Product details

Rated 6 A, Trip Curve C — what that means for the panel

DC capability and interrupting ratings

Rated for 125 V DC (per) with a 10 kA interrupting rating (per) — that DC rating is worth noting because not every MCB in this class carries a published DC interrupting capacity. 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.

Frequently asked questions

What is the S203M-C6 rated for?

Rated 6 A continuous, Trip Curve C, 3-pole, 277 V AC / 125 V DC, with a 6 kA interrupting rating at 277 V AC and 10 kA at 125 V DC (per,).

How do I get current pricing and availability for the S203M-C6?

Submit an RFQ through this listing. 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.

Will the S203M-C6 drop into a panel specified for the S203M-C50?

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.

What compliance documentation does ABB provide for the S203M-C6?

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.
