Carlo Gavazzi offers a range of motor controllers for soft starting/stopping, dynamic braking, and reversing of three phase squirrel cage motors. Applications include conveyor systems, pumps, compressors, industrial dryers, mixers, automatic doors, palletizers, and fans.

Our soft start controllers feature internal bypass relays which eliminate the need for large external heatsinks. This minimizes the space requirements in your panel and also greatly reduces the heat generated.

We also offer soft starters with built-in over temperature monitoring, thermal monitoring of motor via PTC sensor, and built-in overload protection (class 10 or class 20).

With the increasing use of geo-thermal energy and the rising cost of energy in HVAC systems in general, our range also includes single and three phase soft starters for scroll compressors in order to minimize the starting current and preventing light flickering.
