WEG SSW7000C100T411N2 is a medium voltage soft starter from the SSW7000 series, rated for 750 HP at 4160V three-phase 60 Hz operation. This reduced voltage starter features closed-loop current control and integrated bypass vacuum contactors for smooth acceleration of large induction motors. It is designed for demanding applications such as pumps, compressors, and conveyors, providing motor protection and reducing mechanical stress during start-up.

The soft-starters SSW7000 operates on the acceleration/deceleration and on the protection of medium voltage three-phase induction motors. This Soft-Starter is available on 2,3 kV up to 13,8 kV voltage range, attending applications that requires 300 HP up to 16300 HP power range.

Developed to ensure excellent performance, the SSW7000 application minimize the current surges on the motor starting, prevents mechanical shocks on the load and on the motor, eliminate the water hammer during the pump stopping, and protects the electrical motor. Consequently it helps on the money saving, reducing significatly the expenses of maintenance of bearings, couplings, gear boxes, pulleys, belts and chains, electrical circuits, an so on.

Hence the SSW7000 is the complete prepackaged and engineered solution within security and reliability for several applications and for diversificated industrial segments.

• 6 modes of smooth starting/stopping preprogrammed, considering the technology of the TFTC - "Totally Flexible Torque Control" developed by WEG (which uses the vector control and control of direct torque concepts, based on technologies developed and applied for the vector frequency inverters) providing  a linear speed ramp according to the load type applied to the motor;
