Tradition. Technology. Innovation.
TRADITION. TECHNOLOGY. INNOVATION.
IEM began business in a barn on a family ranch in Fremont, CA. IEM grew
along with Silicon Valley, moving to a 12,000 sq ft facility in 1957, expanding
to 70,000 sq ft in 1980, 105,000 sq ft in 2003, and 130,000 sq ft in 2013.
IEM has expanded with offices in Jacksonville, FL, and Vancouver, BC.
Together, our locations represent an unparalleled solution to the most
challenging projects in the industry today.

TRADITION. TECHNOLOGY. INNOVATION.
IEM has been solving power
distribution challenges for HP,
Apple, and dozens of prominent
companies since they were startups.
IEM developed a groundbreaking
version of the medium voltage
vacuum breaker in the 1980’s,
pioneered the use of breakers on
21kV systems, and was the first
to design a 3000A free standing
breaker for utilities.
