When you're choosing a soft starter for a motor-control setup, the decision comes down to matching the unit to your motor and the control environment. Soft starters help reduce inrush current at startup, but only when the unit is compatible with your voltage and phase. The voltage and phase compatibility aren't just specs; they determine whether the device will even connect properly to your motor and control wiring. The wrong choice can leave you with a motor that kicks in too hard or a soft starter that simply doesn't fit the panel. Here, the choice is between a new soft starter with manual tuning controls and a used Stellar model aimed at industrial motor control. The right pick depends on whether your motor is a simple single-phase load or part of a higher-voltage industrial panel.
Quick Verdict
If you're protecting a single-phase motor, the 1/2/4/6/8KW Motor Soft Start is the practical pick, and it's also the lower-priced option. If you need a soft starter for a 480VAC 50/60Hz industrial control loop, the Stellar SR22-09 is the one to choose.

Where Each Product Wins
The 1/2/4/6/8KW Motor Soft Start wins when you want to tune the start characteristics yourself. Its potentiometer-based adjustments let you set the starting voltage and the soft-start duration, giving you direct control over how gently the motor ramps up. You can experiment with different settings and dial in the behavior you want without needing external control hardware.
The Stellar SR22-09 wins on industrial fit and motor-control design. It's built for the kind of higher-voltage control infrastructure you find in manufacturing and process settings, so it fits better when the soft starter needs to work alongside a programmable controller. Its 9 FLA rating is a clear signal that it's intended for a specific motor-load class.
Product Notes
1/2/4/6/8KW Motor Soft Start
This new single-phase soft starter puts tuning in your hands. The front-panel potentiometers adjust the starting voltage and the soft-start time, so you can tailor the ramp without relying on external control logic. What's useful is that the ramp duration can be set up to about 30 seconds at the full scale, giving you a wide window to match the motor's load. The limitation is that it's designed for single-phase AC circuits, so it won't serve a higher-voltage industrial panel. For a single-phase motor where you want to adjust the start directly, this unit gives you the control you need in a straightforward package.
Stellar SR22-09
The Stellar SR22-09 is a used soft starter with a 9 FLA rating, which makes it a strong fit for motor-control panels that depend on a PLC. The 50/60Hz rating means it can handle both supply frequencies, which is useful if your facility runs mixed-frequency equipment. The trade-off is condition: you're buying a used unit, so you accept that in exchange for the industrial feature set. If your control cabinet runs on a PLC and needs a soft starter rated for that kind of load, the SR22-09 gives you the model designation and rating to anchor the install.
Final Choice by Use Case
- For a 220V motor application, choose the 1/2/4/6/8KW Motor Soft Start.
- For an industrial motor-control panel, choose the Stellar SR22-09.
