PSE Softstarter
PSE is ABB's popular range of soft starters for general motor soft starting applications, suitable for pumps, fans, conveying and general mechanical loads. For MRO and project procurement, current rating is often more critical than simply motor kW, along with starting frequency, ambient temperature and bypass method.
The PSE part number consists of series, current specification and power/control related suffixes. The complete ordering code should be found on the nameplate or ABB ordering data. When selecting the soft starter, first determine the specifications of the soft starter according to the motor's rated current and starting conditions, and then check the main circuit voltage, control power supply, built-in bypass, communication and required protection functions.

FAQ
Frequently Asked Questions
Which specifications matter most when selecting PSE Softstarter?
Key specifications to verify are series, application. Match them against the equipment nameplate, drawing or original model, and retain every suffix, option and regional code in the complete ordering reference.
Why is the complete part number required when requesting a quote for PSE Softstarter?
Models within PSE Softstarter may differ in electrical ratings, construction, interfaces or accessories. For example, PSE85-600-70, PSE105-600-70, PSE142-600-70 are distinct configurations and cannot be interchanged on the series name alone. Using the complete part number substantially reduces mismatch risk.
How should I confirm when PSE Softstarter is used for spare parts of installed equipment?
For installed-base MRO involving PSE Softstarter, provide the original part number, nameplate photo, equipment application and quantity. We first verify the existing model and critical specifications, then check whether the original remains available. If migration is required, mounting, electrical, communication and accessory differences are compared separately.
