IEC 60320 C15 versus C15A connectors

Is the cord connector C15 or the distinct C15A very-hot-condition form? Similar naming is not permission to substitute or modify a mains cord.

How they differ

  • IEC 60320 C15 hot-condition cord connector Read the connector designation and the equipment inlet designation instead of relying on a familiar three-contact outline.
  • IEC 60320 C15A very-hot-condition cord connector Identify the exact C15A connector versus its mating C16A inlet from the equipment or cord documentation; do not select, adapt or install a mains-power connection from shape alone.

Trace 9 claims to their source records

C181A · P181

Interpower identifies C15 as the connector side of the C15/C16 IEC 60320 hot-condition appliance-coupler pairing.

Claim scope: V36 catalogue-expansion identification fact only; not independent technical approval, fabrication data, wiring instruction or end-to-end compatibility proof.

Source links: S195 · Evidence trail → (private workspace)

C181B · P181

SCHURTER 4781 is catalogued as an IEC C15 hot-condition cord connector; the observed product photos and datasheet identify a cable-side component, not both ends of a mains cord.

Claim scope: V141 manufacturer-specific IEC mains connector identity, coupling-family example, and thermal classification. NOT installation, cordset approval, dimension, pinout, universal fit, regional plug rating or safe electrical use.

Source links: S586 · Evidence trail → (private workspace)

C181C · P181

The SCHURTER 4781 datasheet identifies a 120°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.

Claim scope: V141 manufacturer-specific IEC mains connector identity, coupling-family example, and thermal classification. NOT installation, cordset approval, dimension, pinout, universal fit, regional plug rating or safe electrical use.

Source links: S586 · Evidence trail → (private workspace)

C181D · P181

SCHURTER's documented IEC C15 product family identifies the complementary C16 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.

Claim scope: V141 manufacturer-specific IEC mains connector identity, coupling-family example, and thermal classification. NOT installation, cordset approval, dimension, pinout, universal fit, regional plug rating or safe electrical use.
