Trip Curve K is the key: it trips magnetically at 8 to 12 times rated current, so it rides through motor inrush (typically 6-8x FLA) but clears a hard short fast. In a 230/400 V panel with a transformer kVA rating that keeps the prospective short-circuit current under 15 kA, this breaker coordinates cleanly — no need for a current-limiting fuse upstream. The DC rating at 10 kA covers battery-bank or DC-bus protection in the same enclosure, which saves a separate DC-rated fuse holder. DIN-rail snap-on mounting (per) means it clips onto a standard 35 mm rail in the distribution board or motor control center. Three-pole width at 80 A takes three modular units (17.5 mm each) — 52.5 mm of rail space. That keeps the panel fill factor tight: you can stack a 3-pole 80 A K-curve next to a 3-pole 32 A C-curve for the lighting subfeed without a busbar adapter. Lifecycle stage is current, meaning ABB still manufactures this exact order code. No EOL notice, no last-time-buy window to watch.","metaTitle":"S803C-K80 MCB 3P K 80A, 15kA Interrupt Rating","metaDescription":"S803C-K80 3-pole MCB, Trip Curve K, 80 A, 15 kA interrupting at 230 VAC, 10 kA DC.
