Core features

  • Available in stand-alone or line-ups, with indoor and outdoor configurations 

  • Meets or exceeds IEEE C37.20.3 for metal-enclosed switchgear 

  • Meets or exceeds NEMA SG5 and NEMA SG6

  • Quick-make, quick-break mechanism drives switch blades at high speed into either open or closed position  

  • Switches can be supplied with manual or electrical operating mechanisms and with or without primary fuses 

  • Can eliminate the need for protective clothing around the perimeter of electrical distribution equipment

  • Door interlocks ensure that the switch and fuse panels remain closed unless the switch is opened 

  • Viewing window provides clear, visible confirmation of disconnected switch contacts 

  • Through-the-door switch operation is provided to maintain arc-resistant protection while operating the switch

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.
