Description
About the PSTX37-600-70
About the PSTX37-600-70
The ABB PSTX37-600-70 (SKU: 1SFA898104R7000) is a 37 A three-phase soft starter from the ABB PSTX series, rated for 208–600 V AC supply voltage and delivering up to 18.5 kW motor power control. Designed for demanding industrial motor control applications, the PSTX37-600-70 provides smooth motor starting and stopping, reducing mechanical stress and inrush current in automation and process control systems. With a control voltage range of 110–250 V and a compact footprint of 200 × 282 × 388 mm, it integrates cleanly into standard control panels and motor control centres.
Certifications & Standards
- CE: Compliant with applicable European Union directives for electrical equipment
- CCC: China Compulsory Certification for the Chinese market
- DNV: Det Norske Veritas approval for marine and offshore applications
- IEC 60947-1: Low-voltage switchgear and controlgear — general rules
- CSA: Canadian Standards Association certification for North American markets
- REACH: Compliant with EU REACH regulation on chemical substances
- RoHS: Restriction of Hazardous Substances compliant
- WEEE: Waste Electrical and Electronic Equipment directive compliant
Applications & Use Cases
The ABB PSTX37-600-70 soft starter is suited for a wide range of three-phase motor-driven applications where controlled acceleration and deceleration are critical. Typical applications include pumps, fans, compressors, conveyors, and mixers found in water treatment, HVAC, marine, oil & gas, and general industrial automation environments. The DNV certification makes the PSTX37-600-70 particularly well-suited for shipboard and offshore motor control duties, while CSA certification opens deployment across North American installations. Its wide supply voltage range (208–600 V AC) and broad control voltage window (110–250 V) give engineers and panel builders maximum flexibility across global projects.
