1SFA898111R7000 PSTX170-600-70 is an ABB softstarter used with the documented ABB Drives platform. Selection must match the complete product identity, hardware execution, connected assemblies and approved system configuration.
Before replacing 1SFA898111R7000 PSTX170-600-70, compare the supplied nameplate, revision, connectors or terminals and installed position with the original equipment record. After installation, review diagnostics and complete the approved functional checks before service.
ABB 1SFA898111R7000 PSTX170-600-70 documentation and reference links.
Important Notice: Every linked document must identify the listed model or its documented family. Confirm the complete order code, hardware revision and installed-system requirements before replacement.
Select the 171 A unit from the actual motor current, starting duty, starts per hour and ambient derating.
Back up ramp, current-limit, kick-start, protection and fieldbus settings before replacement.
Prove phase order, soft start, bypass transition, stop behavior and protection trips before automatic operation.
ABB maps article 1SFA898111R7000 to PSTX170-600-70 with 171 A operational current. The 600 designation identifies the applicable main-circuit voltage class; motor power is application- and voltage-dependent, so current and start duty remain the primary selection checks.
PSTX combines controlled starting with an integrated bypass path and configurable motor protection. After restoring settings, observe current balance and acceleration, confirm bypass engagement, and prove each enabled protection without transferring parameters from a different PSTX size.
