Product details

Breaking capacity is 6 kA per EN 60898 and 15 kA per IEC 60947-2, so it handles fault currents up to 15 kA in industrial panels where the upstream transformer can deliver that level. DC rating maxes at 72 V, covering 48 V and 60 V control buses.

Width is 36 mm — two modular units on a DIN rail. Mounts in any position. The quick-assembly system clips onto the rail without tools. IP20 with connected conductors; not for wet locations without an enclosure.

Ambient range -40 °C to 75 °C, with humidity limits: 95% up to 55 °C, derating to 35% at 75 °C. Halogen-free and silicon-free construction. Touch protection integrated.

Neutral conductor switching is not provided — this is a 2-pole breaker switching both phase conductors, not a 1P+N arrangement. Suitable for mechanical engineering and industry environments per the manufacturer designation. Sealing option available for tamper-proof installations.
