated 30 mA earth-leakage protection in a 1P+N format.
The 18 mm width (2 modules) and 70 mm depth leave clearance for standard distribution board covers and gland plates. Tunnel-type terminals accept 1...16 mm² rigid or flexible upstream, 1...10 mm² downstream; strip lengths are 13 mm upstream and 11 mm downstream.
