Description
Motor Starting Auto Transformer Designed to reduce high starting current and starting torque in AC motors during start-up, preventing voltage drop on the supply line and protecting other connected equipment. Ideal for motors requiring low starting voltage and smooth operation. Suitable for medium-duty applications such as fans, pumps, and similar loads. Recommended by New Mass for reliable and stable motor starting.
