Product details

The breaker meets EN/IEC 60947-2 and is suitable for isolation per that standard.

Fit and mounting

Mounts to a backplate in either horizontal or vertical orientation, flat on the back. The 108 mm width occupies 12 module pitches at 9 mm each. Front connections top and bottom use Everlink lugs accepting 2.5–95 mm² rigid or stranded aluminium/copper, or 2.5–70 mm² flexible copper. Neutral is on the left. IP40 front face and IK07 impact resistance suit panel-mount applications where occasional tool contact is expected.
