SS1B16-32SN (230V, 50/60Hz, 16-32 FLA)

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
