Overview

The Danfoss VLT® Soft Start Controller MCD 100 (SKU: 175G4002) is a compact, fixed-configuration soft starter designed for small motors up to 2 HP (1.5 kW). It operates on a 400–480 V mains supply, eliminating the need for voltage-specific variants. This unit limits starting torque and inrush current, making it ideal for straightforward applications like pumps, fans, and conveyors. Key specifications include a control voltage range of 24–480 V AC/DC and a power rating of 0.1–11 kW (up to 25 A). The MCD 100 features adjustable ramp time, starting torque, and kick start via front-panel controls. It supports up to 480 starts per hour without derating, ensuring reliable operation in demanding environments. The IP20-rated enclosure is DIN rail mountable, offering a space-saving, "fit and forget" solution. Sold as a named rating (MCD 100-001, 480V/soft start 400–480V, 1.5 kW), this unit is pre-configured for immediate deployment. It replaces traditional contactors and star/delta combinations, reducing installation complexity and costs. Compatible with grounded delta power systems, the MCD 100 is a cost-effective alternative for OEMs and system integrators seeking a simple, durable soft starter.
