The DOMF01204 is a Domae miniature circuit breaker from Schneider Electric — a 2-pole, C-curve unit rated 4 A at 230 V AC with a 6000 A breaking capacity (Icn) per IEC 60898-1. At 36 mm wide on a DIN rail, it fits a standard 4-module pitch (9 mm per pitch) — common for a 2P MCB in a domestic or light commercial distribution board.
Clip-on mounting to a DIN rail, with tunnel-type terminals accepting 1–25 mm² rigid or 1–16 mm² flexible cable. The 18 mm phase-to-phase connection pitch lines up with standard Domae busbars. IP20 on the body, IP40 inside a modular enclosure — fine for dry indoor panels, not for washdown areas.
Environmental & Durability
Rated for 10,000 electrical cycles and 20,000 mechanical cycles. Operating temperature range is -5 to 60 °C, storage from -40 to 85 °C. Tropicalisation class 2 per IEC 60068-1 handles 95% relative humidity at 55 °C — suitable for coastal or high-humidity sites without conformal coating.
