This product has been developed specifically to soft start large single phase compressors and motors. It provides a dramatic reduction in the starting current but still provides full start torque. It will automatically adjust itself to cover the range of 1.75 to 7 hp. It is fully self-contained in a conveniently small, double insulated and flame retardant enclosure. Contact us if you're interested in purchasing our products or need more information.

Sure-Start soft starters are ETL, CE and RoHS compliant.

Two Versions Available

• Primary - includes the function of the contactor

• Secondary - used in conjunction with an existing contactor

Features & Benefits

• Rated for motors between 1.75 to 7 horse power electrical

• Reduces locked rotor amperage (LRA)/inrush current up to 70% at start-up

• Eliminates light flicker

• Reduces start-up noise

• Avoids torque stress fracture on pipes

• Automatic optimization of motor start-up current

• Reduced stress and heating of compressor/motor therefore extending the life

• Allows systems to meet certain utility requirements

• Easy installation with supplied wiring (special wiring options available)

Motor Protection Functions

• Protects the compressor/motor from stalling at low voltages

• Delay function limits number of motor starts per hour

• Thyristor protected for long life (primary model only)

• No extra motor contactor needed (primary model only)

• Provides motor reversal protection during short power outages

• Internal delay timers prevents rapid cycling in fault conditions

• Provides brownout protectionSelf-testing diagnostics (primary model only)

  
  

Models
