Rated for 277 VAC and 500 VDC, with an interrupting capacity of 6 kA on the AC side and 10 kA on the DC side. The DC rating matters for battery-backed control circuits or solar combiner boxes — 10 kA at 500 VDC is a serious interrupting capability for a 2-pole frame. Mounts on standard DIN rail — snaps onto the 35 mm profile in the panel, same footprint as every other S200MUC pole. Two poles wide, so it occupies two module positions on the rail. If you're swapping an existing 2-pole breaker in a distribution board, the S202MUC-C10 drops in with no adapter plate.

Frequently asked questions
What is the interrupting capacity of the S202MUC-C10?
The S202MUC-C10 has an interrupting capacity of 6 kA at 277 VAC and 10 kA at 500 VDC. That 10 kA DC rating is notable for a 2-pole breaker — it handles battery-backed control circuits or solar combiner faults without cascading.
Where can I buy the S202MUC-C10?
The S202MUC-C10 is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm commitment.
What does the C-curve mean on the S202MUC-C10?
Trip curve C means the magnetic trip operates at 5 to 10 times the 10 A rated current. It holds through motor inrush and transformer energization but clears a hard short fast — the standard choice for general-purpose distribution and moderate inductive loads.
