Rated 10 kA per EN 60898 and 35 kA per IEC 60947-2 at 400 V AC, it's got the interrupting capacity for industrial panels where fault currents run high. It's a 1 MW unit (18 mm wide), so it takes up one slot on the DIN rail. The quick-assembly system means it snaps on and off without tools, which saves time when you're populating a panel or swapping a failed breaker out here in the grease.
The D tripping characteristic is the headline here. The thermal trip handles sustained overloads, while the magnetic trip reacts to short circuits. On a D-curve, the magnetic trip is set to activate at 10 to 20 times the rated current, so it won't drop out on a motor starting surge but will clear a hard fault fast. Rated for 400 V AC (single-phase) and 440 V AC multi-phase, plus 60 V DC (72 V DC max). The DC rating is useful for control circuits or battery-backed loads, though it's primarily an AC breaker. The operating frequency is 50/60 Hz, standard for global installations. The surrounding humidity limits are 95% up to 55 °C, then derated above that. IP20 protection with conductors connected — that's standard for a DIN-rail MCB in an enclosed panel. It's not for washdown areas; keep it behind a gland plate or cabinet door. Sealable per the spec, so you can lock it out for LOTO procedures.
One modular width (18 mm) on a standard DIN rail. Mounting position any orientation — vertical, horizontal, upside down, doesn't matter. The quick-assembly system lets you snap it onto the rail and remove it with a screwdriver lever, no prying or rail damage.
