Frequently asked questions

Will S283UC-K50 drop into a panel wired for S273-K4A?

Yes, for the mechanical fit. Both share the same DIN-rail subcategory and similar weight (0.40 kg vs 0.38 kg). The electrical rating differs — S283UC-K50 is 50 A versus the S273-K4A's lower rating — so verify the branch circuit ampacity before substitution.
