It mounts on a standard DIN rail and is rated for 230 VAC with a 15 kA interrupting capacity — the AC fault-clearing figure that governs its use in distribution panels where high inrush loads like motor starters or transformers are present. The DC interrupting rating is 10 kA. ## What the ratings mean for fit Trip Curve D means the magnetic trip threshold is set to 10–20× In (160–320 A instantaneous), which avoids nuisance tripping on high inrush currents from motor starting, transformer energization, or capacitive loads. This makes the S803C-D16 a fit for motor branch circuits and industrial equipment with inductive kick, not for general lighting or resistive loads where a B or C curve would be more appropriate. The 15 kA interrupting capacity at 230 VAC means it can safely clear a bolted fault up to that level without welding contacts or cascading failure upstream — a key number for the panel designer verifying SCCR coordination.","metaTitle":"ABB S803C-D16 MCB, 3P D-Curve, 16 A, 15 kA","metaDescription":"ABB S803C-D16 miniature circuit breaker, 3-pole, Trip Curve D, 16 A, 230 VAC, 15 kA interrupting capacity.
