SS1B08-16SN (230V, 50/60Hz, 08-16 FLA)

Regular price $249.00

This product has been developed specifically to soft start large single phase scroll compressors and motors. It provides a dramatic reduction in the starting current but still provides full start torque. This will eliminate light flicker, reduce start-up noise, and extend the life of the motor or compressor. 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.

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
  • Provides motor reversal protection during short power outages
  • Internal delay timers prevents rapid cycling in fault conditions
  • Provides brownout protection
  • Self-testing diagnostics
