Product details

Panel integration note

The S401M-C10NP is a 1-pole miniature circuit breaker from the ABB S400 series, rated 10 A at 240 VAC with a Trip Curve C characteristic. DIN-rail mounting snaps into the standard 35 mm profile; the single-module width (roughly 17.5 mm per pole) keeps fill factor predictable in a crowded enclosure.

The 10 A continuous rating sets the maximum resistive load this breaker will carry without tripping under steady-state conditions. Trip Curve C means the magnetic trip activates at 5 to 10 times rated current — so for a 10 A breaker, instantaneous trip occurs between 50 A and 100 A. The 240 VAC rating is the maximum line-to-neutral voltage for a single-pole break; on a 120/240 V split-phase service, this breaker protects one leg.

Frequently asked questions

Where can I buy S401M-C10NP and get a price?

S401M-C10NP is sourced to order through independent distribution. Submit an RFQ for current pricing and availability — confirmed at quote time, no stock figures published here.

What are the key ratings for S401M-C10NP?

Rated 10 A continuous, 240 VAC, 1-pole, Trip Curve C, with a 10 kA interrupting rating per IEC 60898. Mounts on 35 mm DIN rail.

Will S401M-C10NP drop into a panel specified around S201MUC-K25?

No — S201MUC-K25 is a 2 A, Curve K breaker rated 277 VAC with a 6 kA interrupting rating. The S401M-C10NP is 10 A, Curve C, 240 VAC, 10 kA. Different trip curve, different interrupting capacity, and different current rating mean the two are not drop-in substitutes without recalculating the branch circuit protection.
