Sourcing and lifecycle
Lifecycle stage is marked as current, meaning the S203MR-K10 remains in ABB's active catalog and is not subject to a last-time-buy or phase-out notice. This part is sourced to order against an RFQ through independent distribution channels; availability and current pricing are confirmed at quote time.
Panel integration
As a molded case circuit breaker in the S200 family, the S203MR-K10 is designed for DIN-rail mounting inside standard distribution enclosures. Its modular width allows straightforward grouping with other S200-series breakers and accessories on the same rail, simplifying panel layout and busbar alignment.
