Basic 3-Ph

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.

SR33-132 Stellar SR33 series basic reduced voltage soft starter, 132
Stellar SR33 series basic reduced voltage soft starter, 132A, 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. SR33-132 thru SR33-280 starters require insulation kit SR33-HS1 for UL installations. Installation instructions included.
