ABB ACS550-U1-06A9-4 Variable Frequency Drive

ABB ACS550-U1-06A9-4 Variable Frequency Drive is a three-phase, low-voltage drive built to govern a 3-phase motor in 380–500 V networks. With a 2.2 kW (3 HP) rating and a nominal current of 6.9 A, it delivers stepped speed control for a range of industrial loads while maintaining robust protection and simple configuration. The unit’s enclosure is IP21-NEMA1, intended for indoor, wall-mounted installation, and it supports mounting options with direct-connect wiring and bottom or side conduit entries to fit confined control panels. Designed for 48–63 Hz electrical infrastructure, the ACS550-U1-06A9-4 belongs to ABB’s ACS550 family, a general-purpose drive used to implement simple, reliable motor control for applications such as conveyors, pumps, or fans in manufacturing environments. This model emphasizes straightforward setup, reliable performance, and compatibility with standard 3-phase 380–500 V systems, making it a common choice for replacing older drives or upgrading motor control with a compact, documented device from a leading automation supplier.
