It provides overcurrent and short-circuit protection for branch circuits in residential and infrastructure installations, with a breaking capacity of 3 kA at 230/400 V AC per IEC 60947-2. The C-curve (5–10× In) is the standard choice for inductive and motor-starting loads where inrush is moderate — it holds through the startup transient without nuisance tripping, unlike a B-curve on the same 80 A frame.
Occupies 1 MW (18 mm width) on a standard DIN rail, with a depth of 76 mm and an installation depth of 70 mm. The single-pole design means it protects one phase only — for a 3-phase supply you need three units or a 3-pole variant. Mounting position is unrestricted, and the IP20 rating (with conductors connected) is typical for enclosed panel use; no washdown protection, so keep it inside the cabinet.
