Danfoss VLT Soft Starter MCD 500 MCD50428CT5G4X
Danfoss 175G5515 VLT Soft Starter MCD50564CT5G4X00CV1 soft starter for controlled starting and stopping of industrial three-phase motors with 564 A operational current.
Why Choose the Danfoss 175G5515 Soft Starter?
The Danfoss 175G5515 is a heavy-duty VLT® Soft Starter MCD 500 engineered for the controlled starting and stopping of large three-phase induction motors in demanding industrial environments. With the type code MCD5-0428C-T5-G4X-00-CV1, this intelligent digital soft starter combines adaptive motor control, integrated bypass technology and comprehensive protection to maximise equipment reliability and operational efficiency.
Designed for high-power industrial applications, the MCD 500 series reduces electrical inrush current and mechanical shock during motor acceleration and deceleration. Adaptive Acceleration Control automatically optimises the start and stop profile to suit the connected load, helping to extend the service life of motors, gearboxes, conveyors, pumps and other driven equipment while reducing maintenance costs.
With a 428 A rated operational current, a three-phase 200-525 V AC mains supply and a 24 V AC/DC control supply, the Danfoss 175G5515 is ideally suited to large pumps, compressors, crushers, conveyors, fans and heavy process machinery. The integrated bypass contactor improves efficiency by reducing heat generation and power losses once the motor reaches full operating speed.
