What Is the CAB-US515-C15-US= Power Cable?
The CAB-US515-C15-US= is a 15-amp, 125V AC power cable designed for Cisco devices operating in high-temperature environments. It features a C15 connector (IEC 60320-C15) on the device end and a NEMA 5-15P plug for U.S. outlets, engineered to safely deliver power to equipment like switches, routers, or servers where heat buildup exceeds standard thresholds.
Key Technical Specifications
- Connector Types: C15 (high-temp) to NEMA 5-15P (3-prong grounded).
- Cable Length: 1.5 meters (4.9 feet), optimized for short-reach rack installations.
- Temperature Rating: Withstands up to 120°C (248°F), compared to the 65°C limit of standard C13 cables.
- Certifications: UL/CSA listed, compliant with U.S. electrical codes.
CAB-US515-C15-US= vs. C13 Cables: Critical Differences
| Feature | CAB-US515-C15-US= | Standard C13 Power Cord |
|---|---|---|
| Heat Resistance | 120°C (C15 connector) | 65°C (C13 connector) |
| Use Case | High-power switches, PoE++ | Basic servers, low-heat gear |
| Safety Compliance | Mandatory for UL60950-1 | Sufficient for general use |
| Typical Devices | Cisco Catalyst 9500, UCS | Entry-level routers, PCs |
Why Deploy This Cable in High-Temperature Scenarios?
- Prevents Connector Melting: High-density PoE++ deployments (e.g., 90W per port) generate significant heat. Standard C13 cables degrade under prolonged exposure, risking electrical faults.
- Regulatory Compliance: Devices drawing over 10A or operating above 70°C often require C15 connectors per UL/IEC standards.
- Durability: Shielded, heavy-gauge wiring minimizes voltage drop in power-hungry setups like full-stack Catalyst chassis.

Real-World Application Insight
In data centers running Cisco’s PoE-heavy Catalyst 9300/9500 series, I’ve witnessed C13 cables warp under load, causing intermittent outages. The CAB-US515-C15-US= isn’t just a “nice-to-have”—it’s insurance against catastrophic failures in 24/7 environments. While costlier upfront, its robust design avoids costly downtime and fire risks. One overlooked detail: always pair this cable with a properly rated PDU. Even the best cord can’t compensate for undersupplied power infrastructure.
