When you're choosing between soft starters and motor controls, the first question is almost never "Which one is better?" It's "Which one actually fits the motor and the supply in front of you?" This is not a contest between two nearly identical boxes; it is a decision about which duty class matches your motor. This head-to-head lines up a single-phase module and an industrial soft starter that occupy different ends of the same product aisle.
Quick Verdict
Choose the Single Phase Motor Soft Starter for a single-phase motor where upfront cost and adjustability lead. Choose the SR22-09 Stellar Soft Starter for an industrial motor-control panel. The table below lays out the concrete price and condition differences; after that, the specs decide which one belongs in your build.
Comparison Table
| Feature | Single Phase Motor Soft Starter | SR22-09 Stellar Soft Starter |
|---|---|---|
| Price | USD 50.99 | USD 94.99 |
| Condition | New | Used |
| Supply voltage | 220V / 380V | 480V AC |
| Load spec | SSR-60WA-R1 (2KW) | 9 FLA / SR22-09 |
| Model identity | SSR-60WA-R1 | SR22-09 |
Where Each Product Wins
The Single Phase Motor Soft Starter wins on new condition, lower upfront cost, and the directness of its potentiometer-based setup. It is the lower-commitment way to add soft starting to a single-phase motor.
The SR22-09 Stellar wins on industrial fit. It is rated for a heavier motor-control duty class, and the SR22-09 model number gives you a concrete part identity to reference when working on a panel.
The module's adjustment examples are useful when you are still deciding how much starting voltage to apply. The Stellar's rated load and input voltage are the kind of specs that matter once the panel is already defined.
Single Phase Motor Soft Starter
At the lower price in this comparison, this module is the direct path to soft starting for a single-phase motor. The potentiometer adjustment lets you shape both the starting voltage and the soft-start time, with setup examples for 220V and 380V supplies. The soft-start potentiometer can extend the ramp to roughly 30 seconds on the 380V setting, so you have room to tune the start. If you are repairing or building a small single-phase motor circuit, this is a compact way to take the edge off the starting current. The trade-off is the 2KW specification, which points to lighter-duty motors. It will not cover an industrial load the way a dedicated higher-rated starter can. For a single-phase motor where price matters most, the adjustable module gives you the basics without the extra cost.
SR22-09 Stellar Soft Starter
The SR22-09 Stellar is the more specialized unit in this pairing. It is a used module from the United Kingdom, so the pre-owned condition is the first thing to weigh. Its rated load and input voltage are aligned with an industrial motor-control panel rather than a small single-phase circuit, which puts it in a heavier class. The SR22-09 model identity also makes it easy to reference a specific part when matching a panel. The limitation is that used gear comes with prior service life; you are not getting a factory-new unit. For an industrial setup that fits the SR22-09 specs, the higher price makes sense. For a light single-phase motor, it is more starter than the job needs.
Final Choice by Use Case
For a single-phase motor where the upfront cost matters most, go with the Single Phase Motor Soft Starter. For a 480VAC industrial control line with a load in the 9A range, the SR22-09 Stellar is the one to buy.
