The SR33 series semi-conductor solid state soft starters provide many advantages when used instead of electro-mechanical contactors to control 3-phase AC induction motors:
22A to 482A Rated Current Versions @ 208230/460 VAC
Five Trip Classes: Class 5, 10B, 10, 20, 30
The SR33 series motor soft starters use thyristors for controlled reduced voltage motor starting and stopping, then switch to internal contacts for efficient running at the rated speed
They are designed to fit in place of existing wye-delta starters.
