The DIN-rail footprint drops into standard distribution panels or sub-distribution boards without adapters. The closest functional peer is the S803S-D63, which shares the same 63 A rating, Trip Curve D, 3 poles, DIN-rail mounting, and 230 V AC voltage. Both are current-production parts; the choice comes down to the required SCCR for the installation point. Snap-on DIN-rail mounting for 35 mm rail per EN 60715. The 3-pole block occupies three modular units (17.5 mm per pole). Wire termination accepts copper conductors up to 35 mm²; torque settings for the terminal screws are specified on the side label. The S800N series uses a common busbar system for incoming feed — order the appropriate pin-and-sleeve busbar if paralleling multiple breakers in a group.","metaTitle":"ABB S803N-D63 MCB, 3P D 63 A, DIN Rail","metaDescription":"ABB S803N-D63 miniature circuit breaker, 3-pole, Trip Curve D, 63 A, 230 V AC, DIN rail mount.

Curve D provides a magnetic trip threshold of 10–20× In, designed for high-inrush loads like motors and transformers."},{"question":"Will S803N-D63 drop into a panel specified around S803S-D63 without rewiring?","answer":"Yes, the S803N-D63 and S803S-D63 share the same 3-pole DIN-rail footprint, 63 A rating, and Trip Curve D. The main difference is interrupting capacity — the S803S is rated 50 kA versus the S803N's standard rating. If the available fault current at the panel is within the S803N's capability, it is a direct mechanical and electrical swap."},{"question":"Where can I buy S803N-D63 and how is it quoted?","answer":"The S803N-D63 is sourced to order against an RFQ through independent distribution.
