The Danfoss VLT® Soft Start Controller MCD 100 (SKU: 175G4005) is a compact, fixed-configuration soft starter designed for small motors up to 10 HP (7.5 kW) with a current rating of 15 A. It operates on a wide mains voltage range of 380-480 V, eliminating the need for voltage-specific variants. This cost-effective alternative to traditional contactors or star/delta starters reduces mechanical stress and electrical surges during motor startup, extending equipment lifespan. Key features include adjustable ramp time, starting torque, and kick start via front-panel controls. The MCD 100 supports up to 480 starts per hour without derating, making it ideal for applications requiring frequent motor cycling. Its DIN rail mount design (IP20 enclosure) ensures easy installation in control panels. The built-in bypass relay minimizes operational losses under full load after startup. Applications include pumps, fans, conveyors, and other small industrial machinery where controlled acceleration is critical. The unit is factory-configured for immediate use, with the type code MCD100-007,480V/softstart 380-480V,7,5kW identifying this exact build. Control voltage is flexible at 24-480 V AC or DC, and the power range spans 0.1-11 kW (up to 25 A).

How to Install the Danfoss MCD100 Soft Starter

Step-by-step guide to mounting and wiring the MCD100 soft starter on a DIN rail.

Estimated time: 20m

Tools needed:

Screwdriver, Wire strippers, Multimeter

Supplies needed:

DIN rail, Mounting screws, Electrical wiring (per local codes)

  1. Mount the soft starter on the DIN rail

    Position the MCD100 on the DIN rail in the control panel. Ensure it is securely latched in place.

  2. Connect the power supply

    Wire the mains power (380-480 V AC) to the input terminals (L1, L2, L3) as per the wiring diagram. Verify voltage with a multimeter before energizing.

  3. Connect the motor

    Wire the motor to the output terminals (T1, T2, T3) of the soft starter. Ensure proper phase sequence and tighten all connections.

  4. Connect the control voltage

    Apply the control voltage (24-480 V AC/DC) to the control terminals as specified in the manual. Verify control voltage is within range.

  5. Configure startup parameters

    Adjust the ramp time, starting torque, and kick start settings using the front-panel controls. Refer to the manual for recommended settings based on your application.
