Product details

Rated 415 V AC, it delivers a 7.5 kA breaking capacity per EN 60898, meaning it can safely interrupt a fault current up to 7.5 kA without welding the contacts or cascading damage upstream. The C curve (trips at 5–10× rated current) handles moderate inrush from motor-driven loads like pumps, fans, and compressors — a common spec for mixed-load subpanels in infrastructure buildings.

Width is 72 mm (4 modular units), depth 76 mm, height 90 mm.
