It's a UL 1077 listed supplemental protector — meaning it's intended for branch-circuit backup or equipment-level protection, not as a main service disconnect. Compared to the 2-pole S202M-C10, the S201-K10 is a single-pole device with a K-curve instead of C-curve. The S202M-C10 offers 125 VDC interrupting and a second pole for 2-wire DC or split-phase AC circuits, but the K-curve on the S201-K10 gives it a tighter magnetic trip band — better for protecting loads with moderate inrush without oversizing. If your panel calls for a 1-pole K-curve at 10 A, the S202M-C10 won't drop in without rewiring; it's a different pole count and trip curve. The 1-pole footprint takes one module width (approx. 17.5 mm) — useful for tight panel layouts where every slot counts. Wire termination accepts copper conductors up to 25 mm² (solid or stranded). Torque terminal screws to 2.5 Nm. No auxiliary contact slot on this base unit; add an S2C-A1 accessory if remote status signaling is needed.","metaTitle":"S201-K10 ABB S200 Series 10A 1-Pole K-Curve Miniature Circui","metaDescription":"ABB S201-K10 supplemental protector, 10A, 277VAC, 6kAIC, K-curve, UL 1077.
