Cisco CAB-3P-JPN=: How Does This 3-Prong Power Cable Ensure Compliance and Safety for Japanese Network Deployments?

​​What Is the Cisco CAB-3P-JPN=?​​

The ​​Cisco CAB-3P-JPN=​​ is a ​​3-prong AC power cable​​ designed for Cisco networking equipment deployed in Japan. As specified on Cisco.com, this cable complies with Japan’s ​​Electrical Appliance and Material Safety Law (PSE)​​ and provides a secure connection between devices like Catalyst switches, routers, or chassis and local power outlets.

​​Key Technical Specifications​​

• ​​Plug Type​​: ​​Type B (NEMA 5-15P)​​ with three prongs (live, neutral, ground), compatible with Japanese 100V/200V outlets.
• ​​Voltage Rating​​: Supports ​​100–125V AC​​ at 15A, suitable for mid-wattage devices like Catalyst 9300 switches or ISR 1100 routers.
• ​​Safety Certifications​​: ​​PSE (菱形マーク)​​ and ​​JIS C 8303​​ certified for fire resistance and electrical safety.
• ​​Length​​: ​​2 meters (6.56 feet)​​, balancing reach and cable management in racks.
• ​​Connectors​​: ​​IEC 60320 C13​​ to ​​Japanese 3-pin plug​​, ensuring compatibility with Cisco power supplies.

​​Addressing Core User Concerns​​

​​Q: Can I use a generic 3-prong cable in Japan instead?​​
No. Japan’s PSE law requires ​​mandatory certification​​ for all electrical components. Non-compliant cables risk fines, void warranties, or cause connector damage due to mismatched voltage tolerances.

​​Q: Is this cable compatible with high-power devices like Catalyst 9500 chassis?​​
No. The CAB-3P-JPN= is rated for ​​up to 1,875W​​ (125V × 15A). For high-wattage chassis (e.g., 3kW), use Cisco’s ​​CAB-3KAC-JPN=​​ with thicker 12AWG wiring.

​​Q: Does it work with older Cisco 3800/2900 series routers?​​
Yes, provided the device uses an ​​IEC C14 inlet​​. However, always verify voltage requirements—some legacy devices may need step-down transformers.

​​Deployment Scenarios​​

• ​​Tokyo Data Centers​​: Powers Catalyst 9400 switches in colocation facilities adhering to PSE regulations.
• ​​Retail Chains​​: Connects Catalyst 9200 switches to outlets in stores using Japan’s 100V infrastructure.
• ​​Industrial IoT Edge​​: Safely links Cisco IE3400 switches to power in factories with vibration-resistant connectors.

​​Procurement and Compliance​​

The “CAB-3P-JPN=” is available through ITMall.sale. Cisco.com emphasizes its pre-certified design to streamline ​​METI (Ministry of Economy, Trade and Industry)​​ compliance, avoiding delays during regulatory inspections.

​​Final Perspective​​

In Japan’s tightly regulated market, the CAB-3P-JPN= isn’t just a cable—it’s a compliance lifeline. While third-party alternatives might save pennies upfront, they gamble with legal liabilities and operational integrity. For engineers navigating Japan’s stringent standards, this cable is the difference between seamless deployments and costly compliance audits.
