Why Choose the ABB PSR3-600-70 Softstarter?
The ABB 1SFA896103R7000, product designation PSR3-600-70, is a compact and reliable three-phase motor softstarter designed to provide controlled starting and stopping of industrial AC motors. As part of the ABB PSR softstarter range, it helps reduce electrical starting current and mechanical stress on motors, couplings and driven equipment.
This softstarter uses two-phase voltage-ramp control to progressively increase the motor voltage during starting and reduce it during stopping. Its integrated bypass helps reduce power losses during normal operation, while three front-mounted potentiometers provide straightforward adjustment of the start ramp, stop ramp and initial voltage.
With a rated operational current of 3.9 A, an operating-voltage range of 208–600 V AC and a 100–240 V AC control supply, the PSR3-600-70 supports motors rated up to 1.5 kW at 400 V. Its compact IP20 design is suitable for installation inside industrial control panels.
Key Advantages
- Controlled soft starting and soft stopping of three-phase motors.
- Reduces electrical starting current and mechanical stress on driven equipment.

Controlled Motor Starting for Industrial Machinery
Direct-on-line motor starting can produce high inrush current and sudden mechanical torque. The ABB PSR3-600-70 progressively applies voltage to the motor, providing smoother acceleration and helping reduce stress on belts, gears, couplings and other driven components.
The adjustable soft-stop function can provide more controlled deceleration where an abrupt stop is undesirable. The PSR3-600-70 should be combined with suitable external motor overload and short-circuit protection selected for the motor and installation.
Typical Applications
- Small industrial pumps and fans.
- Conveyors and material-handling equipment.
- Compressors and processing machinery.
- Packaging and production equipment.
- Motor-control panels and starter assemblies.
- OEM automation systems and machine building.
