Frequently asked questions
How do I get current pricing and availability for S281-K40A?
S281-K40A is sourced to order against an RFQ through independent distribution. Submit a request for quote; availability and current pricing are confirmed at quote time.
Will S281-K40A drop into a panel that was specified around S273-K6A without rewiring?
Both are ABB DIN rail MCBs, but the S273-K6A is a three-pole 6 A unit (0.36 kg) while the S281-K40A is a single-pole 40 A unit (0.14 kg). The pole count and current rating differ, so the panel wiring and busbar arrangement would need to match the single-pole 40 A configuration.
