The 250 Series offers superb flexibility, reliability, and value. A general purpose, economical drive rated to 2HP, the 250 Series is our top-selling enclosed drive. Where most other drives require options to include soft start adjustment, AC line fuse protection and additional heat sink to handle higher HP motors, these are all included in every 253G model as standard features. Reliability is enhanced from the use of a rugged packaged power bridge. Chassis or NEMA 4/12 enclosure styles are available. Many options further extend the 250’s capabilities.

Typical applications include conveyors and material handling, process pumps and
machine tools.
