ABB S283UX-K10 Molded Case Circuit Breaker, Current Lifecycl

Lifecycle status is current — the manufacturer still lists it as an active catalog number. No PCN or EOL notice on record. That's the kind of supply certainty that keeps a storeroom bin from turning into a dead-shelf special. If you're holding a panel spec that calls out S283UX-K10, you're not looking at a forced redesign.
