The WEG Electric Soft Starts SSW07 Series offers several advantages that make it a preferred choice for controlling and protecting three-phase induction motors:

Smooth Acceleration and Deceleration:
The SSW07 series uses thyristor control to adjust the voltage applied to the motor, allowing for smooth starting and stopping. By mitigating the mechanical shock associated with direct-on-line starting, not only does the motor life extend, but also the life of the driven equipment like gears, belts, and bearings. This reduces mechanical stress on the motor and connected machinery, extending their lifespan and reducing maintenance costs. The smooth starting and stopping also contribute to lower noise levels during motor operation, which is beneficial in noise-sensitive environments.

High Performance with Cost Efficiency:
Designed with DSP (Digital Signal Processor) control, the SSW07 provides high performance during motor starts and stops with a favorable cost-benefit ratio. This makes it an economical choice for applications where performance is critical without compromising on cost.

Ease of Setup and Operation:
The soft starter is noted for being easy to set up, which simplifies both the initial installation and daily operations. This feature is particularly beneficial in environments where rapid integration and minimal downtime are priorities.

Compact Design:
The SSW07 is designed to be compact, optimizing the use of space within electrical panels. This compactness is advantageous for installations where space is at a premium or for retrofitting existing systems.

Integrated Motor Protection:
It incorporates comprehensive electrical motor protection, which helps in safeguarding the motor against overloads, underloads, phase loss, among other fault conditions, thereby enhancing system reliability.

Adaptability with Optional Accessories:
The SSW07 can be enhanced with optional accessories like keypads for easier local control, communication interfaces for integration into broader control systems, or motor PTC inputs for additional thermal protection. This adaptability allows for customization to meet specific application needs.

Energy Efficiency:
Although not explicitly mentioned in the web results, the smooth control of motor speed during start-up can lead to energy savings by reducing inrush current and mechanical wear, which aligns with broader industry trends towards energy efficiency. The energy efficiency aspect not only reduces operational costs but also contributes to a lower carbon footprint, aligning with more stringent environmental regulations and corporate sustainability goals.

These features collectively make the WEG SSW07 Soft Start Series suitable for a wide range of industrial applications, from pumps and fans to heavy machinery in sectors like mining, cement, and pulp and paper, where motor control and protection are crucial.
