Frequently asked questions
Where can I buy S203P-K10 and what is the lead time?
The S203P-K10 is sourced to order against an RFQ through independent distribution channels. Availability and current lead time are confirmed at the time of quotation — no stock count or shipping promise is stated here.
Will S203P-K10 drop into a panel specified around S273-K40A without rewiring?
Both parts are 3-pole DIN rail MCBs from ABB's System pro M family, sharing the same modular footprint and rail mounting. The S203P-K10 is a 10 A K-curve device; the S273-K40A is a 40 A K-curve device. Physical interchange is possible, but the current rating and curve must match the circuit design — verify the branch circuit protection requirements before substituting.
