That 63 A rating is the continuous current it carries without tripping under normal conditions — sized for a branch circuit or subfeed where the load current sits around 50-55 A sustained. The C-curve means the magnetic trip fires at 5-10x rated current (315-630 A), so it tolerates moderate inrush from small motors, transformers, or capacitor banks without nuisance trips, but clears fast on a hard short. The 6 kA interrupting rating at 277 VAC tells you the maximum fault current it can safely break — adequate for most downstream panelboards fed by a transformer, but verify the available fault current at the point of installation stays under that limit. ## Where it goes in the panel Snaps onto standard DIN rail — no tools needed for mounting, just clip it in and wire the line and load terminals. The single-pole format occupies one module width (roughly 17.5 mm), so it fits tight in a crowded enclosure. Rated 277 VAC line-to-neutral, which covers 120/208 V and 277/480 V wye systems on the phase-to-neutral leg. Common deployment: protecting a 3-phase motor branch circuit where only one phase needs overcurrent protection (ungrounded delta systems require multi-pole breakers; this is for grounded wye panels).","metaTitle":"ABB S201-C63 MCB 1P C 63A 277VAC, 6kA","metaDescription":"ABB S201-C63 1-pole miniature circuit breaker, 63A C-curve, 277VAC, 6kA interrupting capacity.
