Trip Curve C means it tolerates moderate inrush currents (5–10× rated) before tripping, so it works on circuits with small motors, contactor coils, or capacitive loads that pull a brief startup surge without nuisance opening. ## Voltage and interrupting ratings — what they mean on site Rated 277 VAC, this MCB handles single-phase line-to-neutral circuits common in North American lighting panels or 277 V control loops. The 125 VDC rating covers DC control circuits or battery-backed supplies. The higher DC rating is a bonus for industrial DC bus protection. Two-pole width (roughly 36 mm) leaves room for adjacent breakers or accessories in the same row. No special busbar or comb needed for common feed — standard pin-type busbars fit the S200 family.","metaTitle":"ABB S202M-C2 Miniature Circuit Breaker, 2A, Curve C, 2-Pole","metaDescription":"ABB S202M-C2 miniature circuit breaker, 2 A, Trip Curve C, 2-pole, DIN rail mount. 277 VAC / 125 VDC, 6 kA interrupt AC.

The only difference is the current rating (2 A vs 20 A), so the S202M-C2 is a drop-in replacement if the branch load is under 2 A."},{"question":"Where can I buy S202M-C2 and how is it quoted?","answer":"S202M-C2 is sourced to order against an RFQ through independent distribution.
