The 63 A rating governs the continuous load it can carry without tripping; the C-curve (5–10× In magnetic trip) suits it for mixed resistive and moderate inductive loads where inrush is not severe — typical for general-purpose branch circuits in commercial and light industrial installations. Its interrupting rating of 10 kA at 277 V AC per the evidence means it can safely clear a fault up to that prospective short-circuit current without rupturing, which is the standard requirement for most secondary distribution panels in North American 480Y/277 V systems. For BOM freeze and compliance documentation, the manufacturer provides RoHS and REACH declarations as standard for the System pro M compact series. The part carries CE marking for the European market; UL/CSA listing should be confirmed against the specific nameplate variant if required for North American installations. ## Panel integration The 4-pole width occupies four modular spaces (72 mm at 18 mm per pole). Verify busbar compatibility for 63 A feed-through; the S200 series accepts plug-in feeders and auxiliary contacts without additional wiring.","metaTitle":"ABB S204-C63 MCB, 4P C 63A, 10 kA, DIN Rail","metaDescription":"ABB S204-C63 MCB, 4-pole, Trip Curve C, 63 A, 277 V AC, 10 kA interrupting rating.

The only difference is the 63 A rating versus 32 A, so the panel busbar and feeder must be sized for 63 A continuous load."},{"question":"Who supplies S204-C63 and how is it quoted for volume purchases?","answer":"The S204-C63 is sourced to order against an RFQ through independent distribution.
