WEG SSW07 series soft starters are a versatile and reliable solution for starting and stopping three-phase induction motors. The SSW07 is compact optimizing space in electric panels. It already incorporates electric motor protection. It adapts to customer needs through its easy-to-install optional accessories.
Features
- Significant reduction in mechanical stresses of the coupling and transmission devices (gearboxes, pulleys, gears, conveyors, etc.) during start
- Increases motor and equipment lifetime due to the elimination of mechanical shock
- Easy operation, setup, maintenance & installation
- Operates in environments up to 55ºC (without derate for all models)
- Integral, electronic motor protection
- Built-in electronic thermal relay
- Avoids the “Water Hammer” in pumps
- Limitation of voltage drop during start
- Universal voltage (220 to 575 Vac)
- Switched type power supply with EMC filter for the control electronics (110 to 240 Vac)
- Thermal monitoring of both motor and soft starter

Operating interface (HMI)
7-segment LED display, providing excellent visibility of the parameters. It also incorporates the copy function, which allows you to copy the parameter setting from one SSW07 to another, providing programming agility, reliability and repeatability in the manufacturing process of serial machines.
Network Communication
Especially designed to integrate large industrial automation plants, the Fieldbus communication networks provide advantages in the complete, on-line supervision, monitoring and control of the SSW07, producing high performance and great operational flexibility, characteristic required by applications on complex and/or integrated systems.
Applications
The three-phase voltage control on the SSW07 allows its use in applications considered heavy, such as alternate, centrifugal pumps (sanitation, irrigation and oil), fans, exhausters, blowers, air compressors, refrigeration (screw and piston), mixers, aerators, centrifuges, rock crushers, grinders, woodchippers, paper refiners, rotary ovens, wood saws and planes, ball and hammer mills and load conveyors.
