Types of Softstarters

We provide 3 ranges of ABB Softstarters, to cover your needs, secure motor reliability and longevity. The range includes;

  • PSR

  • PSE

  • PSTX

PSR - Softstarter

PSR Softstarter

PSR softstarters allow for the design of compact starting equipment, as they are the smallest of all softstarters. Combined with a manual motor starter, the PSR is far more compact than the star-delta starter, and thanks to a built-in bypass, there are fewer energy losses inside the softstarter.  This range includes a manual motor starter, (optional) connection kit, output signal relays, LED indicators, three potentiometres for settings and it can be screw or din-rail mounted.  Our softstarters range from 1.5-55kW power rating.

Typical applications include:

  • Bow thruster
  • Centrifugal pump
  • Compressor
  • Conveyor belt (short)
  • Elevator




PSE Softstarter

PSE specialises in pump operation in addition to meeting most water industry requirements. Compact design with built-in bypass combines the requested protections. Remote operation can be achieved with an external keypad or over a fieldbus.  This range includes a screw mounting. digital input for start, stop and reset and output signal replays for run, top ramp and event. Our softstarters range from 7.5-200kW power rating.

Typical applications include:

  • Bow thruster
  • Centrifugal pump
  • Compressor
  • Conveyorbelt (short)
  • Elevator
  • Escalator


Research and development of the PSTX are combined with knowledge of application-specific requirements and needs. New features and improved reliability are added with this latest ABB motor control & protection advancement.  This range has a three-phase control, an operational voltage between 208-690 VAC, a wide rated control supply voltage, PSTX rated operational current, in-line and inside-delta connection, coated circuit boards for protection, detachable keyboard IP66, graphical display, built-in bypass and modbus RTY, support for all major communication protocols and an analog output for measurement of current, voltage and power.  Our softstarters range from 15-710kW power rating.

Typical applications include:

  • Bow thruster
  • Centrifugal pump
  • Compressor
  • Conveyor belt (short)
  • Elevator

What Our Customers Say

Great over the phone help with issues and immediate engineer to site response - great service.

Oliver Schooler, June 2020

I spoke with Amy Finn who dealt with the break down support. She was superb. Understood my requirements and kept me updated throughout the process. The engineer resolved the problem promptly, also spares were made available if the problem was bigger than expected to mitigate any risk of having to wait for parts.

Malcolm Brown, May 2020

Great service from Billy, Brandon and Liam. They worked quickly and efficiently into the early hours to get our 800KW hire drive up and running. They also removed our damaged drives and took them away for repair. Got our plant producing saving us massive costs due to lost production. The engineers worked safely and calmly during a highly pressured period. Great work done by your guys!

Lee Armitage, March 2020

Thanks to Amy and Sam for their assistance last week. It's always really appreciated to know Quantum are at the end of a phone when we need you all to get us back up and running.
