Choosing among VFDs soft starters motor controls starts with one important distinction: a soft starter is for the motor's startup behavior, while a variable-frequency drive is a different type of control. Here, the main split is between three listed single-phase modules and the AceCrew AC-310, a stated 200V-240VAC three-phase controller. Match the electrical format and stated power label first, then use condition and listed price to narrow the choice.
Quick take
- Choose the AceCrew AC-310 for a stated 200V-240VAC, 60Hz, three-phase motor application in the listed 1HP-20HP range, especially where programmable soft-start control matters.
- Choose the Yuesheng SSR-100WA-R2 when a single-phase 4KW motor soft starter module is the target.
- Choose the SSR-60WA-R1 (2KW) specification in the Single Phase Motor Soft Starter when a stated 2KW single-phase module is the closer match.
- Choose the 220V Single-Phase Motor Soft Starter Module Controller when the lowest listed price and a single-phase starter-module title are the priority.
- Do not treat the AceCrew AC-310 as a VFD: it is expressly described as unable to change a motor's running speed or direction.
Listed-price comparison
| Motor soft starter | Listed price | Price bar | At-a-glance distinction |
|---|---|---|---|
| AceCrew AC-310 1HP-20HP | USD 399.99 | 200V-240VAC three-phase controller | |
| 220V Single-Phase Motor Soft Starter Module Controller | USD 47.99 | Lowest listed price; single-phase title | |
| Single Phase Motor Soft Starter, SSR-60WA-R1 | USD 56.99 | Stated 2KW specification | |
| Yuesheng SSR-100WA-R2 | USD 75.00 | Stated 4KW single-phase module |
Decision matrix
Electrical format: The AceCrew AC-310 is the only entry identified as a 200V-240VAC, 60Hz, three-phase controller. The other three titles identify single-phase motor soft starter modules.
Stated capacity: The Yuesheng title carries a 4KW label, while the Single Phase Motor Soft Starter lists specification SSR-60WA-R1 (2KW). The AceCrew AC-310 is labeled for 1HP-20HP.
Condition: Yuesheng SSR-100WA-R2 is listed as New - Open box. The AceCrew unit and both generic single-phase modules are listed as New.
Control goal: For adjustable motor running speed or direction, the AC-310 is not appropriate because its description specifically says it is not a VFD. Its role is soft starting rather than variable-frequency speed control.
Product notes
NEW AceCrew 1HP-20HP Motor Soft Starter 200V-240VAC 3-Phase Controller AC-310
For a stated 200V-240VAC, 60Hz, three-phase motor setup, the AceCrew AC-310 is the distinctly targeted choice. Its 1HP-20HP title range and 20HP rated-load attribute make it the broadest motor-power entry here. The description also calls out programmable adjustment, plus independent motor on/off control by button or switch. Choose the AC-310 when those three-phase and horsepower details describe the intended motor-control project. The key limitation is equally explicit: AC-310 is not a VFD, so it cannot alter motor running speed or direction. Its listed price is also the highest of the four.
220V Single-Phase Motor Soft Starter Module Controller 2-8KW Online
The 220V Single-Phase Motor Soft Starter Module Controller is the entry to consider when the lowest listed price is the deciding factor and a single-phase starter module is wanted. Its description identifies both a start potentiometer and a soft-start potentiometer, giving the module adjustable startup settings. The new condition is another straightforward fit for shoppers focused on a new component. Its concrete constraint is electrical format: the title specifies a 220V single-phase motor soft starter module, so it does not match the three-phase format stated for the AceCrew AC-310. Keep the decision centered on the single-phase requirement named in its title.
Single Phase Motor Soft Starter Single-phase Soft Starting Module Soft Start
The Single Phase Motor Soft Starter carries the specific SSR-60WA-R1 (2KW) designation, making it the clearest pick for a request built around that 2KW specification. It is listed as new, and the description identifies start and soft-start potentiometers for adjustment. The stated 550g weight may also help distinguish the module when comparing the exact SSR-60WA-R1 designation. Choose it when a single-phase soft-start module with the named 2KW specification is the intended match. The limitation is its stated 2KW specification: it is not the 4KW module named in the Yuesheng SSR-100WA-R2 title.
Yuesheng SSR-100WA-R2 Single-Phase Intelligent Motor Soft Starter Module 4KW
Yuesheng SSR-100WA-R2 stands out for shoppers seeking the stated 4KW single-phase intelligent motor soft starter module. The model number is clearly named in both the title and model attribute, which is useful when the project calls for SSR-100WA-R2 specifically rather than a generic module name. Choose this module when the 4KW label is the deciding capacity target and a single-phase configuration is required. Its listed price sits between the generic single-phase modules and the AceCrew controller. The important tradeoff is condition: the SSR-100WA-R2 is listed as New - Open box, unlike the other three entries, which are listed as New.
Final recommendation by use case
Pick the AceCrew AC-310 for the stated 200V-240VAC three-phase and 1HP-20HP application, provided soft starting-not speed or direction control-is the goal. Pick the Yuesheng SSR-100WA-R2 for a specifically named 4KW single-phase module. Pick the Single Phase Motor Soft Starter SSR-60WA-R1 when its 2KW specification is the closer fit. Pick the 220V Single-Phase Motor Soft Starter Module Controller when the lowest listed price leads the decision. For a requirement centered on changing motor speed or direction, set aside the AC-310 and look for a variable-frequency drive rather than a soft starter.
