IEC 60320 C20 appliance inlet

IEC 60320 C20 is the appliance-inlet side of the C19/C20 appliance-coupler pairing.

Also called C20 IEC C20 high current IEC inlet

Connector-family identification does not approve a cord, branch circuit or equipment load.

Look for

Confirm C20 at the equipment inlet and use the equipment and cord-set ratings for the actual installation.

The useful distinction

Recognize it. Then verify it.

IEC 60320 C20 is the appliance-inlet side of the C19/C20 appliance-coupler pairing. [C184A]

SCHURTER 4793 is catalogued as an IEC C20 larger appliance inlet; the observed product photos and datasheet identify an equipment-side component, not both ends of a mains cord. [C184B]

The SCHURTER 4793 datasheet identifies a 70°C pin-temperature classification; this is a part/series rating under documented conditions, not an automatic rating for an appliance, installed cord or alternate product. [C184C]

SCHURTER's documented IEC C20 product family identifies the complementary C19 form in the cited mating-product references. Confirm the actual variants and full installed equipment/cordset documentation; no safe-fit or cable-load approval follows solely from that relationship. [C184D]

Exact source example 4793.3000: construction: Front snap-in C20 inlet for1 mm panel; 6.3 x0.8 mm quick-connect terminals; protection class I. pin temperature c: 70. rating: IEC16 A; UL/CSA20 A at250 VAC. Exact listed order number; regional ratings remain distinct. No physical compatibility, pin map or hardware validation is established. [C184E]

Use the source-backed form or position count only for identification. Resolve ratings, protocol, direction, wiring, cable construction and exact device support from the relevant equipment and component documentation.

Before you connect

What to check

  1. Identify the exact connector family and variant from the equipment or cable documentation.
  2. Keep shape, contact count, protocol, electrical rating and device support as separate facts.
  3. Do not force, rewire or adapt a connector from this recognition record; resolve the remaining requirements first.
Trace a supported connection class →

What is not established

This field note does not approve a connection, adapter, cable assembly, rewiring scheme or fabricated part. It intentionally omits unsupported pin assignments and mechanical tolerances.

V141 manufacturer example and safe interpretation

Larger snap-in equipment inlet; the C24 option is not the same exact variant. Verify equipment inlet marking, protection-class variant and cordset documentation. Not established: Installed terminal option, full appliance approval and final cordset compliance. Refer to source S589; no wiring, electrical installation or fit is certified.
