What the DIN-rail mount means for your panel
That's the standard for control-panel branch protection across industrial and commercial gear. If your panel already has a DIN rail for terminal blocks or contactors, this drops in alongside them.

Frequently asked questions
Where can I buy the S283-K25W and how is it quoted?
The S283-K25W is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no stock count or price is listed here.
What is the S283-K25W's weight?
The listed weight is 0.41 kgs.
Will the S283-K25W drop into a panel specified around the S273-K40A?
Both are DIN-rail-mount supplemental protectors from ABB's S-series, so the physical footprint and rail mounting are the same. The S273-K40A is a 3-pole 40 A unit; the S283-K25W is a different rating. Check the specific current and pole configuration against your panel's branch circuit requirements before swapping — the rail fit is identical, but the protection curve and interrupting rating may differ.
