ABB Soft Starters
RSP Supply carries a complete line of ABB soft starters designed to deliver smooth motor acceleration, torque control, and enhanced system reliability.
By gradually increasing voltage during startup, ABB soft starters reduce mechanical stress, inrush current, and heat generation, ensuring longer motor life and improved energy efficiency.
Ideal for heavy-duty industrial applications such as pumps, fans, and conveyors, these soft starters protect motors while optimizing performance in industries like water treatment, manufacturing, and mining. With built-in bypass functionality and intelligent control options, ABB soft starters guarantee reliable operation and reduced electrical wear across all environments.
FAQs
What does an ABB soft starter do?
An ABB soft starter gradually increases voltage to a motor, reducing inrush current, torque stress, and mechanical wear during startup.
Where are ABB soft starters used?
They’re used in pumps, fans, compressors, and conveyors in industries like water treatment, manufacturing, and mining.
How do ABB soft starters improve efficiency?

Motor Starters, Soft Starters and VFDs
Motor Starters
Motor starters safely start and stop motors in industrial applications. They include contactors, overload protection, and circuit safeguards but allow full inrush current at startup.
Pros: Lower cost, simple operation, remote control capability.
Cons: High inrush current can cause fuse or breaker trips and premature motor wear.
Soft Starters
Soft starters gently ramp up motor voltage, minimizing torque and protecting against electrical stress.
Pros: More affordable and compact than VFDs, ideal for startup control and motor protection.
Cons: Higher cost than basic starters and no continuous speed control.
VFDs
VFDs control motor speed, start, and stop by varying the frequency of supplied voltage.
Pros: Full-speed control, customizable operation, and energy savings.
Cons: Larger size, higher cost, and potential for heat generation requiring cooling systems.
