The useful distinction
Recognize it. Then verify it.
IEC 60320 identifies the C22 appliance inlet within the Class I 16 A/20 A coupler family, paired with the C21 connector. [C306A]
Interpower's Rev10-17 chart labels C22 as the appliance inlet paired with C21, in its Class I very hot group. [C306B]
Bulgin's manufacturer overview describes the C22/C21 family as a 3-conductor system with 155 degrees C temperature context. This is not a terminal-position map. [C306C]
SCHURTER identifies 6173.0010 as follows: Front-side snap-in C22 inlet; solder terminals; black PA housing; specified 1.5 mm mounting panel. [C306D]

Specifications and limits
| Documented identification | Interpower’s IEC 60320 overview identifies the C22 appliance inlet with the C21 connector in the Class I 16 A/20 A coupler family. [C306A] |
|---|---|
| Mechanical dimensions | No independently reviewed mechanical drawing in V50; do not use this page for fabrication, fit testing or tolerance work. |
| Engineering pinout | Source-checked engineering profile available; independent review pending. Open engineering profile → |
| Verified device list | Not included. Check exact device and accessory documentation. |
Use only the source-backed family, role or position count for identification. Resolve electrical ratings, protocol generation, lane wiring, signal assignment, cable construction and exact device support from the relevant equipment and component documentation.
Before you connect
What to check
- Identify the exact connector family and variant from the equipment or component documentation.
- Keep physical form, contact count, protocol, electrical rating and device support as separate facts.
- Do not force, rewire, adapt or install from this recognition record; resolve the remaining requirements first.
What is not established
This field note does not approve a connection, adapter, cable assembly, rewiring scheme, energized-work procedure or fabricated part. It intentionally omits unsupported pin assignments and mechanical tolerances.
