Japan wall plug to IEC 60320 power cords

The wall plug used in Japan on one end and the IEC 60320 inlet on your equipment on the other — C13, C15, C5, C7 or C19. The cord an OEM ships in the box with equipment sold into Japan, and the one an office, lab or shop floor plugs straight into the wall; every cord here carries the approval Japan requires.

Data center power cords for Japan

IEC 60320 jumpers — a C14 or C20 plug into the PDU, a C13, C15 or C19 connector into the server, switch or storage. For most countries these are our global cords: one part number carries the marks Japan requires, so a data center operator deploys the same cord in every region.

Not on the record for Japan yet

  • Industrial cords — IEC 60309 pin-and-sleeve cords, 16–32 A — the international industrial connector, dual-rated for IEC and North American circuits.

We list a cord here only when our certification record shows it is approved for use in Japan or needs no national approval there. Need one of these kinds for Japan? Ask us — we quote the cord and file the approval.

Which certification marks do your cords for Japan carry?

Our cords approved for use in Japan carry ◇PSE Diamond (Category A — Specified Electrical Appliances) on the record. Every product page lists that cord's own approvals, and we can supply the certificate behind any of them.

Which cordage types are accepted in Japan?

VCTF, HVCTF, VCTFK, VFF and VFFK. Our international cords use harmonised H05VV-F / H05RN-F cordage; North American cords use SJT / SJTW.
