What it is and where it sits
The ABB ACS580-01-246A-4 is a wall-mount frequency converter in the ACS580-01 frame, rated for 380-480 V three-phase at 50/60 Hz input. Cabinet envelope runs 39.3 cm x 30.0 cm x 96.5 cm (L x W x H), with an IP21 degree of protection — a chassis-rated, indoor-style enclosure that belongs on the back wall of a control room, not outdoors. At 69 Kg net (71 Kg shipping), this is a two-person lift onto the wall brackets — worth confirming the mounting anchors before the box arrives, not after.
Ratings that drive the BOM line
The supply rating is 380-480 V three-phase at 50/60 Hz, which sets the upstream breaker coordination and the motor's nameplate voltage — anything outside that window is the wrong drive for the line. Control-side I/O is two analog inputs and two analog outputs — enough for a closed-loop process variable and a speed reference, modest by industrial standards, so count channels before specifying extra I/O cards.
Where the class earns its keep
ACS580-01-class converters are wall-mount drives used on 380-480 V three-phase industrial lines for pumps, fans, and conveyors, with the 246 A frame size aimed at high-current motor loads in that category.
Same-family peer for second-source review
The older-generation ACS355-03E-38A0-4 is a fundamentally smaller machine — an IP20 chassis at 6 Kg shipping with a 38 A output rating — and is not a frame-for-frame cross to the ACS580-01-246A-4; it belongs in the conversation only as a legacy install reference, not as a substitute.
