Frequently asked questions

Where can I buy the S281-NA-B20 and get current pricing?

The S281-NA-B20 is sourced and quoted to order against an RFQ. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.

Will the S281-NA-B20 drop into a panel specified for the S273-K40A?

No, the S273-K40A is a wider multi-pole MCB (0.45 kg) with a K-curve at 40 A, while the S281-NA-B20 is a single-module B-curve unit at 20 A. They share DIN-rail mounting but differ in pole count, trip curve, and current rating — panel rework is required.
