5-15 kV Medium-voltage metal-enclosed narrow design load interrupter switchgear

5-15 kV Medium-voltage metal-enclosed narrow design load interrupter switchgear

Eaton’s flexible, narrow load interrupter medium-voltage  switchgear (MVS-ND) is specially designed for smaller equipment rooms. Within a greatly reduced footprint, the switchgear incorporates front-accessible cable terminations, proven flicker blade and air chute technology, visible disconnect, and fully rated fuses. The 5-15kV switch offers the additional benefit of containing no SF6.

up to 15 kV
up to 1200 A
up to 38 kAIC

Core features

  • Reduces the width of the structure by half (to just 18 inches)

  • Uses proven flicker blade and air chute technology, while avoiding the use of SF6

  • 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 

  • 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

  • Optional integrated power switching device allows an operator to open and close the switch from a distance

Gain valueable space

The reduced footprint of Eaton’s narrow model MVS-ND delivers the same proven technology in a greatly reduced footprint. Measuring just 18 inches — half the width of traditional models — and containing no SF6, MVS-ND is the most flexible narrow load interrupter switchgear on the market.

Fully tested system configurations

The MVS-ND offers exceptional layout flexibility with a variety of options including main, tie and feeder configurations; main bus transitions from lower to upper main bus locations; and fused and non-fused switches.

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.
