Medium-Voltage Switchgear Systems by IEP
5kV–15kV MV Switchgear | UL 1558 / UL 891 | ANSI/IEEE C37 Compliant
At IEP, we develop purpose-built medium-voltage (MV) switchgear solutions engineered to meet the real-world demands of industrial infrastructure, utilities, and mission-critical facilities. With voltage classes ranging from 400A to 5,000A, our assemblies are crafted for performance, protection, and seamless integration into new or existing electrical systems.
We specialize in delivering customized power distribution systems built around your site specifications, one-line diagrams, protection requirements, and coordination schemes. Whether you’re interconnecting with a utility, managing multiple generators, or operating complex industrial loads, our MV switchgear ensures safe operation, rapid fault response, and system reliability.
What Is Medium-Voltage Switchgear?
Medium-voltage switchgear encompasses power distribution equipment operating between 1kV and 38kV, typically applied in 5kV and 15kV systems. MV switchgear houses protective devices, vacuum circuit breakers, bus bars, and relays that facilitate:
These systems are indispensable in facilities where power reliability and fault containment are mission-critical.
- Load isolation for maintenance
- Overcurrent and short-circuit protection
- Equipment coordination and system segmentation
- Voltage regulation and backup power routing
