Technical Info for Full Featured 3-Phase Soft Starters (SR55 Series, 17A - 477A)
Need help selecting a soft starter? Use our selector tool to configure and order.
Soft starters lower energy use and reduce wear and tear on motors and connected mechanical equipment. Fully digital, the Stellar SR55 series starters use thyristors for reduced voltage starting/stopping, have automatic configuration, built-in bypass relays, and a patented iERS system that reduces energy costs when used on lightly-loaded or oversized motors.
