Drawbacks of direct starting are as following:

-High inrush current: Heat, flicker risks, energy and installation costs
- Noise, arcs: Short control lifetime and maintenance costs
- High transient torque: Excessive wear of the coupling parts leading to maintenance costs
- Quality problems and product wastes may occur

A Solid State soft starter will then limit the starting current hence saving energy. It will at the same time limit torque for a longer lifetime of mechanical parts.

celduc® relais has designed a range of soft starters for AC motors up to 26 kW (wired in Delta).
