Defining the CAB-I309-C19-IND=

The ​​CAB-I309-C19-IND=​​ is a Cisco-certified, industrial-grade power cable designed to connect high-wattage networking equipment to three-phase power sources. Built for demanding environments, it features a ​​C19-to-C20 connector configuration​​, enabling safe power delivery to Cisco switches, routers, and UPS systems operating in harsh conditions. Its ruggedized construction addresses challenges like temperature extremes, moisture, and mechanical stress.

Key Technical Specifications

• ​​Connector Type​​: C19 (IEC 60320 standard) on one end, C20 inlet on the other.
• ​​Current Rating​​: ​​16A continuous​​, with surge tolerance up to 20A.
• ​​Voltage​​: Rated for ​​250V AC​​, compatible with three-phase industrial power grids.
• ​​Cable Length​​: 3 meters (standard), with reinforced shielding for EMI resistance.
• ​​Certifications​​: UL 62368-1, CE, and RoHS compliant.

​​Why C19/C20 connectors?​​ These heavy-duty connectors are standard in high-power data center and industrial gear, ensuring secure, vibration-resistant connections.

Primary Applications

1. ​​Industrial Switch Power Supply​​: Connects Cisco Catalyst IE3400/IE3300 series switches to three-phase power distribution units (PDUs).
2. ​​Data Center UPS Integration​​: Links Cisco UPS systems (e.g., SRT series) to backup power sources.
3. ​​Outdoor Telecom Cabinets​​: Resists UV degradation and corrosion in cellular tower installations.

Addressing User Concerns

​​Q: Can this cable support PoE++ (90W) devices?​​
Yes, but only as part of a broader power chain. The CAB-I309-C19-IND= delivers power to the device itself, not via Ethernet.

​​Q: Is it compatible with non-Cisco PDUs?​​
Physically yes, but Cisco recommends using certified components to maintain warranty and safety compliance.

​​Q: How does it differ from standard C19 cables?​​
The ​​industrial-grade PVC jacket​​ and ​​triple-layered shielding​​ provide superior protection against abrasion, oil, and electromagnetic interference compared to generic cables.

Field-Tested Perspective

In refinery and mining deployments where equipment failure isn’t an option, the CAB-I309-C19-IND= has proven its resilience. While its price point is higher than off-the-shelf alternatives, the cost of replacing a melted cable or troubleshooting power instability in a remote site dwarfs the initial investment. Always pair this cable with appropriately rated circuit breakers and PDUs to avoid overcurrent risks. If your environment includes frequent electrical noise (e.g., near heavy machinery), this cable’s shielding is non-negotiable.
