What the ratings mean for fit
The 1SDA060681R1: The 250 A frame and 3-pole configuration place this breaker in the main feeder or large subfeed role inside a 480 V panel. The thermal-magnetic trip gives instantaneous short-circuit response plus a thermal element for overload protection — no electronic adjustments, so it is a fixed-characteristic device suited to straightforward motor or distribution circuits where coordination studies are already done. The UL listing (AS mark) means it is accepted for US and Canadian installations without additional agency review — a standard requirement for panel OEMs shipping to North American sites.
Sourcing and lifecycle
Lifecycle stage is marked current, meaning ABB continues to manufacture this order code. No phase-out or last-time-buy notice is on record. For a BOM freeze or a new panel design, this part is a stable line item — no need to qualify a substitute unless the project requires a different trip curve or electronic trip unit.
Deployment context
Mounts in a standard panel enclosure on a DIN rail or direct-mount plate. The T4N frame size is common across ABB's molded case breaker line, so panel cutouts and bus-bar kits for this footprint are widely stocked.
