Medium-Voltage MCC Systems
Built for High Voltage. Engineered for High Stakes.
At Pinnacle Power & Controls, we specialize in medium-voltage Motor Control Centers (MCCs) engineered for critical infrastructure and heavy-duty motor loads. Designed for voltages from 1kV to 15kV, our MV MCCs are built to meet ANSI/IEEE C37 and UL standards, providing uncompromising safety, arc-flash protection, and long-term reliability.
Whether you’re powering turbines, compressor stations, or utility substations, our U.S.-manufactured MCC systems deliver precision motor control with options for vacuum contactors, relay protection, and SCADA integration — all optimized for rugged industrial environments and compliance with demanding codes.
Now operating as Pinnacle, we’ve enhanced our manufacturing speed, documentation process, and engineering collaboration, giving EPC contractors, OEMs, and facility teams a trusted partner for medium-voltage power systems.
What Is a Medium-Voltage Motor Control Center?
A Medium-Voltage Motor Control Center (MV MCC) is an engineered system designed to control and protect large motors operating above 1,000 volts (typically 2.3kV–15kV). These MCCs house vacuum contactors, instrument transformers, protective relays, and other switchgear-grade components — all integrated into one centralized, modular enclosure.
MV MCCs are used in power-intensive environments such as power generation, mining, heavy manufacturing, water utilities, and oil & gas, where motors exceed 200 HP and demand reliable start-up, protection, and coordination.
At Pinnacle Power & Controls, we engineer every MV MCC to meet or exceed ANSI C37, IEEE, and UL standards. Systems are fully type-tested and configured with arc-flash mitigation, relay-based protection, and optional SCADA-ready communication for remote visibility and control.
From standalone indoor systems to NEMA 3R outdoor lineups or fully enclosed E-Houses, our MV MCCs are built around your voltage requirements, motor loads, and facility standards.
Engineered Capabilities for Demanding Medium-Voltage Applications
At Pinnacle Power & Controls, every Medium-Voltage Motor Control Center (MV MCC) is engineered from the ground up to meet your specific voltage, environmental, and application demands. These aren’t off-the-shelf switchboards — they’re type-tested, UL-traceable, and built to ANSI/IEEE C37 specifications for mission-critical uptime.
Whether you’re powering 4160V pump systems in the oilfields or 13.8kV turbines at a power plant, we configure each MCC system for durability, safety, and easy field maintenance, without compromising code or delivery timelines.

Each MV MCC may be configured with:
Built for the Power Demands of High-Stakes Industries
Medium-Voltage MCCs Built for Safety, Scale & Uptime
Pinnacle Power & Controls’ medium-voltage MCCs (typically 5kV–15kV) are trusted by facility engineers, EPCs, and utilities across the U.S. for powering and protecting high-load motors in mission-critical environments. These MCCs are not only ANSI/IEEE C37 compliant — they’re built to survive harsh field conditions and rigorous QA inspections.
Each application brings different power dynamics, protection needs, and environmental stressors — that’s why our MV MCCs are tailored for each industry’s demands.
Key Sectors & Use Cases:
Built to UL, ANSI & IEEE Standards — No Compromises
Tested. Certified. Trusted in Demanding Environments.
When dealing with medium-voltage (MV) systems, compliance isn’t optional — it’s mission-critical. At Pinnacle Power & Controls, every MV MCC we manufacture is engineered by ANSI C37, UL 347, IEEE, and site-specific safety codes.
Our panels are tested in our Missouri-based facility under real-world load conditions and include the documentation needed for utility, EPC, and AHJ approvals, without delays or change orders.
Our Compliance & Safety Framework includes:
ANSI C37.20.7 & C37.20.2 Standards
Ensures safety, arc-resistance, and performance in MV switchgear and control assemblies.
NFPA 70E / NEC Article 110 & 409 Compliance
Built to minimize arc flash risk and comply with electrical workplace safety regulations.
UL 347 Certification
Verifies switchgear meets U.S. national safety codes and supports factory inspection approvals.
Custom QA & FAT Documentation
Includes load schedules, point-to-point testing, certified drawings, and thermal performance validation.
IEEE 1584-Based Arc Flash Mitigation
Incorporates bus bracing, venting, and breaker coordination for safer maintenance access.
We don’t just meet standards — we exceed them. With every MV MCC, you’re getting a code-ready system, engineered to perform under pressure and pass inspection the first time.
Frequently Asked Questions About Medium-Voltage MCCs
Any MCC rated above 1,000 volts AC is considered medium voltage. At Pinnacle, we typically build MCCs rated from 2.4kV to 15kV, designed to manage large motors in power plants, refineries, or heavy industrial environments.
Yes. We build to UL 347 standards for MV motor controllers, with testing and documentation to meet UL, ANSI C37, and IEEE requirements.
Absolutely. Our medium-voltage MCCs are custom-built to include protective relays (ANSI/IEC), SCADA I/O, Ethernet-ready devices, and smart metering panels — all pre-wired and tested.
Standard lead times are 3–6 weeks, depending on complexity. Expedited builds are available for critical-path projects.
Every project includes full electrical schematics, QA checklists, FAT reports, load schedules, point-to-point test data, and UL labeling. We also support submittals and AHJ sign-offs.
