Overview

ABB ACS250 Series — Micro Drives | IP66/NEMA 4X for Harsh Environments:

Expanding the voltage range for ABB IP20 micro drives as well as offering a full voltage range of IP66 drives, the ACS255 drive provides more solutions for basic applications. IP66 drives are ideally suited for food and beverage applications like augers, mixers, conveyors, pumps and fans where the drives are exposed to dust, moisture, and chemicals. Feed-thru wiring in IP20 models facilitates replacing panel mounted motor starters. IP66 models are offered with and without front panel mounted operator controls: Disconnect, speed potentiometer, and FWD-OFF-REV selector switch.

ABB micro drive ACS255 with IP66/NEMA 4X enclosure is designed for applications such as; packaging machinery, mixers, pumps, fans and conveyors, which are installed in harsh environments containing dust, moisture and cleaning chemicals. The drive’s design and ease of setup benefit a broad range of industries.
