The 800 A rating is the breaker's continuous current capacity at 40 °C — it's sized for the main feeder or a large motor branch, not for a downstream distribution panel. The 3-pole configuration covers three-phase systems; the frame size matches the amp rating, so there's no derating headroom for ambient temperature above 40 °C without consulting the thermal curve. That means you can coordinate selectivity downstream — set the short-time delay to ride through motor start inrush without nuisance tripping, while the instantaneous still clears a hard fault fast. The LS/I variant omits ground-fault protection; if you need GF, you'd look at the LS/G version in the same frame. ## Where this class of breaker fits in a system Molded case circuit breakers like this one are the backbone of industrial power distribution — they sit between the transformer secondary and the switchboard, feeding motor control centers, panelboards, or large single loads. The Tmax XT6H series is ABB's high-performance MCCB line, designed for selective coordination in 600 VAC systems. The 800 A frame and electronic trip make it a fit for main breakers in 480 V or 600 V switchgear, where you need adjustable trip curves to coordinate with downstream feeders.","metaTitle":"ABB XT6HQ3800EFF000XXX Tmax XT6H MCCB, 800A 3P 600VAC","metaDescription":"ABB Tmax XT6H molded case circuit breaker, 800 A, 3-pole, 600 VAC, 800 A frame, E.DIP LS/I trip unit.
