Danfoss MCD200 Soft Starters — Compact Solutions for Basic and Medium Duties

The Danfoss VLT® Soft Starter MCD 200 series comprises two distinct product lines: the basic MCD 201 (voltage ramp-up/ramp-down only) and the advanced MCD 202 (which includes integrated electronic motor protection and current limit control). Designed with a bookstyle compact frame and on-board bypass contactors across the entire 7.5 to 110 kW power range, the MCD 200 range is ideal for installation in space-restricted control panels without requiring large external heatsinks.

Typical Applications for Danfoss MCD200

• Submersible and Borehole Pumps: The MCD 201 provides a controlled deceleration ramp using Timed Voltage Ramp (TVR) to prevent water hammer.
• Centrifugal Exhaust Fans: Optimizes the starting ramp for high-inertia fan impellers, reducing stress on belts and couplings.
• Agitators and Conveyors: Soft starting eliminates startup mechanical jerks, extending gear and bearing operational life.

What Differentiates Danfoss MCD200 from Competitors

A key marketing and engineering benefit of the MCD 200 is the budget flexibility of selecting the basic starter (MCD 201) or upgrading to the fully protected version (MCD 202) depending on project demands.

When Danfoss MCD200 is NOT Suitable

• For highly demanding heavy-duty industrial tasks where fully symmetrical three-phase thyristor control is required — select the Danfoss MCD 500.
• In water systems requiring active Torque Control to prevent severe hydraulic shocks — choose the ABB PSE.

Our Panel Installation Recommendations

The MCD 200 range is a highly reliable B2B workhorse. When designing system schematics, remember that the MCD 201 series lacks integrated thermal protection; you must install an external thermal overload relay (e.g., GV2/GV3 type) to protect the windings. Mounting is straightforward, with DIN-rail compatibility on smaller frames.
