The ABB XT2HU3015AFF000XXX is a 15 A, 3-pole molded case circuit breaker from the XT2H frame. 15 A is the continuous current rating — sized for a 15 A feeder or branch circuit, not for a motor load drawing 15 A continuous (a motor circuit would need the breaker sized per the full-load amps plus startup, typically the next frame up). Rated 480 V AC, so it lands in 480Y/277 V or 480 V delta distribution panels. The 65 kA interrupting rating at 480 V means it can safely clear a fault up to 65,000 A without rupturing — critical for high-fault-capacity industrial switchboards where the available fault current exceeds 25 kA. Panel mount, so it bolts into a switchboard or MCC bucket; no DIN-rail adapter.
Deployment context
Panel-mount design so it lands in a switchboard or motor control center bucket, not on a DIN rail. Typical use: feeder protection in 480 V industrial distribution — lighting panels, small motor branch circuits, or general-purpose power panels where the 15 A rating matches the load and the 65 kA SCCR satisfies the fault-current study.
