Rated 277 V AC phase-to-neutral (480Y/277 V wye systems), it breaks fault currents up to 6 kA — enough for most downstream distribution panels, though verify against your available fault current at the panelboard. Snaps onto standard DIN rail; the 2-pole form factor occupies two module widths in the enclosure, leaving room for adjacent breakers or auxiliaries.","metaTitle":"S202-D63 MCB 2P D 63A 277V AC, 6 kA Interrupt","metaDescription":"S202-D63 miniature circuit breaker, 2-pole, D-curve, 63 A, 277 V AC, 6 kA interrupting capacity.

This suits standard commercial and light industrial panelboards; for higher available fault currents (10 kA+), step up to the S200 series high-capacity variants."},{"question":"Will S202-D63 drop into a panel specified for S202M-C63 without rewiring?","answer":"Physically yes — same DIN-rail footprint, same 2-pole width, same terminal layout. The functional difference is the trip curve: D-curve tolerates higher inrush than the C-curve in S202M-C63, so swapping may affect selectivity coordination downstream."},{"question":"Where can I buy S202-D63?","answer":"Sourced and quoted to order against an RFQ through independent industrial-automation distribution.
