Why Choose the ABB PSR25-600-70 Softstarter?
The ABB PSR25-600-70, order code 1SFA896108R7000, is a compact two-phase-controlled softstarter designed for smooth starting and stopping of three-phase motors. As part of the ABB PSR compact softstarter range, it reduces electrical starting current and mechanical stress on motors, couplings, belts and driven machinery.
This softstarter combines voltage-ramp control with a built-in bypass, reducing power losses during normal operation while saving installation space. Three front-mounted potentiometers provide straightforward adjustment of the start ramp, stop ramp and initial or end voltage, while Run and Top of Ramp relay outputs support status monitoring.
With a rated operational current of 25 A, an operational voltage range of 208–600 V AC and an IEC motor rating of 11 kW at 400 V, the PSR25-600-70 is suitable for pumps, fans, compressors, conveyors and other industrial machinery. Its 100–240 V AC control supply enables integration into a broad range of industrial control systems.

Reliable Soft Starting for Industrial Motors
Softstarters such as the ABB PSR25-600-70 gradually increase the voltage supplied to a motor during starting. This limits starting current and torque peaks, helping reduce voltage disturbances, mechanical shock and wear throughout the driven system.
The PSR range can be combined with an ABB manual motor starter to create a compact solution incorporating soft start, soft stop, overload protection and short-circuit protection. Its built-in bypass, status relays and simple potentiometer settings make it suitable for machine builders, panel builders and industrial maintenance teams.
Typical Applications
- Pumps and water-handling equipment.
- Fans and ventilation systems.
- Compressors and process machinery.
- Conveyors and material-handling equipment.
- Machine tools and production systems.
- Industrial control panels and OEM machinery.
