Basic soft starters

Stellar SR33 series

12/01/2011


The Stellar SR33 Series basic soft starters are designed for applications where traditional across-the-line starting or wye-delta starting would typically be appropriate. The SR33 semi-conductor soft starters, available in 22A to 482A sizes, are suitable to control three-phase ac induction motors with a wide variety of motor loads. Ideal for applications such as pumps, blowers, and conveyors, the SR33 series soft starters use thyristors for controlled reduced voltage motor starting and stopping, and then switch to internal contacts for efficient running at rated speed.
