Product details

It's a current-production part (lifecycle stage: current), so it's still the standard line-item for new panel builds and BOMs.

What the C-curve means for your load

For a 25 A breaker, that's a magnetic trip threshold between 125 A and 250 A. This suits it for general-purpose loads with moderate inrush — think lighting banks, small motor circuits, and transformer primaries. If your load has a high inrush (welder, large motor), you'd step up to a D-curve; if it's purely resistive (heater), a B-curve gives faster protection. The C-curve is the middle ground, and the most common choice for mixed commercial/industrial sub-circuits.

Frequently asked questions

What is the S201M-C25NA's part number and weight?

The part number is S201M-C25NA, and the listed weight is 0.11 kg.

Where can I buy the S201M-C25NA?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

Will the S201M-C25NA drop into a panel specified around the SH201T-C16?

Both are DIN-rail miniature circuit breakers from ABB's S200 family, sharing the same physical footprint and mounting. The key difference is rating: the S201M-C25NA is a 25 A C-curve, while the SH201T-C16 is a 16 A unit. If your panel was wired for 16 A protection, swapping to a 25 A breaker without checking the downstream conductor sizing and load is not recommended. The mechanical fit is the same; the electrical coordination needs a review.
