The IE Advantage

IE’s MV custom switchgear includes both metal-clad and metal enclosed options.  We excel in design and manufacturing of specialty, custom switchgear – such as low-profile designs for mining or high amperage, 4000A designs required with short lead-times, or meeting specialty enclosure requirements.  For customers requiring custom designs, we can design in build in 12-14 weeks, the amount of time most OEMs take just to provide drawings.

We collaborate with our supply chain partners to provide UL-listed, ANSI metal-clad designs up to 25KV, and Gas Insulated Switchgear (GIS) packages up to 38KV in a compact footprint for the most demanding applications. Arc-Resistant and Arc-Mitigation designs available.
