APC by Schneider Electric PDW18L21-20XC Cable Extender
Overview
The APC by Schneider Electric PDW18L21-20XC is an 18-inch, 5-wire cable extender designed for 20A, 208V power distribution systems. It provides a reliable method to extend existing power circuits, particularly useful in data center or industrial environments where precise power management is critical. The NEMA L21-20P input connector ensures compatibility with standard 20A, 3-phase twist-lock power sources, allowing for flexible deployment in rack-mounted or distributed power setups. This extender is built to maintain power integrity for sensitive equipment.
Compatibility
This cable extender is designed to interface with equipment requiring a NEMA L21-20R receptacle and drawing up to 20A at 208V. It is suitable for extending power from APC by Schneider Electric's rack PDU units or other compatible 20A, 3-phase power distribution systems. It functions as a direct extension for circuits that need to reach devices located slightly further from the primary power source.
Installation Notes
The PDW18L21-20XC features a NEMA L21-20P (plug) and a NEMA L21-20R (receptacle) connector, both rated for 20A, 208V, 5-wire configurations. Ensure the power source is de-energized before connecting the plug. The 18-inch length provides a moderate extension without introducing excessive voltage drop. The cable is constructed with #10 AWG conductors to support the full 20A current rating without overheating. Use appropriate strain relief for the connected equipment.
