Product details

Backplate-mounted, front-connected, with Everlink lug terminals accepting 2.5 to 95 mm² rigid or stranded aluminium/copper conductors.

IP40 enclosure protection (IK07 impact resistance) — suitable for installation in a dry indoor panel where tools are required to access live parts. The grey RAL 7016 colour is the standard Schneider finish for this range.

Rated for 20,000 mechanical cycles and 20,000 electrical cycles at 440 V In (10,000 cycles at 440 V In/2, 5,000 cycles at 690 V In). Category A utilisation (not intended for frequent switching of motor loads — this is a distribution breaker, not a motor-circuit protector). Power dissipation per pole is 3.8 W, relevant for thermal management in a sealed enclosure.

Mounts on a backplate in horizontal or vertical orientation. 9-module pitch (9 x 9 mm = 81 mm wide). Front connection top and bottom. Everlink lug terminals accept 2.5 to 95 mm² rigid or stranded aluminium/copper (2.5 to 70 mm² flexible copper). Connection pitch is 35 mm with spreaders, 27 mm without. The flag indicator (green) shows presence of auxiliary contacts. Relative humidity 0 to 95%.
