Curve D trips between 10× and 20× rated current, so a 2 A breaker holds through a 20–40 A surge for a few cycles. The 6 kA interrupting rating at 277 VAC covers most commercial panel fault-current levels; the 10 kA DC rating handles battery-backed or rectifier-fed circuits. Both poles switch together, so it's a single-pole-switched pair — not a two-pole common-trip for 240 V split-phase, but fine for 277 V line-to-neutral or 125 VDC. No rewiring or panel rework needed if you're swapping out an older S200 series or a competitor's 2-pole MCB on 35 mm DIN. Strip length 8 mm. Pitch matches standard 35 mm DIN-rail terminal blocks; the toggle handle clears adjacent breakers in a multi-row panel.","metaTitle":"ABB S202M-D2 S200M MCB 2A Trip Curve D 2-Pole DIN Rail","metaDescription":"ABB S202M-D2 S200M miniature circuit breaker, 2 A, Trip Curve D, 2-pole, DIN rail mount. 6 kA interrupting at 277 VAC, 10 kA at 125 VDC.
