The XT4LU3200MFF000XXX: The 200 A continuous rating (IU=200) sets the maximum uninterrupted current this MCP can carry without tripping. For a motor branch circuit, that means the full-load amps of the motor should be at or below 200 A — typically suiting a motor in the 100–150 HP range at 480 V, depending on service factor and starting characteristics. The 3-pole (3P) construction covers three-phase loads. The F F designation indicates the type of line and load terminals — fixed, front-connected lugs, which means it's designed for panel-mount bus bar or cable connections, not plug-in bases.
Lifecycle stage is current — ABB still manufactures this order code. No phase-out or last-time-buy notice is on record. For a procurement decision, that means the part is specifiable into new designs and available through standard distribution.
