The 15 kA interrupting capacity at 230 VAC means it can safely clear a fault up to that level without welding its contacts or cascading failure upstream — critical for maintaining selectivity in a distribution board. On the DC side, it interrupts up to 10 kA, so it handles battery-backed control circuits or DC link protection in the same panel footprint. ## Deployment context Snaps onto standard DIN rail in any 3-phase panel — motor control centers, sub-distribution boards, or machine supply disconnects. The C-curve (5–10x In magnetic trip) suits moderate inrush loads like small motors, transformers, or lighting banks where a B-curve would nuisance-trip but a D-curve delays too long.","metaTitle":"ABB S803C-C16 MCB, 3P, C-Curve, 16 A, 15 kA","metaDescription":"ABB S803C-C16 S800C MCB, 3-pole, C-curve, 16 A, 15 kA interrupting at 230 VAC.
