Rated 277 VAC and 500 VDC, this breaker covers single-phase line-to-neutral applications on 277/480 V wye systems and DC control bus protection. On the DC side, the 10 kA interrupting rating at 500 VDC handles tougher DC arcs, which don't self-extinguish at zero-crossing the way AC arcs do.","metaTitle":"ABB S202MUC-B32 MCB, 2P B 32A, DIN Rail","metaDescription":"ABB S202MUC-B32 miniature circuit breaker, 2-pole, Trip Curve B, 32 A, 277 VAC / 500 VDC, 6 kA interrupting capacity.
