Industrial Electric Mfg.
IEM is the largest independent full-line manufacturer of electrical distribution and control systems in North America. The Company has developed one of the most sophisticated electrical product manufacturing systems in the world and has cultivated partnerships with leading component suppliers resulting in optimal solutions to customer problems.
Tradition. Technology. Innovation.
For over half a century, IEM has delivered innovative electrical distribution products to meet the escalating needs of growth industries. Based in the heart of Silicon Valley, IEM has been solving power distribution challenges for Hewlett-Packard, Apple, and dozens of high tech pioneers since they were start-ups. These companies realized that IEM products were equal to any the multi-nationals could offer and that a faster, more flexible manufacturing system could provide them with the electrical equipment they needed in time to meet their demanding expansion requirements.
Beginning in a barn on a family ranch in Fremont, CA, IEM grew right along with Silicon Valley, moving to a 12,000 square foot facility in 1957, expanding to 70,000 square feet in 1980 then moving to a new state-of-the-art 105,000 square foot facility in 2003 and expanding to 135,000 square foot in 2015.
IEM engineers pioneered the development and deployment of fully integrated CAD and manufacturing systems, beginning in 1979 with the first CAD/CAM system for electrical equipment metal fabrication. The Company designed and built its own vacuum circuit breaker in 1984, pioneered the use of vacuum breakers on 21kV systems, and was the first to design a 3000 amp freestanding vacuum breaker that could be used for capacitor switching by utilities. In the late 1980’s IEM designed and built metering switchboards that were sold by one of the largest electrical manufacturers in the world. And in the early ‘90’s, the Company introduced the use of modern low voltage power circuit breakers which rendered “iron frame breakers” obsolete. IEM brought its expertise to power quality and power factor correction equipment in 1997 and has since developed unique low and medium voltage switchgear systems that have been well suited to the increased power and small footprint requirements of various industries.
Today, IEM has expanded beyond Silicon Valley to supply specialized electrical equipment throughout the U.S. and Canada. At IEM, tradition and technology still drive innovation. Products like state-of-the-art paralleling switchgear systems and fully front-accessible arc resistant switchgear are the results of this process. Responsiveness, engineering and quality remain the key to maintaining a loyal group of satisfied customers. With a significant knowledge base and experienced staff that is second to none, IEM is focused on serving the needs of these customers and continuing its role as an innovator in the electrical distribution industry.

Paralleling Switchgear
Designed and manufactured to deliver full control of custom configured power generation systems.
IEM Paralleling Switchgear and Control Systems are designed and manufactured to deliver full control of custom-configured power generation systems. They integrate all facets of metering, protection, communication and controls to deliver peak performance, system reliability and operating economy.
IEM’s experience with generators and voltage regulators from all major North American manufacturers, governor systems for prime movers, and proprietary engine controllers results in efficient and innovative parallel switchgear designs for redundant power applications.
Types of Configured Power Systems
- Prime Power – where generators are the only source or main source of power as in island-mode, marine, remote site or military type applications.
- Standby – where the generators serve as back-up to the main (utility) source, commonly installed in hospitals, airport, data centers, waste-water/water treatment facilities, including most life-safety institutional applications.
- Distributed Generation Systems – where generators are applied to supplement the main source (as in peak shave applications) and may also act as the standby system as well.
Intrinsic System Features
- Load priority control where loads are applied from a pre-determined sequence, highest to lowest priority, based on system capacity and characteristics.
- Generator operational control where only the pre-determined number of generators are asked to start and carry load, either in a scramble or preset start-sequence.
- Operator interface touch-screen terminals (OIT)/Human Machine Interface (HMI) where system controls and interrogation can be accomplished at the switchgear or from a remote network/PC/PLC.
- Remote communications in the most common industry protocols like modbus/canbus and being fully conversant with industry leading Ethernet/interface modules, comm-ports and RS 485 type connections.
- Utility paralleling system designs in passive closed transition (waiting for the sources to become synchronized in voltage, frequency and phase angle), active closed transition (where synchronization is dynamically controlled), soft load or continuous base loading systems.

Wireless Thermal Monitoring
Wireless Thermal Monitoring Solutions for Low and Medium Voltage Switchgear
- Temperature sensors installed in equipment interface with monitoring units to remotely report overheating for proactive planning and minimize downtime.
- Designed for continuous monitoring of ambient bus and power connections through measurement of wireless temperature sensors that require NO power or wiring.
- User-configurable alarms, both limit and differential via optional HMI monitoring system.
- Industry standard Modbus RTU communications to customer SCADA
Why Measure Temperature
- Bus joints and power connections are subject to overheating due to overload, corrosion, loose connections and environmental conditions
- Increase in heat will intensify until complete thermal failure of the connection or nearby insulation
- Next generation continuous Thermal Monitoring in lieu of traditional IR windows and periodic thermal imaging.
How it Works
Temperature sensors are powered by RF signals through the Thermal Monitoring Module and antenna Temperature Interface Module.
The Thermal Monitoring Module provides the measurements taken from the sensors and immediately makes available the data through industry standard communication protocols for critical equipment monitoring.
- Safety: Directly mounted wireless sensors to critical measuring points while ensuring all safety requirements are maintained.
- No Maintenance: 20+ year life expectancy
- Easy Installation: Sensors do not require “line of sight” and can be mounted under insulation boots or tape
- Reliability: Sensors designed to withstand harsh environments
