Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
What is the closest functional second-source for S281-K6A?
The ABB S273-K6A is a three-pole version in the same S200 series family. For a single-pole 6A application, the S281-K6A is the correct form factor — the S273-K6A is a different pole count and won't drop into the same panel space without rewiring.
