Weg SSW7000C370T411N2 SSW7000 medium voltage soft starter, 360A rated current, 4160V three-phase supply, 60Hz. NEMA 12 enclosed panel with integrated bypass vacuum contactors and closed-loop current control for controlled acceleration and deceleration of large induction motors. Includes E-Stop pushbutton, run light, fault light, and keypad for demanding industrial applications such as mining, water treatment, and heavy material handling.

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;
• User friendly configuration and operation;
• Oriented Startup function presents minimum programming sequence to commence the operation;
• SuperDrive PC software (license-free) for the Soft-Starter SSW7000 programming / operation / monitoring;
• Motor protection built-in in the standard cabinet (eliminating the need of extra protection relays);
• Ground Fault Protection - Standard;
• Input secctioning/protection integrated (line contactor or circuit breaker);
• Heavy duty design up to 50 degC ambient temperature;
• Reduction of power demand during the starting;
• Reduction of inrush current on the power supply during the starting;
• Reduction of mechanical shocks during the starting;
• Reduction of mechanical stress on the load and on the coupling;
• Increase the desing life of the motor, mechanical and electrical systems;
• Standard/customized project under customer requirements following the application characteristics.
