IEM Difference

Fully rated bus is based on density ratings, not UL heat rise tests, resulting in more bus and lower operating temperatures.

All enclosures are designed for specific application with improved dimensional flexibility and finished using state of the art powder coating system providing an indoor finish that exceeds the 1500 hour salt spray testing requirement for outdoor equipment by over 3000 hours.

Component and metering selections are based on value engineering for the application and optimized to meet specifications.

Technical Specifications
  • IEM Switchgear meets seismic testing, circuit requirements as outlined by IEEE344 and ICC-ES-AC156.
