About the PSTX370-600-70
About the PSTX370-600-70
The ABB PSTX370-600-70 soft starter (SKU: 1SFA898115R7000) is a 370 A, 208–600 V AC three-phase electronic soft starter from the ABB PSTX series, designed to deliver smooth, controlled motor starting and stopping for up to 200 kW loads. With a wide control voltage range of 110–250 V and compact dimensions, the PSTX370-600-70 reduces mechanical stress, inrush current, and energy consumption during motor start-up, making it a high-performance solution for demanding motor control applications.
Certifications & Standards
- IEC 60529: Degrees of protection provided by enclosures (IP Code)
- IEC 60547-1: Semiconductor devices — soft starters standard compliance
- EN 60529: European harmonised standard for enclosure protection ratings
- CSA: Canadian Standards Association certification for North American markets
- REACH: EU regulation on chemical substances — compliant
- RoHS: Restriction of Hazardous Substances Directive — compliant
- WEEE: Waste Electrical and Electronic Equipment Directive — compliant
- CCC: China Compulsory Certification for the Chinese market
- CE: European Conformity marking — meets EU safety and performance requirements
Applications & Use Cases
The ABB PSTX370-600-70 soft starter is engineered for a wide range of industrial motor control scenarios where direct-on-line starting would cause excessive mechanical or electrical stress. Typical applications include pumps, fans, compressors, conveyors, and mixers. By controlling the ramp-up torque and reducing starting current, the PSTX370-600-70 extends motor and driven-equipment service life, lowers peak demand charges, and minimises voltage dip on the supply network. The unit suits installation in motor control centres (MCCs), standalone panels, and process automation systems across industries such as water treatment, HVAC, oil & gas, mining, and manufacturing.
