ABB PSR6-600-70 1SFA896104R7000 Softstarter 6.8 A 200-600V AC

ABB PSR6-600-70 (article 1SFA896104R7000) is a compact three-phase softstarter rated at 6.8 A with a wide operating voltage range of 208...600 V AC. It achieves controlled motor acceleration and deceleration through a two-phase voltage ramp, and is suited to small three-phase motors with nominal currents from 3 to 105 A at up to 100 starts per hour.

Technical specifications:

• Series: PSR6-600-70
• ABB article number: 1SFA896104R7000
• EAN: 7320500338209
• Type: Softstarter
• Rated current: 6.8 A
• Rated maximum operational current: 6 A
• Operating voltage: 208...600 V AC
• Rated control voltage: 100...240 V AC, 50/60 Hz
• Motor nominal current range: 3...105 A
• Maximum starts per hour: 100
• Control method: Two-phase voltage ramp (soft start and stop)
• Relay output: RUN signal, normally open (NO)

Features and benefits:

• Built-in bypass reduces wiring effort and eliminates energy losses through the softstarter once the motor reaches full speed
• Two-phase voltage ramp control provides smooth acceleration and deceleration, limiting mechanical shock on connected equipment
• Three front-mounted potentiometers make start and stop ramp time adjustment straightforward without additional tooling
• RUN relay output in normally open state allows the unit to signal run status directly to an external control circuit
• Compatible with ABB manual motor starters via dedicated connection kits; optional Fieldbus communication supported through an external adaptor and Fieldbus plug

Applications:

• Pump systems where controlled starting prevents pressure surges in pipework
• Fans and ventilation units requiring gradual ramp-up to full speed
• Compressors where reducing startup mechanical stress extends service life
• Conveyors needing smooth, controlled starts to protect drive components and transported loads
