The fixed-trip design means the thermal-magnetic trip unit is integral — no interchangeable trip blocks to source separately, which simplifies BOM management for a panel builder. This part is in the current lifecycle stage, so it's still a standard catalog item, not a last-time-buy scavenger hunt. At 800 A and 600 VAC, this breaker is sized for the main incoming feeder or a large downstream sub-feed in an industrial distribution board. The 3-pole configuration covers three-phase loads — typical for motor control centers, large pump skids, or compressor banks. Mounting is standard for the Tmax XT6H frame size, so it fits the existing DIN-rail or panel-mount footprint of an ABB switchboard lineup. The 800 A frame gives you headroom for future load growth without swapping the entire breaker — the fixed trip is set at 800 A, but the frame itself is rated for that current continuously without derating concerns in a 40°C ambient.","metaTitle":"XT6HU3800DFF000XXX ABB Tmax XT6H 800A 3P Molded Case Circuit","metaDescription":"ABB Tmax XT6HU3800DFF000XXX molded case circuit breaker, 800A, 3-pole, 600VAC.
