Core features

Powerful, rugged arc protection

Eaton’s MVS medium-voltage switch provides everything you need for safe, reliable switching and fault protection in an arc-resistant design. Packed with integral safety features, the vertical structure is built to withstand the effects of internal faults up to the maximum current rating, with a welded, heavy-duty door design that contains arcing faults.

Easy accessibility

With an IEEE C37.20.7 type 2B accessibility rating, the Eaton MVS provides arc-resistant features and protection at the freely accessible exterior (front, back and sides) of the equipment as well as in front of the instrument/control compartment, with the door opened, while the equipment is energised and operating normally.

Powerful switch protection

With the ability to manually cut off the power supply to a certain area or equipment, MVS switches are ideal for applications such as transformer primaries, duplex switches and selector switches. They are available as both a stand-alone or in line-ups.
