This design guide covers the Danfoss MCD 200, MCD 201, and MCD 202 soft starter series, including overview, ratings, installation, and technical data.
The Danfoss MCD 200 Series comprises two ranges, MCD 201 and MCD 202, which share a common power and mechanical design but offer different functionality. The MCD 201 provides Timed Voltage Ramp (TVR) starting and stopping control, while the MCD 202 provides Current Limit starting control, TVR soft stop, and includes a range of motor protection functions. Both ranges include an integral bypass function to minimize heat dissipation during run.
| Mains Supply | 3 x 200 VAC ~ 440 VAC (+10% / - 15%) or 3 x 200 VAC ~ 575 VAC (+10% / - 15%) |
|---|---|
| Supply frequency | 45 Hz - 66 Hz |
| Control Supply | 24 VAC/VDC (± 20%) or 110-240 VAC (+10% / - 15%) or 380-440 VAC (+10% / - 15%) |
| Operating Temperatures | -10 °C / + 60 °C |
| Degree of protection | IP20 for MCD 200-007 to MCD 200-055; IP00 for MCD 200-075 to MCD 200-110 |
| Short Circuit Rated current | 5 kA for MCD 200-007 to MCD 200-037; 10 kA for MCD 200-045 to MCD 200-110 |
MCD 201 provides TVR starting and stopping control for use with an external motor protection device, while MCD 202 provides Current Limit starting control, TVR soft stop, and includes motor protection functions.
Yes, the integral bypass function makes the MCD 200 suitable for installation within non-ventilated enclosures without the need for an external bypass contactor.
The MCD 200 supports a start current of 400% for 6 seconds.
