Frequently Asked Questions

Does ABB sell internal soft starter spare parts (bypass contactors, gate drivers, control boards)?

ABB does not publish discrete internal spares as catalog SKUs. Internal components such as bypass contactors, gate driver boards, and control PCBs are supplied as field-replaceable kits through ABB service channels rather than off-the-shelf parts. Automation Distribution is a direct ABB account and can source these kits on request - call 1-888-600-3080 with your softstarter model number and serial.

Which AnyBus module do I need for my PSTX softstarter?

The PSTX has a built-in Modbus RTU port standard. For other industrial fieldbus protocols, an AnyBus plug-in module is required: AB-PROFINET-IO-2 for PROFINET, AB-ETHERNET-IP-2 for EtherNet/IP, AB-ETHERCAT-IP-2 for EtherCAT, AB-PROFIBUS-1 for PROFIBUS, AB-MODBUS-TCP-2 for Modbus TCP, AB-DEVICENET-1 for DeviceNet, or AB-BACNET-MSTP-1 for BACnet MS/TP. The "-1" and "-2" suffixes indicate the number of physical ports on the module.

Can I replace the cooling fan on a PSR softstarter in the field?

Yes. ABB designed the PSR fan as a field-replaceable component. The PSR-FAN3-45A covers frame sizes from PSR3 to PSR45; PSR-FAN60-105A covers PSR60 to PSR105. Replacement requires removing the unit from the panel; full instructions are in the ABB PSR manual.

What is the difference between PSTEK, PSEEK, and PSDKP-1?

PSTEK is the external remote keypad for the legacy PST softstarter series. PSEEK is the equivalent for the PSE compact softstarter series. PSDKP-1 is the modern HMI module for the PSTX series and offers a full graphic display rather than a basic keypad. Keypads are not cross-compatible between series.

Do you carry accessories for other ABB drives (ACS, ACH, DCS)?

This category covers softstarter accessories only. For accessories supporting ABB AC drives (ACS, ACH, ACQ series) or DC drives (DCS series), see the Motors & Drives section or call 1-888-600-3080. Automation Distribution can source the complete ABB Low Voltage drives line through our direct ABB account.

How do I identify the correct spare part for my softstarter?

The label on every ABB softstarter shows the catalog number (e.g., PSE142-600-70, PSTX300-600-70) and serial number. With those two values, we can match the correct AnyBus module, keypad, fan, or connection kit. Send a photo of the nameplate to Contact us or call 1-888-600-3080 and we will confirm the part on the spot.

Need an ABB soft starter spare part not listed below?

Bypass contactors, gate driver boards, replacement control PCBs, and other internal components are available through ABB service channels. As a direct ABB account, we can source these kits with your softstarter catalog number and serial. Typical sourcing time is 1 to 3 weeks.
