The Danfoss 175G5543 is a high-capacity VLT Soft Starter MCD 500 designed to provide smooth and controlled starting and stopping of large three-phase AC motors in demanding industrial applications. As part of the advanced Danfoss MCD 500 soft starter series, it delivers reliable motor control, reduced mechanical stress and comprehensive protection features for heavy-duty industrial equipment.
The MCD 500 range uses advanced digital soft start technology with current feedback and Adaptive Acceleration Control (AAC) to optimise motor ramp profiles for different applications. The integrated bypass configuration helps improve operating efficiency while maintaining reliable control during motor starting and stopping cycles.
With a rated current of 790 A, a 200–525 V AC three-phase supply and an IP00 G4 enclosure design, the Danfoss 175G5543 is suitable for large industrial motors requiring dependable soft starting performance. The unit supports 110–120 V AC and 220–240 V AC control voltage options for flexible panel integration.
Soft starters such as the Danfoss MCD 500 control the voltage supplied to AC motors during startup, reducing high inrush currents and limiting mechanical shock. This allows industrial equipment to operate more smoothly while improving motor and system reliability.
The Danfoss MCD 500 series provides intelligent motor protection, flexible configuration and advanced starting algorithms. These features make the 175G5543 suitable for large pumps, compressors, fans, conveyors and other heavy-duty industrial motor applications.
