C20 to C21 Power Cords: Heavy-Duty Connectivity for Data Centers

Introduction to C20 to C21 Power Cords

In the world of data centers and server rooms, reliable power connectivity is paramount. CableLeader's C20 to C21 power cords offer a robust solution for connecting devices with C21 receptacles to PDUs or UPS systems equipped with C20 connectors. These heavy-duty 12 AWG cords are designed to handle the demanding power requirements of mission-critical infrastructure, ensuring reliable and efficient power delivery.

Connectors: C20 and C21 Explained

The IEC-60320-C20 connector is a two-pin male plug commonly found on power distribution units (PDUs) and uninterruptible power supplies (UPS). It is designed to mate with the IEC-60320-C21 female receptacle, which is typically present on servers, computers, and other high-power devices in data centers.

These connectors are specifically engineered for high-temperature environments, with the C21 receptacle capable of withstanding temperatures up to 155°C (311°F), making it ideal for demanding applications that generate significant heat. The C20 plug, on the other hand, is rated for temperatures up to 70°C (158°F).

Compatibility and Versatility

CableLeader's C20 to C21 power cords are available in various lengths, ranging from 3 feet to 15 feet, offering flexibility to extend existing power connections or accommodate various rack configurations.
