Soft Starters
Soft Starters
A soft starter is a device used to temporarily reduce load and torque during motor startup.
A motor typically draws inrush current up to 10 times higher than their running current during startup, and up to 3 times higher torque. This kind of mechanical stress dramatically reduces the motor’s service life, and the large power draw can propagate to other equipment in the system. Soft starters are designed to eliminate these undesired side effects of motor startup.
Soft starters reduce starting torque by temporarily reducing voltage or current input, allowing the motor to accelerate smoothly. Soft starters are also able to control motor deceleration, reverse motor direction, and provide overload protection. They are an ideal alternative to drives where a more cost-effective, simple solution is required.

The S751 is also designed to be a complete package combining the SCR devices, bypass contactor and overload in one, very compact package. The S751 comes complete with everything needed to set up and program the soft starter.
Designed to be the smallest, most compact soft starter in the world today, the S751 is designed to fit in place of your existing soft starter or across-the-line NEMA or IEC starter today. Designed to work with 3-phase motors from 200 - 600V AC, the S751 combines the overload and bypass contactor into one package for fast and easy installation. The unit also provides all necessary overload protection for the motor. The built-in bypass contactor ensures a minimal amount of heating internal to the enclosure. The unit provides for smooth starting and stopping of motors to reduce both mechanical and electrical shock to the system. Short circuit protection can be provided by fuses.
