UL Class 4 Fault Managed Power (FMP) cables are part of a new power distribution category introduced in the 2023 National Electrical Code (NEC) under Article 726. These cables were designed to safely deliver higher voltage and power over longer distances than traditional low-voltage systems like Class 2 or Power over Ethernet (PoE), without the risk typically associated with higher energy levels.
At Proterial Cable America, we design hybrid cable solutions that power the future of connected infrastructure. Our Power+Fiber IV cables combine high-speed fiber optic data transmission with Fault Managed Power (FMP) to deliver Class 4 DC energy—safe, scalable, and ready for tomorrow’s demands.
✅ Data + Power in One Streamlined Cable
Simplify your installs and reduce clutter by combining fiber data and DC power in one rugged, future-ready cable.
✅ 450V Class 4 FMP Technology
Our cables use NEC 2026-aligned Class 4 Fault Managed Power, delivering higher voltage with inherent safety. Unlike traditional PoE or SELV systems, these allow longer runs, higher wattage, and reduced conduit requirements.
✅ Purpose-Built for Edge Devices
From IoT sensors to access points and industrial cameras, our cables are engineered to extend performance to the outer edge of your network—without additional infrastructure.
✅ NEC 2026-Ready
PCA’s Class 4 FMP solutions comply with upcoming 2026 NEC Limited Energy guidelines for sub-600V systems, offering future-proof reliability and installation approval peace of mind.
✅ Built-In Safety
FMP systems actively monitor and shut down power within milliseconds during a fault—protecting both personnel and equipment.
✅ Digital Electricity™ (VoltServer)
FMP systems actively monitor and shut down power within milliseconds during a fault—protecting both personnel and equipment.
Proterial Cable America’s Class 4 FMP cables meets the strictest quality, safety, and performance standards, improving network reliability and ensuring seamless operation in critical environments and large-scale installations.
Our wireless cables are manufactured in state-of-the-art facilities right here in the United States, ensuring precision, quality, and dependable support for every project.
Crafted from superior materials, our wireless cable solutions provide exceptional resistance to wear, strain, and environmental challenges in both indoor and outdoor applications.
Our solutions, which incorporate hybrid cables, optical fiber, and cutting-edge innovations, are designed to meet the demands of modern wireless networks, including IoT and 5G.
Hybrid cables with Class 4 FMP integrate both power and data transmission within a single cable. They utilize Fault Managed Power systems that actively monitor and control power delivery, ensuring safety by automatically shutting down or limiting power in the event of a fault. This design allows for the safe transmission of higher voltage power (up to 450V DC) over longer distances, making them ideal for applications like smart buildings and IoT networks.
Digital Electricity™ is a technology that delivers power in discrete, controlled pulses, similar to data packets. Each pulse includes a safety check, and power is only transmitted if the system confirms the line is safe. If a fault is detected, the system halts transmission instantly. This approach enables the safe delivery of high-voltage power over long distances using standard cabling infrastructure.
Extended Reach: Capable of delivering power over distances up to 2,000 meters, surpassing traditional PoE limitations.
Higher Power Delivery: Supports power levels up to 2,000W, suitable for energy-intensive devices.
Enhanced Safety: Active monitoring ensures immediate shutdown in case of faults, protecting both equipment and personnel.
Simplified Installation: Combining power and data in one cable reduces installation complexity and cost.
Compliance with NEC Standards: Aligns with the 2023 NEC Article 726 for Class 4 circuits, ensuring regulatory compliance.
Yes, PCA Class 4 hybrid cables are designed to comply with the National Electrical Code (NEC) Article 726, which covers Class 4 Fault Managed Power systems. They are also certified under UL 1400-2, ensuring they meet stringent safety and performance standards for power and data transmission.
