Why Choose the ABB PSR6-600-70 Softstarter?
The ABB PSR6-600-70, order code 1SFA896104R7000, is a compact and dependable motor softstarter designed for controlled starting and stopping of three-phase asynchronous motors. 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 control with adjustable voltage ramps to provide smooth acceleration and deceleration. Its integrated bypass reduces power losses during continuous operation, while three front-mounted potentiometers simplify adjustment of the start ramp, stop ramp and initial or end voltage.
With a rated operational current of 6.8 A, an operational voltage range of 208–600 V AC and a control supply voltage of 100–240 V AC, the PSR6-600-70 supports motors rated up to 3 kW at 400 V. Its compact IP20 enclosure is suitable for installation inside industrial control panels.
Key Advantages
- Compact softstarter for three-phase asynchronous motors.
- 6.8 A rated operational current for small industrial motor applications.
- 208–600 V AC operational voltage range supports varied power systems.
- Built-in bypass reduces heat generation and power losses during operation.
- Adjustable voltage ramps reduce starting current and mechanical shock.
- Simple front-mounted potentiometers support fast commissioning.
Key Features
- ABB PSR compact softstarter series.
- 6.8 A rated operational current.
- 208–600 V AC rated operational voltage.
- 100–240 V AC control supply at 50/60 Hz.
- Two-phase controlled motor starting and stopping.
- Integrated bypass for efficient continuous operation.
- Adjustable start ramp, stop ramp and initial or end voltage.
- Normally open RUN signal relay output.
Controlled Motor Starting for Industrial Machinery
Softstarters such as the ABB PSR6-600-70 progressively increase the voltage supplied to a motor during start-up. This limits inrush current and torque peaks, helping protect electrical networks, motors, couplings, belts and other mechanical components.
The adjustable stop ramp can provide a smoother shutdown where an abrupt stop could cause mechanical shock or process disruption. Suitable external overload and short-circuit protection must be provided because the PSR6-600-70 does not include an integrated electronic motor overload.
Typical Applications
- Small pumps and pumping systems.
- Fans and ventilation equipment.
- Conveyors and material handling machinery.
- Compressors and workshop equipment.
- Packaging and production machinery.
- Industrial control panels and OEM automation systems.
