The IEC C16 connector is a grounded AC power input interface conforming to the IEC 60320 standard, suitable for electrical couplers. It mates with the corresponding C15 power plug to provide a safe and reliable panel-mount connection point for AC mains power to electrical equipment. The C16 input interface is typically molded from UL94V-0 thermoplastic material, providing a stable and reliable power input.
The C16 connector is rated for approximately 10A/250VAC under international standards, and in North America, it conforms to UL/CSA standards with higher current ratings. Its three-pole grounding connection design makes it ideal for high-temperature environments and heavy-duty applications. Typical applications include office and medical equipment, rack-mount systems, power supplies, kitchen appliances, and other equipment requiring a safe power input solution.

C16 FAQ
C16 is a type of IEC 60320 power inlet that accepts a matching C15 power plug to bring grounded AC mains power into equipment. It’s part of the internationally standardized IEC connector series.
Under the IEC standard, C16 inlets are typically rated for up to about 10 A at 250 VAC. In North America they can be certified up to 15 A at 250 VAC under UL/CSA ratings.
The C16 is designed for higher temperatures and heavier‑duty applications compared with smaller IEC types like C6 or C8. It has a grounded, three‑pole design and generally pairs with C15 connectors for hot‑condition use.
You’ll find C16 inlets on equipment like power distribution units, commercial appliances, IT gear, test instruments, and devices that draw higher current or operate at elevated temperatures.
Only if the replacement matches the same IEC 60320 designation and electrical rating. Using a mismatched inlet could lead to improper fit or unsafe operation.
Yes, C16 is a three‑pole grounded inlet designed to carry line, neutral, and earth ground safely into the device.
