ABB Soft Starters

The compact range, PSS03...25
covers motor currents from 3 to 25A and has the following advantages.

• Gives room for more products on a given mounting surface.
• Easy to install, the device is snapped onto a DIN mounting rail. Clear instructions are provided on the front.

The Flexible range, PSS18...300 for motor currents from 18 to 515A offers a solution possible to adapt to almost any applications

• With two connection possibilities, either in line with the motor or inside the motor delta. Can also be equipped with current limit.
• Easy to set up. With just three clearly labeled rotary switches on the front of the unit it is possible to adjust the soft starter for a wide range of applications.
• Solid state electrical circuit. This ensures the highest reliability and reduces maintenance to a minimum, even in applications with frequent starts and stops

The advanced range, The new PST30...1050 which besides many functionalities also speak your language. The range covers motor currents from 30 to 1810 A

• Advanced integrated protections.
• Flexible bus communication system. By using the ABB Field bus plug (FBP), you can decide at any time which bus system to select within the ABB FBP range. The interface between the PST soft Starter and the ABB FBP is always the same, independent of size and delivery date.
• LCD display: With 12 languages, a menu system similar to your mobile phone, preprogrammed application settings and automatic status and event logging, It couldn't be easier to set up and operator.
• Programmable signal relays: gives you several possibilities for signaling warnings, faults and other events. You can use these functions for two or three speed motors as well
• Integrated by-pass contractor. On the larger sizes (PSTB370...PSTB 1050), there is an ABB AF contractor integrated. This gives you advantages in terms of cost saving, space saving and last but not least energy saving. With a by-pass contractor you can reduce the power losses during normal run by 90% or more.
