Danfoss 175G5548 VLT Soft Starter MCD 500 with 21 A current rating, integrated bypass and three-phase 380-690 V AC operation for industrial motor control applications.
The Danfoss 175G5548 is a compact and reliable VLT Soft Starter MCD 500 designed to provide smooth acceleration and controlled stopping of three-phase AC motors in industrial applications. As part of the proven Danfoss MCD 500 soft starter series, it provides intelligent motor starting, reduced mechanical stress and dependable motor protection for industrial automation systems.
The MCD 500 range uses advanced digital soft start technology with current feedback and Adaptive Acceleration Control (AAC) to automatically optimise motor starting and stopping profiles. This helps reduce electrical stress, minimise mechanical shock and improve equipment reliability across a wide range of industrial applications.
With a rated current of 21 A, a 380–690 V AC three-phase supply and an IP20 G1 enclosure design, the Danfoss 175G5548 is suitable for smaller industrial motors requiring controlled starting performance. The unit includes an integrated bypass contactor and supports 24 V AC/V DC control voltage for flexible machine integration.
Soft starters such as the Danfoss MCD 500 control motor voltage during startup, reducing high inrush currents and limiting mechanical stress on connected equipment. This allows motors to accelerate smoothly while improving system reliability and reducing maintenance requirements.
The Danfoss MCD 500 series provides advanced motor protection, flexible programming and intelligent starting algorithms. These features make the 175G5548 suitable for pumps, fans, conveyors, compressors and general industrial machinery requiring dependable motor control.
