ABB PSR72-600-70 1SFA896113R7000 Softstarter 72 A 200-600V AC

The ABB PSR72-600-70 (article 1SFA896113R7000) is a compact softstarter designed for small three-phase motors, with a rated maximum operational current of 72 A and a wide operating voltage range of 208 to 600 V AC. It manages motor acceleration and deceleration through a two-phase voltage ramp, reducing inrush current and mechanical stress at start and stop.

Technical specifications:

• Series: PSR72-600-70
• ABB article number: 1SFA896113R7000
• EAN: 7320500362617
• Rated operational current: 72 A
• Operating voltage: 208...600 V AC
• Control voltage: 100...240 V AC, 50/60 Hz
• Motor nominal current range (PSR series): 3...105 A
• Maximum starts per hour: 100
• Control method: two-phase voltage ramp (soft start and soft stop)
• Relay output: RUN and TOR signals, normally open (NO)
• Start/stop ramp and time adjustment: three front-mounted potentiometers

Features and benefits:

• Built-in bypass simplifies installation and lowers energy consumption once the motor reaches full running speed
• Two-phase voltage ramp provides smooth, controlled acceleration and deceleration, reducing mechanical stress on the motor and driven equipment
• Handles up to 100 starts per hour, making it suitable for demanding duty cycles
• RUN and TOR relay outputs in normally open (NO) state allow straightforward integration with external control or monitoring circuits
• Three front-panel potentiometers for start ramp, stop ramp, and ramp time allow quick on-site commissioning without additional tools

Applications:

• Pumps
• Fans and ventilation systems
• Compressors
• Conveyors
