It interrupts faults up to 10 kA at 240 VAC — that's the SCCR for the branch circuit it protects, so it clears a hard short without upstream breakers needing to trip.
The S401M-C10 shares the same 10 A, Curve C, 1-pole DIN-rail footprint as the S201M-C10, but the S401M-C10 carries a higher interrupting rating — 10 kA vs. 6 kA at 240 VAC.
10 kA at 240 VAC, which is the short-circuit current it can safely clear without damage to itself or downstream equipment.
Yes, the S401M-C10 shares the same 1-pole DIN-rail footprint, 10 A rating, and Curve C trip characteristic as the S201M-C10. The main difference is the interrupting rating — 10 kA vs. 6 kA — so it's a direct mechanical and electrical replacement as long as the panel's available fault current doesn't exceed 10 kA.
