ABB PSE142-600-70 1SFA897110R7000 Softstarter 143 A 200-600V AC

ABB PSE142-600-70 (article 1SFA897110R7000) is a general-purpose softstarter for three-phase motors covering a nominal current range of 18 to 370 A. It delivers controlled soft starting and stopping to limit mechanical and electrical stress, with a rated maximum operational current of 142 A and an operating voltage spanning 208 to 600 V AC.

Technical specifications:

• Series: PSE142-600-70
• ABB article number: 1SFA897110R7000
• EAN: 7320500400685
• Rated maximum operational current: 142 A
• Operating voltage: 208...600 V AC
• Rated control voltage: 100...250 V AC, 50/60 Hz
• Control method: two-phase
• Start/stop ramp: voltage ramp or torque ramp (selectable)
• Built-in bypass: yes
• Relay outputs: RUN, TOR, Event - normally open (NO)
• Protection functions: current limit, kickstart, analog output, EOL, underload, locked rotor
• Display: illuminated symbol display (language neutral)
• Optional external keypad: IP66 rated
• Communication: hardwire inputs (Start/Stop, fault Reset), built-in Modbus RTU, external fieldbus adaptor

Features and benefits:

• Built-in bypass removes the need for a separate bypass contactor, simplifying panel installation and reducing energy draw during steady-state motor operation
• Selectable voltage or torque ramp gives precise control over acceleration and deceleration to match the requirements of the driven load
• Integrated protection suite - current limit, EOL, underload, and locked rotor - reduces the need for additional external protection devices
• Modbus RTU fieldbus communication is built in as standard, with support for an external adaptor to connect to other automation networks
• Language-neutral illuminated symbol display simplifies commissioning across regions; the optional IP66 external keypad enables remote operation in demanding environments

Applications:

• Pumps - gradual ramp-up prevents water hammer and reduces pipeline stress at startup
• Fans and ventilation units - smooth acceleration extends belt and bearing service life
• Compressors - controlled start protects mechanical couplings and reduces peak current draw
• Conveyors - soft start and stop prevent sudden load jolts and product spillage
