ABB PSR12-600-70 1SFA896106R7000 Softstarter 12 A 200-600V AC

ABB PSR12-600-70 (article 1SFA896106R7000) is a compact softstarter rated at 12 A for small three-phase motors, covering an operating voltage range of 208...600 V AC. It achieves smooth motor acceleration and deceleration through a two-phase voltage ramp, reducing mechanical stress on the motor and driven equipment. The control voltage spans 100...240 V AC at 50/60 Hz, and a built-in bypass engages once the motor reaches full speed to save energy and simplify the installation.

Technical specifications:

• Series: PSR12-600-70
• ABB article number: 1SFA896106R7000
• EAN: 7320500338247
• Rated maximum operational current: 12 A
• Operating voltage: 208...600 V AC
• Control voltage: 100...240 V AC
• Frequency: 50/60 Hz
• Control method: Two-phase voltage ramp soft start and stop
• Motor range (nominal current): 3...105 A, three-phase
• Maximum starts: up to 100 per hour
• RUN output: Relay, normally open (NO)
• Adjustment: Three front-mounted potentiometers for start ramp, stop ramp, and time

Features and benefits:

• Built-in bypass simplifies wiring and eliminates softstarter losses once the motor is running at full speed
• Three potentiometers on the front panel allow straightforward on-site adjustment of start and stop ramp and timing without additional tools
• Relay RUN output in normally open state provides a ready-made motor status signal for control circuits
• Mechanical connection kits are available for direct pairing with ABB manual motor starters (MMS)
• Optional Fieldbus communication can be added via an external adaptor and Fieldbus plug for integration into automation systems

Applications:

• Centrifugal and submersible pumps where surge-free starting protects pipework
• Fans and ventilation units requiring gradual speed ramp-up
• Compressors that benefit from reduced inrush current on each start cycle
• Conveyors and belt systems where smooth starts prevent load shifting
