What the code buys you
The ACS550-U1-096A-4 is the 75HP 480V variant in the ACS550-U1 wall-mount family. The drive lists at 19.96 kgs, so panel-side handling is a two-person lift into the cabinet and the mounting footprint needs to be reserved before the gland plate is cut.
Sizing and application fit
On a 480 V three-phase bus the 096A frame maps to roughly a 75 HP induction motor at normal-duty operation; that is the number that should drive the BOM line, not a higher marketing peak figure. For constant-torque loads the heavy-duty current rating governs, not the HP figure alone; confirm the HD ampere value against the application before sizing the drive.
Mounting, wiring, EMC posture
Cable run from drive output to motor must be checked against the ACS550 reflected-wave limits before commissioning. Grounding is single-point at the drive end of the motor cable — the field-end ground is the path that injects common-mode noise into the analog reference and trips insulation monitoring unexpectedly. The ACS550-U1 takes its place in the cabinet as a panel-build item: reserve DIN-side clearance for the keypad removal, line-side breaker or fused disconnect upstream of the rectifier, and the brake chopper resistor on the bus if vertical-load or short decel profiles are in scope.
Lifecycle and sourcing posture
The ACS550 platform has been succeeded by the ACS580 family in ABB's catalog; the ACS580-01-065A-4 sits in the same general-purpose slot at a lower ampere frame and is a planning reference for a migration line, not a literal drop-in for a 096A-4 panel.
