Two 220V single-phase soft starters are competing for the same spot in your motor-control setup. The 1/2/4/6/8KW motor Soft Start Soft Starter is an adjustable unit that lets you shape the starting ramp, while the 220V Single Phase Motor Soft Starter Module Controller (SSR-40WA-R1) is a no-assembly module with protection-focused operation. Both are new and aimed at single-phase motors, but they solve the problem in different ways: one hands you more control, the other hands you a more self-contained package.
Quick Verdict
If you want to tune how your motor starts, choose the 1/2/4/6/8KW Soft Starter. If you want a module that installs without assembly and is built around motor protection, choose the SSR-40WA-R1.

Where Each Product Wins
The 1/2/4/6/8KW Soft Starter wins on adjustability. Its start potentiometer controls both the initial voltage and the duration of the soft-start ramp, with the maximum ramp time around 30 seconds. That gives you a level of hands-on control that can be useful when a motor needs a softer or faster entry into full speed.
The SSR-40WA-R1 wins on convenience and protection. It requires no assembly, which simplifies installation. The description also calls out protection functions that prevent motor damage and smooth starts/stops that reduce current impact and mechanical stress-helpful for pumps, fans, compressors, and conveyors.
Product Notes
#### 1/2/4/6/8KW motor Soft Start Single Phase Soft Starter AC 220V
The 1/2/4/6/8KW soft starter is the choice when you want to dial in the startup. The potentiometer adjusts the starting voltage and the ramp time, with a maximum soft-start window of about 30 seconds depending on the supply setting. That flexibility makes it a strong fit for matching a softer start to a particular single-phase motor. The limitation is the broad labeling: the title spans 1, 2, 4, 6, and 8KW, but the description points to an SSR-60WA-R unit for a 2.2kW motor. So the version you order needs to line up with the motor's power draw, rather than assuming one listing covers every size in the title.
#### 220V Single Phase Motor Soft Starter Module Controller (SSR-40WA-R1)
The SSR-40WA-R1 is the more turnkey option. With no assembly required, installation is mostly about connecting the module into the motor circuit. The description emphasizes protection functions that help prevent motor damage and smooth start/stop behavior that cuts current impact and mechanical stress. It is described for equipment such as pump stations, fans, compressors, conveyors, and similar systems, which makes it easy to see where it belongs. The limitation is its focused scope: it is a 220V single-phase module with a 2, 4, 6, or 8KW range, so it is not positioned as a universal soft starter but as a targeted solution for that motor class.
Final Choice by Use Case
Choose the 1/2/4/6/8KW soft starter if you value adjustable starting behavior and a wider single-phase power range. Choose the SSR-40WA-R1 if you prefer a no-assembly module with protection features and a clear fit for 2-8KW, 220V, single-phase motor loads.
