Overview

The Danfoss VLT® Compact Starter MCD 201 is a panel-mount soft starter designed for 3-phase motors rated 7.5–110 kW at 400 V, with a mains voltage range of 200–575 V. This unit provides controlled voltage ramp-up during motor start to limit inrush current and mechanical stress on belts, couplings, gearboxes, and pump columns. Once the motor reaches operating speed, the built-in bypass relay connects the motor directly to the mains, minimizing losses during full-load operation. Key specifications include an 85 A current rating, 24 V AC/DC control supply (separate from the motor circuit), and frame size 2. The MCD 201 is optimized for applications requiring frequent starts, supporting up to 480 starts per hour for motors rated ≤25 A without derating. Control options include two- or three-wire operation, with programming via rotary switches and a reset pushbutton. This model (SKU 175G5204) is the soft-start variant without integrated motor protection, intended for panels where a separate overload relay is specified. The MCD 201 is physically compatible with the MCD 202 (which adds motor protection features) and shares the same compact design. Optional accessories include serial communication modules, remote operator kits, and PC software for enhanced control and monitoring.
