The ABB S803C-K16 is a 3-pole miniature circuit breaker from the S800C series, rated 16 A with a Trip Curve K characteristic. It mounts on a standard DIN rail and is rated for 230 VAC with a 15 kA interrupting capacity, plus 10 kA on DC circuits.
The 3-pole format covers three-phase circuits; the K curve handles motor starting currents and transformer inrush without nuisance tripping, while still providing short-circuit protection at 15 kA (AC) or 10 kA (DC).
Sourced and quoted to order against an RFQ through our independent distribution network. Availability and current pricing are confirmed at quote time.
Rated 16 A with a Trip Curve K characteristic — magnetic trip at 8 to 12 times rated current, suited for motor and inductive loads.
Both are 3-pole DIN-rail MCBs from the same S800 family, so the physical footprint and mounting are identical. The key difference is the trip curve — K vs D — and the interrupting rating (15 kA vs 50 kA). For a panel originally designed around a D-curve, verify the required coordination and short-circuit rating before substituting.
Alternative models and sibling configurations in the same ABB series. For obsolete or discontinued parts, these models can serve as compatible replacements or functional alternatives for plant maintenance.
