RS PRO Three-Phase Soft Starter


Introducing the range of the RS PRO Soft Starters, ideal for protecting motors from stop/starts, reducing load, torque, electrical overload and overcurrent when the motor kickstarts, ensuring a long motor lifespan. The three-phase design offers a higher motor torque and lowers motor temperature rise which can be caused by long start-up ramps or higher torque applications, making it much more durable and hardwearing than standard two-phase control starter devices. The compact motor starters are easy to install, and ideal for use in a wide range of applications, thanks to superior performance.

Features and Benefits:


  • These RS PRO 3-phase control starters are ideal for ensuring optimum protection of motors when starting and stopping, as well as reducing load, torque and electrical surges

  • Starters are used primarily to ensure longer electric motor life by reducing the strain on the motor, as well as improving starting performance

  • Each of the soft starters has been designed with a built-in bypass contactor relay and offer a wide motor voltage range

  • These motor starters come with RS 485/Modbus RTU for Bus network monitoring and control

  • Control Voltage 100 – 240Vac

  • Available in DIN rail mount or backplate screw fixing for easy installation to a power supply

  • Suitable for use with devices such as fans, blenders, pumps, crushers, compressions, conveyors, screw presses and hoists

Applications:


Soft starters are a type of motor starter unit that are specifically designed to support motor circuits starting and stopping and picking up the load to reduce wear and tear, limiting production downtime which in turn keeps production levels up and lowers the amount of maintenance work. They also support limiting the torque and electrical surges on start-up, which means as a whole, the motors will have a much longer performance life. They are most commonly used in industrial manufacturing and engineering environments where things like conveyors, fans, compressors, pumps and much more.
