What this MCCB delivers on the line
The ABB XT1HU3030MFF000XXX is a 3-pole moulded case circuit breaker from the XT1H frame, rated 30 A continuous at 480 VAC. Its 65 kA interrupting rating at 480 VAC means it can safely clear a bolted fault up to that level without rupturing — essential for high-fault-capacity panels where upstream coordination matters. Panel-mount construction suits enclosure-based distribution boards, not DIN-rail snap-in.
