Product details

The 3-pole (3P) configuration protects three phases of a distribution circuit. Its breaking capacity is 25 kA Icu at 380/415 V AC 50/60 Hz per IEC 60947-2, which means it can safely interrupt a fault current up to 25 kA at that voltage without damage to itself or downstream equipment. For a 220/240 V supply, the Icu rises to 40 kA.

Mounts on a backplate in horizontal or vertical orientation. Front connections on both upside and downside simplify panel wiring. The 35 mm connection pitch matches standard busbar systems. IP40 enclosure protection and IK07 impact resistance suit it for enclosed distribution boards.

Suitable for isolation per that standard.
