ABB PST Series Standard Soft Starter, 3-phase Motor Controller for Pumping Station, Fan & Compressor Protection
ABB PST Series Standard Soft Starter
ABB PST Series Standard Soft Starter, 3-phase Motor Controller for Pumping Station, Fan & Compressor Protection.
ABB PST is a general-purpose industrial low voltage soft starter balancing performance and cost, a top-selling model
for overseas municipal and water projects. It supports dual start modes: current limit and voltage ramp, precisely
controlling motor starting current and torque to solve pump water hammer, fan startup vibration and grid surge problems.
Equipped with local operation panel and built-in bypass contactor, it provides comprehensive protection, stable durability
and wide power coverage. It fits most medium & large general industrial loads, with huge demand for existing equipment replacement.
Key Features
- Dual-mode intelligent start-stop: Voltage ramp + current limit start for various standard industrial loads
- Comprehensive motor protection: Overload, phase loss, phase sequence, current unbalance & overheat multi-protection
- Built-in bypass operation: Auto bypass switch reduces heat loss, suitable for 24h continuous operation
- Visual panel commissioning: Real-time operation data display, self-diagnosis fault for efficient field maintenance
- Full range high power specifications: Covers medium & large pumping stations and fan equipment
- High compatibility for replacement: Suitable for upgrade & renovation of old ABB equipment, high overseas maintenance inquiry volume

Frequently Asked Questions
Q1: What is the core difference between PST and PSE series?
A: PST is standard industrial version with higher power rating and complete protection, supporting dual start modes for medium & large loads. PSE is compact economical version only for low-power light loads.
Q2: What are the benefits of built-in bypass function?
A: When motor runs normally, thyristor is bypassed with zero heat and low loss, ideal for 24/7 continuous pumping station operation.
Q3: Does PST support remote monitoring?
A: Optional dedicated communication module to read remote data and monitor faults for automation projects.
Q4: How to eliminate pump water hammer via soft starter?
A: Extend soft start and soft stop ramp time to slowly adjust motor speed, buffer pipeline pressure and prevent water hammer damage.
Q5: Can old ABB soft starters be replaced directly by PST?
A: High compatibility for same current rating with minimal rewiring. Preferred choice for overseas equipment renovation.
Q6: Can PST work under long-term continuous working conditions?
A: Fully applicable. It is standard equipment for continuous operation in overseas municipal water and pumping station projects with proven stability.
