Overview

The Hammond Power 3009C2.5 is a 3-coil autotransformer from the 3A-series, specifically engineered for industrial motor starting applications. Operating at a nominal voltage of 480V, this unit is rated to support motors up to 250 horsepower (HP). Its primary function is to facilitate reduced voltage starting for large industrial motors. This process significantly mitigates high inrush currents and minimizes voltage dips on the power distribution system during motor startup. By controlling the initial acceleration, the 3009C2.5 reduces mechanical stress on the motor, gearbox, and connected driven equipment, contributing to an extended equipment lifespan and improved operational reliability. The 3A-series autotransformers are constructed with industrial environments in mind, ensuring dependable performance under demanding conditions. By limiting the initial current draw, this autotransformer can also contribute to more stable power distribution within a facility, preventing cascading voltage sags. Its robust design ensures reliable operation for heavy-duty motor control. Manufactured in the USA, this autotransformer adheres to high manufacturing standards. The UNSPSC code for this product is 39121035.
