The S283-K4: Snap-on DIN rail mounting means it clips directly onto a standard 35 mm DIN rail inside the panel — no screws or brackets needed for the rail mount, though the load and line conductors terminate under the screw terminals as usual.

Frequently asked questions
Where can I buy S283-K4 and how do I get a price?
The S283-K4 is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.
Will S283-K4 drop into a panel that was specified around S273-K40A without rewiring?
Both are DIN-rail-mount miniature circuit breakers in the same ABB S200-family footprint, so the S283-K4 will physically clip into the same rail slot. However, verify the specific ratings (kA breaking capacity, curve type, number of poles) of your original S273-K40A against the S283-K4 to confirm electrical fit before swapping.
