Whether you’re integrating into an MCC room or packaging into an E-House, Pinnacle delivers medium-voltage switchgear solutions tailored to your application, with faster lead times, built-to-one-line precision, and comprehensive QA documentation.
What Is Medium-Voltage Switchgear — And Where Is It Used?
Medium-voltage (MV) switchgear refers to electrical switchgear assemblies rated typically between 1kV and 38kV, with 5kV and 15kV being the most common voltages used in industrial and utility-scale power systems. These systems are essential for distributing electrical power across large facilities, protecting circuits, isolating faults, and enabling safe operation and maintenance.
MV switchgear assemblies are often used in critical infrastructure such as power plants, substations, water treatment facilities, oil and gas production sites, and large manufacturing plants. They provide advanced overcurrent protection, short-circuit control, and breaker coordination to ensure uninterrupted operations.
At Pinnacle Power & Controls, we manufacture custom medium-voltage switchgear systems that comply with ANSI/IEEE C37, UL 1558, and NEC standards. Our assemblies are engineered to your one-line diagrams, bus ratings, enclosure requirements (indoor or outdoor), and application-specific needs — whether air-insulated, metal-clad, or metal-enclosed.
We support everything from standalone feeder breakers to generator tie-in panels, utility interconnects, and paralleling gear — all delivered with QA-tested reliability and engineer-backed support.
MV Switchgear Offerings & Capabilities
Medium-Voltage Switchgear Options — Built for Your Load, Site & One-Line
At Pinnacle Power & Controls, we engineer and manufacture application-specific MV switchgear systems tailored to the demands of your facility and your electrical one-line. Whether you’re feeding power to a critical substation, tying in backup generators, or distributing 15kV across a utility yard — we provide fully compliant, UL-listed switchgear with flexible configurations and installation formats.
From air-insulated switchgear (AIS) to metal-clad arc-resistant gear, our offerings span power generation, process industries, utilities, and large-scale commercial infrastructure. You’ll work directly with our engineers to define enclosure specs, interrupt ratings, bus layouts, and protection schemes — and we’ll deliver it built-to-spec, on time.
Common MV Switchgear Types We Build
Metal-Clad Medium-Voltage Switchgear
Fully compartmentalized with draw-out vacuum circuit breakers — ideal for utility interconnects and mission-critical facilities.
Feeder Breaker Lineups
Multi-bay assemblies with individually metered and protected feeder breakers — scalable for large-scale distribution.
Metal-Enclosed MV Switchgear
Compact, front-access gear for indoor or outdoor applications — fixed breakers, load interrupters, and fused switches.
Skid-Mounted MV Switchgear
Pre-mounted on steel frames with prewired components — ideal for rapid deployment and oil & gas projects.
Generator Tie-In & Paralleling Switchgear
Switchgear designed for paralleling multiple generators or integrating gensets with utility sources.
