What the ratings mean for fit
The XT4HU3200AFJ000XXX: The 250 A frame size and TMF 200-2000 trip unit mean this breaker is sized for motor circuits, feeder protection, or panelboard mains where the continuous load falls within the adjustable trip range. The TMF (thermal-magnetic fixed) curve provides inverse-time overload protection and instantaneous short-circuit response — standard for general-purpose distribution in industrial panels. The UL/CSA listing confirms it meets North American code requirements for branch-circuit protection.
Deployment context
Mounts in a standard panel or enclosure on a DIN rail or direct-mount plate. The front terminals simplify wiring in a panelboard or motor control center bucket. The 3-pole configuration suits three-phase loads — motors, pumps, conveyors, or lighting panels. The UL/CSA mark means it is accepted in North American industrial and commercial installations without additional agency review.
