Medium-voltage switchgear

5-15 kV Medium-voltage metal-enclosed front accessible switchgear

Designed for applications at voltages up to 15 kV, Eaton’s MEF is the most flexible, cost-effective and space-efficient medium voltage switchgear available. Offering convenient front access to all components and connections, the metal enclosed switchgear is available in a wide variety of configurations that can be easily scaled for expansion. Its reduced footprint not only allows for space savings of more than 50%, but can be transported using a fork truck or pallet jack, eliminating the need for a crane.

VOLTAGE CLASS
up to 15 kV
CONTINUOUS CURRENT
up to 2000 A
INTERRUPT RATING
up to 40 kAIC

Core features

  • Designed for applications at voltages up to 15 kV, up to 2000A continuous current and up to 40kA short circuit withstand
  • Convenient, front accessible design enables 5/15kV switchgear to be pushed against wall
  • Available in a wide variety of configurations, standard drawing packages, integrated trips units and reduced clearance installation
  • Integrated trip unit options eliminate need for external power source/short circuit protection 
  • Maintenance-free bus connections save time and money
  • Portable design enables space savings of more than 50% and can be transported using a fork truck or pallet jack, eliminating the need for a crane 
  • Draw out compartments and arc flash modes enhance safety
  • Features insulated primary bus conductors and connections  

Easy front access to components & connections

Unlike traditional switchgear with the cable connection in the rear, the MEF’s front-accessible construction makes it easy for operators to reach all components from the front. The space-saving design can be pushed against the wall.

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.
