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 in both stand-alone or line-ups.

Exceptional interrupting capabilities

The quick-make, quick-break mechanism on the medium-voltage switch provides full-load current interrupting capability, while fuses deliver accurate, permanently calibrated short circuit detecting and interrupting capabilities.

Safety is our top priority

Eaton’s medium-voltage switch includes numerous safety features, including a high-impact viewing window that allows visibility of actual blade position, door interlocks, switch interlocks, and grounded metal barrier.

Mini-MVS offers 5 kV protection in a small footprint

Seismically qualified and just 26 inches wide, Eaton’s Mini-MVS switchgear is rated 200 amperes at 5 kV, making it ideal for use in power distribution, transformer primary connections and isolation applications requiring a stand-alone assembly, cable in/cable out terminations and manual operation.

Eaton’s Electrical Engineering Services and Systems

With more than 1,500 experts in 60 locations throughout Canada and the U.S., and more around the world, Eaton’s Electrical Engineering Services and Systems team is one of the largest and most experienced service organizations in the industry.

Safeguard against switching transients

Ohmic voltage sensing (OVS) increases reliability over traditional  core and coil voltage transformers. Watch this brief video for an overview of the benefits of including an OVS system to protect against damaging transients.
