The C19 power cord is a high-current electrical connector designed for devices requiring substantial power, adhering to the IEC 60320-C19/C20 standard. It consists of:
C19 Connector (Male): A 3-prong plug with a grounding pin, inserted into the C20 socket of a PDU, UPS, or high-power equipment.
C20 Connector (Female): The corresponding socket on the device end, rated for 16A/20A (or higher in some cases).

2. Typical Applications
A. Data Centers
B. Industrial & Manufacturing
Motor Drives: Supplies power to industrial motors, conveyors, and automation equipment.
Oil/Gas Environments: SJT-jacketed cords resist oils and chemicals in harsh settings.
C. Medical & Scientific
D. Consumer Electronics (Premium Use)
3. How to Select the Right C19 Power Cord?
A. Current & Power Requirements
16A Devices (e.g., standard servers): Choose 3×1.5mm² wire gauge (AWG 14 equivalent).
20A+ Devices (e.g., industrial motors): Opt for 3×2.5mm² (AWG 12) to prevent overheating.
Power Calculation:
Max Power (W)=Voltage (V)×Current (A)(e.g., 220V×20A=4400W)
B. Environmental Adaptability
C. Physical Specifications
Length: Common options: 1.5m, 2m, 3m. Avoid excess length to reduce clutter and tripping hazards.
Color Coding: Use red/orange for critical devices (e.g., servers) and black for general use.
Angle Design: Right-angle connectors save space in tight installations (e.g., behind equipment).
D. Certifications & Safety
4. Safety & Best Practices
Proper Insertion: Align C19 prongs correctly with C20 sockets to avoid bending pins or arcing.
Load Management: Never exceed the cord’s rated current (e.g., avoid using a 16A cord for a 20A device).
Regular Inspection: Check for frayed wires, loose connections, or discoloration every 6 months.
Storage: Coil cables loosely (avoid tight loops) to prevent conductor damage.
Regional Adaptability: Use country-specific adapters (e.g., NEMA L6-20P for the U.S.) if needed.
