The C-curve means the magnetic trip operates at 5 to 10 times rated current, so it handles moderate inrush from small transformers or capacitor banks without nuisance tripping — a good fit for auxiliary DC supplies in rail cars. At 10 kA DC rated breaking capacity under IEC 60947-2, this breaker can safely interrupt fault currents up to that level on a 220 V DC bus. That is a solid rating for a 1-module-wide unit, and it avoids cascading failures upstream in the distribution panel.
The lifecycle stage is listed as current, meaning the manufacturer continues to produce this order code. It is sourced and quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time.
The breaker snaps onto a DIN rail via the quick-assembly system and occupies one modular width unit (18 mm,). Its IP20 rating with connected conductors is standard for enclosed panel installation — not for wet or dusty environments without an outer enclosure. Pollution degree 3 and overvoltage category III suit it for fixed industrial and railway power distribution.
