PRODUCT INFORMATION
Product Overview
The ABB ACS550-01-087A-4 is an ACS550 series AC drive designed for variable speed motor control. It operates on a three-phase input supply ranging from 380 V AC to 480 V AC. The unit provides an 87 A normal-use rating with an output capacity of 45 kW. For heavy-duty industrial applications, the drive delivers 72 A continuous current and 37 kW.
This wall-mounted unit utilizes an R4 frame size architecture with an IE2 efficiency class rating. The chassis meets IP21 and NEMA Type 1 environmental protection standards for dry indoor environments. Although discontinued by the manufacturer, this model remains widely deployed across industrial machinery.
