Frequently asked questions
Where can I buy S273-K32A?
S273-K32A is sourced and quoted to order against an RFQ through independent distribution, with availability and current pricing confirmed at quote time.
What is the difference between S273-K32A and S273-K40A?
The S273-K40A is a 40A variant of the same S273 series, sharing the same K-characteristic curve and DIN-rail footprint. The only functional difference is the higher current rating; panel wiring and busbar connections must be sized for 40A if substituting.
