ABB PSR9-600-70 1SFA896105R7000 Softstarter 9 A 200-600V AC

The ABB PSR9-600-70 (article 1SFA896105R7000) is a compact softstarter for small three-phase motors. It controls motor acceleration and deceleration through a two-phase voltage ramp, with a rated operational current of 9 A and a wide operating voltage range of 208 to 600 V AC. A built-in bypass and three front-mounted potentiometers make installation and commissioning straightforward.

Technical specifications:

• Series: PSR9-600-70
• ABB article number: 1SFA896105R7000
• EAN: 7320500338223
• Rated maximum operational current: 9 A
• Operating voltage: 208...600 V AC
