ABB 1SFA898117R7000 PSTX570-600-70

Product Overview
The ABB PSTX570‑600‑70 soft starter is designed for medium to large three-phase motors. It supports a rated operational current of 570 A with operational voltage between 208 and 600 V AC 

Key Features

• Soft start and stop using voltage or torque ramp

• Integrated bypass for energy efficiency and reduced heat

• Built-in protection functions include electronic overload (EOL), current limit, kick-start, motor heating, pump cleaning, jog, dynamic and standstill braking, underload, locked-rotor, phase loss, and imbalance protection

• Detachable full-graphic user interface rated IP66 and NEMA 4X for outdoor use

Specifications

• Rated operational current (inline): 570 A; inside-delta up to 987 A

• Rated operational power: up to 400 kW at 500 V (inline), 700 kW inside-delta

• Control supply voltage: 100–250 V AC, 50/60 Hz; control circuit 24 V DC

• Dimensions (HxWxD): 493 × 361 × 282 mm; weight: 27 kg 

• Ramp time: 1–120 s; initial voltage start: 10–99 % 

• Operational temperature: −25 °C to +60 °C 

Communication Protocols

Motor Protection and Application Benefits

• Torque control softens start/stop operations to reduce water hammer in pumps and increases reliability

• Pump cleaning function reverses flow to prevent clogging

• Motor pre-heating helps remove moisture before startup

• Dynamic braking and standstill braking maintain control over load momentum

Certifications and Approvals

• Compliant with CE, UL, cULus, CCC, EAC, CQC; approvals include ABS, DNV, Lloyd’s, CCS, PRS, Class NK

• Environmental compliance: RoHS, REACH, TSCA 

Ideal Applications
Suitable for use in pump, fan, compressor, and conveyor systems. It offers an optimal balance of motor protection, energy efficiency, and system uptime, especially in water and wastewater treatment environments .
