Chassis Soft Starters

Texas Belting & Supply stocks 52 Chassis Soft Starters - reduced-voltage soft starters that ramp large motors up and down smoothly - limiting inrush current and the mechanical shock that hard across-the-line starting inflicts on pumps, compressors, and conveyors. Available, with in-stock items that typically ship same-day. Call (888) 203-2358 for sizing help.

Common Applications

• Across-the-line replacement for big motors
• Pumps and compressors with high inrush
• Conveyors and crushers needing a controlled ramp
• Limiting utility demand spikes on start

Frequently Asked Questions

Soft starter vs VFD - which do I need?

A soft starter only controls the start/stop ramp; a VFD controls speed continuously. If you don't need running speed control, a soft starter is smaller and cheaper.

How much does a soft starter cut inrush?

It reduces starting current substantially versus across-the-line, easing utility demand and mechanical stress. Sizing depends on the motor and load.

Does it need a bypass?

Many run a bypass contactor after ramp-up to eliminate heat. Enclosed packages often include it.
