Danfoss VLT Soft Starter MCD 500 MCD50043BT5G1X

Why Choose the Danfoss 175G5527 Soft Starter?

The Danfoss 175G5527 is a compact VLT® Soft Starter MCD 500 designed to deliver smooth, controlled starting and stopping of three-phase induction motors in industrial machinery and automation systems. Identified by the type code MCD5-0043B-T5-G1X-20-CV2, this model features a 110-120 V AC / 220-240 V AC control supply, making it ideal for applications requiring an alternative control voltage configuration.

The MCD 500 series reduces electrical inrush current and mechanical shock during motor acceleration and deceleration, helping extend the service life of motors, pumps, compressors, conveyors and other driven equipment. Adaptive Acceleration Control automatically adjusts the motor starting profile to suit the connected application, improving system reliability while reducing maintenance requirements.

With a 43 A rated operational current, a three-phase 200-525 V AC mains supply and a 110-120 V AC or 220-240 V AC control supply, the Danfoss 175G5527 is ideally suited to industrial pumps, fans, compressors, conveyors and process machinery. Its integrated bypass contactor improves efficiency by reducing heat generation once the motor reaches full operating speed.
