It clips onto a standard DIN rail, so it drops into any distribution or control panel that already has the rail profile — no adapter plate, no drilling. Curve D means the magnetic trip point is set between 10x and 20x In (320 A to 640 A).
Interrupting capacity and voltage ratings
Rated to interrupt 15 kA at 230 VAC and 10 kA at 250 VDC. The 230 VAC rating covers single-phase line-to-neutral circuits in most industrial control panels. The 250 VDC rating is useful for DC bus protection in drives or battery-backed control circuits — something not every DIN-rail MCB offers.
