The part on the BOM line
The ACS510-01-038A-4 is a wall-mounted inverter drive specified for 380 - 480 V supplies at 50 - 60 Hz. At 18.5 Kg in a 45 cm x 27 cm x 60 cm wall-mount chassis, this is a two-handle install — plan the wall anchors and the lift path before the unit lands on site, especially on retrofit jobs where the existing mounting surface was sized for a lighter legacy drive.
What the ratings decide for the buyer
The 380 - 480 V window at 50 - 60 Hz is the supply band on this drive, covering three-phase industrial feeds within that voltage range without an external transformer. Wall-mount format on this frame means the unit is intended as a free-standing panel-side or wall-anchored installation rather than a through-door cubicle mount — the wireman should confirm gland plate sizing against the 27 cm width before specifying cable entry hardware, since the chassis width drives the bend radius available behind the terminal cover.
Handling, footprint, and panel layout
Shipping weight lands at 20 Kg against the 18.5 Kg bare unit figure, which is the packaging-and-pallet mass the receiving bay needs to plan around — once on the wall, the 18.5 Kg figure is what the anchor calculation should be run against. The 45 cm x 27 cm x 60 cm envelope leaves the typical ACS510 clearances for top and bottom airflow, so the install should preserve the manufacturer-specified breathing space rather than packing the drive into a sealed corner of the panel — fan-cooled inverters derate quickly when the intake path is restricted.
