What Is the CAB-US620P-C19-US=?
The CAB-US620P-C19-US= is a Cisco-certified 20A power cable engineered for high-density network equipment requiring IEC C19 inlets, such as enterprise switches, UPS systems, and blade servers. Designed for 120/240V AC environments, it features a NEMA L6-20P plug (US standard) and complies with rigorous safety standards to handle sustained high-current loads without degradation.
Key specifications:
- Current rating: 20A at 250V (5 kW continuous).
- Length: 2 meters (6.56 ft), optimized for vertical PDU mounting.
- Compatibility: Cisco UCS C-Series servers, Catalyst 9500 switches, and high-wattage PoE++ deployments.
Critical Design Features and Applications
- High-temperature tolerance: Insulation rated for 105°C, preventing softening or cracking in thermally dense racks.
- Locking mechanism: Optional C19 retention clips (sold separately) prevent accidental disconnects in vibration-prone environments.
- UL/CSA certification: Guarantees compliance with North American electrical safety regulations.
Why It Outperforms Generic 20A Cables
- Cisco-validated load testing: Ensures zero voltage drop under maximum load, unlike generic cables prone to resistance buildup over time.
- Shielded conductors: Minimize electromagnetic interference (EMI) in mixed AC/DC power environments.
- Precision-molded connectors: Reinforced stress relief collars reduce wear at plug-in points, extending cable lifespan by 30–50%.
Addressing Core User Concerns
Q: Can this cable replace a C15-to-L6-20P cord in existing setups?
A: No—the CAB-US620P-C19-US= is strictly for C19 inlets. Using it with C15 devices risks incompatibility due to the C19’s higher temperature rating (120°C vs. 70°C).
Q: Is it suitable for three-phase power distribution?
A: No—this cable is designed for single-phase systems only. For three-phase Cisco hardware, refer to the CAB-3PHASE-30A series.
Q: Why prioritize 2-meter length over shorter options?
A: The extra reach accommodates PDU placement at rack midpoints, reducing tension and improving airflow management in fully populated cabinets.

On-the-Ground Perspective
In high-availability environments, power cabling is the unsung hero of uptime. The CAB-US620P-C19-US= might cost 2–3× more than uncertified alternatives, but consider this: a single outage caused by a melted connector can erase years of perceived savings. For teams managing 10+ kW racks, this cable isn’t an expense—it’s insurance.
