The 15 kA interrupting rating at 230 VAC covers most industrial fault levels upstream of a distribution transformer; the 10 kA DC rating handles battery-backed DC bus protection. ## Integration note DIN-rail mounted, 3-pole form factor. The 63 A rating and C-curve make it a direct drop-in for a panel originally specified with the 2-pole S202M-C63 — same curve, same interrupting DC rating, just one more pole for three-phase loads. No rewiring of the busbar arrangement needed if the panel already carries a 3-pole breaker.","metaTitle":"ABB S803C-C63 3-Pole 63A C-Curve MCB, 15 kA","metaDescription":"ABB S803C-C63 3-pole 63A C-curve MCB, 15 kA interrupting at 230 VAC.

The S803C-C63 adds a third pole for three-phase loads, so it fits a panel originally laid out for the 2-pole S202M-C63 as long as the busbar and wiring support three poles."},{"question":"Where can I buy S803C-C63 and how is it quoted?","answer":"The S803C-C63 is sourced to order against an RFQ through independent distribution.
