ABB Softstarters

Why Use a Softstarter?

By reducing inrush currents and limiting torque, softstarters protect your equipment, extend the life of your motor, and reduce motor heating. During start-up, softstarters provide gentle acceleration up to full speed, saving energy and reducing emissions.

Why Purchase Through Quantum?

As a drives and motors specialist, our specialist teams are here to help you from the purchase of your softstarter to its maintenance after installation.

1.5–55 kW power rating

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.

Features and installation

This range includes a manual motor starter, optional connection kit, output signal relays, LED indicators and three potentiometers for settings. It can be screw or DIN-rail mounted.

Typical applications

Bow thruster
Centrifugal pump
Compressor
Conveyor belt (short)
Elevator

7.5–200 kW power rating

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.

Features and installation

This range includes screw mounting, digital inputs for start, stop and reset, and output signal relays for run, top of ramp and event.

Typical applications

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

15–710 kW power rating

PSTX Softstarter

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 and protection advancement.

Features and installation

This range has three-phase control, an operational voltage between 208–690 VAC, a wide rated control supply voltage, in-line and inside-delta connection, coated circuit boards for protection, a detachable IP66 keypad, graphical display, built-in bypass and Modbus RTU, support for all major communication protocols and an analogue output for measurement of current, voltage and power.

Typical applications

Bow thruster
Centrifugal pump
Compressor
Conveyor belt (short)
Elevator

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!

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.
