SureStart® - single phase
Give large compressors and motors a soft start and extend their lifetime
Achieve over 60% reduction in startup current for your AC unit and pumps with our range of single phase Surestart solutions.
This will eliminate light flicker, reduce start-up noise, and extend the life of the motor or compressor. Single phase soft starters are suitable for 1.75 to 7 horse power (hp) motors in the 220/230V models and are suitable between 0.75 to 1.75 hp for the 115V models.
Plus, all single phase models work in both 60Hz and 50Hz applications.
