Product details

That makes it a fit for inductive circuits where a standard C-curve breaker would drop out on startup surge.

How it compares to the S201M-C10

The closest functional peer is the S201M-C10 — also 1-pole, 10 A, DIN rail — but that part uses a C-curve (magnetic trip at 5–10× In) and is rated only 277 VAC / 60 VDC with a 6 kA interrupting capacity. The S281-K10's K-curve and 480 VAC rating give it a wider voltage envelope and better coordination on motor circuits. If your panel was specified around the S201M-C10, the S281-K10 will not drop into the same footprint without checking the voltage rating and trip coordination — same rail, same pole count, but different curve and voltage class.

Frequently asked questions

How do I get current pricing and availability for S281-K10?

The S281-K10 is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What is S281-K10's listed amps?

The S281-K10 is rated 10 A continuous.

What is S281-K10's trip curve type?

The S281-K10 uses Trip Curve K, with a magnetic trip threshold typically 8 to 12 times rated current, suited for motor and inductive loads.

Will S281-K10 drop into a panel specified around S201M-C10 without rewiring?

It shares the same 1-pole, 10 A, DIN rail format, so mechanical fit is the same. However, the S281-K10 is rated 480 VAC versus the S201M-C10's 277 VAC, and uses a K-curve instead of a C-curve. Check voltage rating and trip coordination before substituting — no rewiring needed if the circuit voltage is within the S281-K10's rating and the trip curve is acceptable.
