VLT® Soft Starter MCD 600


The VLT® Soft Starter MCD 600 combines the latest in advanced controls and protections with an increased level of intelligence for superior performance in fixed-speed applications. The MCD 600 is more flexible than ever to install, thanks to a wide variety of Ethernet and serial-based communication option cards, application-dedicated smart cards and support for eight languages. An integrated bypass ensures both extremely high efficiency and harmonic-free operation at full speed, reducing energy consumed and required cooling capacity. Ease of use is in focus with features such as the pump-clean function, PowerThrough operation, and calendar or run time-based scheduling. More extensive motor and starter protections ensure more uptime.
