On the DC side it's rated 10 kA at 125 VDC, which covers control power supplies and battery-backed circuits. ## Panel fit and DIN-rail integration Snaps onto standard DIN rail — same footprint as every other S200M 2-pole breaker. Two poles mean it switches both line conductors in a single-phase circuit or both legs in a DC system. The neutral is not switched unless you add a separate 1-pole unit — this breaker is for line-side protection only. ## Lifecycle and sourcing — still a current production part For a line-down replacement or a BOM freeze, the S202M-C4 is a straight drop-in for any S200M 2-pole slot. If you need a higher amp rating, the S202M-C10, S202M-C16, or S202M-C20 share the same physical footprint and interrupting ratings.","metaTitle":"ABB S202M-C4 S200M MCB, 4 A, Curve C, 2-Pole, 6 kA","metaDescription":"ABB S202M-C4 miniature circuit breaker, 4 A, Trip Curve C, 2-pole, 277 VAC / 125 VDC, 6 kA interrupting capacity.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["2-Pole MCB (DIN Rail)"],"specifications":{"Amps":"4","Type":"Trip Curve C","Poles":"2","title":"S202M-C4","Mounting":"DIN Rail","Volts AC":"277","Volts DC":"125","description":"ABB S202M-C4 S200M MCB 230V 2 POLE|ABB S202MC4 S200M MCB 230V 2","lifecycle_stage":"current","Interrupt Rating AC":"6 kA","Interrupt Rating DC":"10 kA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$24.13","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/27262a57249b264d71ea0c2295e6c02d.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy the S202M-C4 and get a price?","answer":"The S202M-C4 is sourced through independent distribution."},{"question":"Will the S202M-C4 drop into a panel specified for S202M-C10?","answer":"Yes — same 2-pole DIN-rail footprint, same voltage ratings, same interrupting capacity.
