STELLAR™ SR33 Series Basic 3-Phase Soft Starters


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 @ 208–230/460 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.
STELLAR™ SR33 Series Basic 3-Phase Soft Starters

 Stellar SR33 series basic reduced voltage soft starter - 22ASR33-22 Stellar SR33 series basic reduced voltage soft starter - 22A
208-230/460 VAC, for 3-phase motors (two phases controlled), rated for 10 starts/hour; footprint comparable to a Star-Delta starter. Three potentiometers control settings for: Start Time, Starting Voltage, and Stop Time (ramps down motor voltage, but does not apply braking torque to a load). Unit may require derating for applications other than fans and pumps; see specifications for appropriate derating. Unit requires 24VDC control voltage. Installation instructions included.
