The 10 kA DC rating exceeds the AC figure, which is typical for a single-pole DC break where the arc extinguishes more readily. If you're protecting a DC bus or a battery-backed control circuit, this breaker covers that application without needing a separate DC-rated device. ## DIN rail integration The 3-pole form factor fits three-phase subfeeds or single-phase circuits where you need a common-trip disconnect on all poles. Terminal capacity accepts up to 25 mm² conductor, per S200M series standard.","metaTitle":"ABB S203M-C6 S200M MCB, 6 A, Trip Curve C, 3-Pole, DIN Rail","metaDescription":"ABB S203M-C6 S200M miniature circuit breaker, 6 A rated, trip curve C, 3-pole, 277 V AC / 125 V DC, 6 kA interrupting rating AC.

We source the S203M-C6 through independent distribution and confirm current pricing and availability at quote time — no automated stock figure here, but a real-time quote on request."},{"question":"Will the S203M-C6 drop into a panel specified for the S203M-C50?","answer":"Yes, same physical footprint — both are 3-pole S200M series breakers on DIN rail, same terminal layout and width. The only difference is the current rating: 6 A vs 50 A. If the panel was designed for 50 A branch circuits, dropping in a 6 A breaker would under-protect the conductors unless the load and wire size are also changed. The mechanical fit is identical; the electrical coordination is what you need to verify."},{"question":"What compliance documentation does ABB provide for the S203M-C6?","answer":"ABB provides a Declaration of Conformity covering the S200M series, including the S203M-C6. The series carries CE marking, UKCA, and is designed to meet IEC/EN 60898-1 and IEC/EN 60947-2. RoHS and REACH compliance statements are available on request. Specific UL/CSA listings vary by variant — confirm with the datasheet for the exact certification mark on your unit."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/abb/S203M-C6","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/abb/S203M-C6 when reusing this data.
