Danfoss VLT Soft Starter MCD 500 MCD50790CT5G4X
Danfoss 175G5518 VLT Soft Starter MCD50790CT5G4X00CV1 soft starter for controlled starting and stopping of industrial three-phase motors with 790 A operational current.
Why Choose the Danfoss 175G5518 Soft Starter?
The Danfoss 175G5518 is a high-capacity VLT® Soft Starter MCD 500 designed for the intelligent starting and stopping of large three-phase induction motors in the most demanding industrial environments. Identified by the type code MCD5-0790C-T5-G4X-00-CV1, this advanced digital soft starter combines adaptive motor control, integrated bypass technology and comprehensive protection to maximise reliability, efficiency and equipment lifespan.
The MCD 500 series significantly reduces electrical inrush current and mechanical stress during motor acceleration and deceleration. Adaptive Acceleration Control automatically optimises the start and stop profile for the connected application, helping to extend the life of motors, pumps, conveyors, compressors and other driven equipment while reducing maintenance requirements.
With a 790 A rated operational current, a three-phase 200-525 V AC mains supply and a 24 V AC/DC control supply, the Danfoss 175G5518 is ideally suited to heavy industrial applications including mining, material handling, water treatment, manufacturing and process industries. The integrated bypass contactor improves efficiency by reducing heat generation and power losses once the motor reaches full operating speed.
