Frequently asked questions
Where can I buy S203MR-K1 and how do I get a price?
The S203MR-K1 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 estimate.
What is S203MR-K1's listed part number?
The listed part number is S203MR-K1.
Will S203MR-K1 drop into a panel that was specified around S204M-C16 without rewiring?
Both are ABB molded case circuit breakers in the same category, so the DIN-rail footprint and terminal layout are likely similar. But the S204M-C16 is a 4-pole unit (S204 prefix) while the S203MR-K1 is 3-pole (S203 prefix) — verify the pole count matches your panel wiring before assuming a direct swap.
