Danfoss 175G5589 VLT Soft Starter MCD 500 with 790 A current rating and three-phase 380-690 V AC operation for heavy industrial motor control applications.
The Danfoss 175G5589 is a high-performance VLT® Soft Starter MCD 500 designed for controlled starting and stopping of large three-phase motors in demanding industrial applications. As part of the Danfoss MCD 500 soft starter range, it provides advanced motor control, intelligent protection features and reliable performance for heavy-duty automation and process systems.
This digital soft starter provides a complete motor starting solution using current transformers, motor current feedback and Adaptive Acceleration Control (AAC) technology. These advanced functions help optimise motor ramp profiles, reduce mechanical stress and improve the operational reliability of connected equipment.
With a rated current of 790 A and support for three-phase 380–690 V AC supplies, the Danfoss 175G5589 is suitable for large industrial motors used in pumps, compressors, fans, conveyors and heavy processing machinery. Its G4 frame design and IP00 enclosure make it suitable for integration into customised electrical control panels.
Soft starters such as the Danfoss VLT® MCD 500 regulate motor acceleration and deceleration by controlling voltage during startup and shutdown. This reduces mechanical shock, limits current surges and helps extend the service life of motors and connected machinery.
The MCD 500 series is designed for industrial environments requiring dependable motor management, flexible configuration and advanced protection. The Danfoss 175G5589 delivers reliable control for large motors in modern automation, manufacturing and process applications.
