CAB-PWR-C15-ISR-A=: Why Is It Critical for Cisco ISR Routers?, Technical Advantages, and Safety Compliance

Core Design and Electrical Specifications

The ​​CAB-PWR-C15-ISR-A=​​ is a ​​high-temperature power cable​​ engineered for Cisco’s ISR 4000 series routers and similar hardware requiring robust power delivery in demanding environments. Key specifications include:

• ​​Connectors​​: ​​IEC 60320 C15​​ (device end) to ​​NEMA 5-15P​​ (standard US wall plug).
• ​​Voltage/current rating​​: 125V AC, 10A (1.25kW).
• ​​Temperature rating​​: Up to ​​120°C​​—double the tolerance of standard C13 cables.
• ​​Safety certifications​​: UL 60950-1, CSA 22.2, and RoHS compliance.

This cable is tailored for Cisco routers like ​​ISR 4451-X​​ and ​​ASR 1000 Series​​ deployed in confined spaces or high-heat environments, such as industrial control panels or outdoor enclosures.

Key Applications and Hardware Compatibility

​​Why choose CAB-PWR-C15-ISR-A= over generic power cables?​​

• ​​Heat resilience​​: Prevents connector degradation in environments with limited airflow (e.g., telecom cabinets).
• ​​Secure retention​​: The C15 connector’s notch ensures a snug fit, reducing disconnection risks from vibrations.
• ​​Compliance alignment​​: Meets Cisco’s ​​NEBS Level 3​​ requirements for carrier-grade deployments.

Common use cases include ​​SD-WAN edge nodes​​, ​​Cellular backhaul units​​, and ​​factory automation controllers​​ using Cisco ISR routers.

Addressing Critical User Questions

​​1. Can this cable replace a C13 power cord for ISR 4331 routers?​​
No. The ISR 4331 uses a C14 inlet, requiring a C13-to-C14 cable. CAB-PWR-C15-ISR-A= is designed for routers with ​​C16 inlets​​, such as ISR 4451-X.

​​2. Is it safe for outdoor use?​​
Yes, but pair with a weatherproof outlet and conduit to protect against moisture ingress.

​​3. How to verify authenticity?​​
Genuine cables feature molded ​​Cisco logos​​ and UL/CSA embossing. Trusted suppliers like itmall.sale provide batch-test reports for compliance verification.

Sourcing and Avoiding Counterfeit Risks

Non-compliant C15 cables often use lower-grade thermoplastics that soften at 90°C, risking short circuits. For mission-critical deployments, source CAB-PWR-C15-ISR-A= from authorized vendors to ensure material integrity and warranty coverage.

Field Experience: The Hidden Cost of Thermal Failure

During a railway signaling project, a team used generic C13 cables for ISR 4451-X routers in sun-exposed enclosures. Within months, heat-warped connectors caused intermittent outages, forcing a rushed retrofit with CAB-PWR-C15-ISR-A= units. The lesson? Not all power cables are equal—thermal specs aren’t just numbers; they’re the line between uptime and chaos. For high-heat scenarios, investing in purpose-built cables isn’t optional; it’s operational survival.
