Overview

The Hammond Power 2909D1 Motor Starting Autotransformer is a 2-coil, 2A-series device engineered for three-phase industrial motor applications up to 100 HP at 600V. This autotransformer delivers reduced-voltage starting to minimize inrush current and voltage drop during motor startup, protecting electrical systems and extending motor lifespan. The 2-coil design improves energy transfer efficiency and reduces heat generation compared to single-coil alternatives, making it ideal for heavy-duty environments. With a 600V rating and compliance with industrial standards, the 2909D1 is optimized for reliability in applications such as pumps, compressors, and conveyors. Manufactured in the US by Hammond Power, this autotransformer ensures consistent performance in demanding industrial settings. The 2A-series design prioritizes precise voltage control and durability, reducing mechanical stress on motors during startup. Suitable for continuous operation, it meets UNSPSC 39121035 and is built to withstand harsh conditions.
