It's a current-production part, so it's still a standard line-item on a BOM — no last-time-buy scramble.
Rated at 16 A, this MCB sits in the middle of the K-curve range — the K characteristic means it's built for motor and inductive loads where inrush can hit 8–12× rated current without nuisance tripping. It's the go-to for protecting contactor coils, solenoid valves, and small transformer primaries in a panel.
Lifecycle status is current — ABB still lists this as an active catalog number. No PCN or EOL notice has been issued.
