SS1B08-20PN (230V, 50/60Hz, 08-20 FLA)
This product has been developed specifically to soft start large single phase rotary or piston/reciprocating 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 5 horse power electrical
- Reduces locked rotor amperage (LRA)/inrush current up to 50% 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
