Warna steker industri adalah penanda keluarga tegangan; kode jamnya, seperti 4h, 6h atau 9h, mengidentifikasi posisi pengkodean mekanis. Baca keduanya bersama dengan susunan kutub dan peringkat yang tercetak. Biru tidak mengidentifikasi setiap fitur konektor, dan 6h tidak selalu berarti 230 V.
Panduan ini mencakup sistem pembacaan pin-dan-selongsong IEC 60309 yang umum untuk aksesori di atas 50 V. Untuk perbedaan yang lebih luas antara steker, kopling kabel, soket, dan inlet peralatan, lihat Steker dan Soket Industri Dijelaskan.
Tetapkan Tampilan Sebelum Membaca Jam
Untuk aksesori di atas 50 V, baca tab kontak ground dalam tampilan depan soket, keyway pada pukul enam. Steker yang sesuai mempertahankan kode tersebut: IEC 60309-2:2021, klausul 7.1, contoh publik, halaman cetak 11.
Baca tampilan referensi sebagai berikut:
- Hadapkan sisi pasangan soket.
- Putar keyway utama ke bawah.
- Bandingkan posisi kontak arde dengan tampilan jam.
Dalam tampilan tersebut, 6h berada di bawah, 9h berada di kiri, dan 4h berada ke arah kanan bawah. Huruf h mencatat posisi jam; ini bukan durasi atau jumlah fase.
Orientasi bagian depan soket bukanlah peta terminal belakang. Gunakan gambar pabrikan untuk identifikasi terminal; jangan menetapkan terminal dari foto yang tidak berlabel.
Kombinasi Warna dan Jam Umum dalam Katalog YOCL
Tabel di bawah ini adalah pencarian katalog YOCL pilihan, bukan reproduksi dari setiap IEC kombinasi tegangan/frekuensi. Nilai dan pengenal model berasal dari YOCL IP44 tabel colokan industri.
| Warna bodi | Susunan kutub | Tegangan operasi terdaftar | Posisi jam | Contoh model | Arus terdaftar |
|---|---|---|---|---|---|
| Kuning | 2P+E | 110–130 V | 4j | NM-013H-4 | 16 A |
| Biru | 2P+E | 220–240 V | 6 jam | NM-013H | 16 A |
| Merah | 3P+E | 380–415 V | 6 jam | NM-014H | 16 A |
| Merah | 3P+N+E | 220–380 / 240–415 V, as listed | 6 jam | NM-015H | 16 A |
| Merah | 2P+E | 380–415 V | 9h | NM-013L-9 | 16 A |
| Biru | 3P+E | 220–240 V | 9h | NM-014L-9 | 16 A |
E denotes protective earth; N denotes neutral. The pole expressions above correspond to three, four and five main contacts respectively. A three-contact 2P+E expression alone does not identify the circuit as phase-plus-neutral rather than phase-plus-phase; read the supply and terminal documentation.
For the five-contact row, the voltage text is preserved from the catalogue. Do not turn its paired notation into a single assumed supply voltage. Confirm the intended phase-to-neutral and phase-to-phase values when specifying that model.
The selected plug tables do not state a frequency for these rows. The YOCL range selector requests frequency as a separate specification input, so record it rather than assuming a catalogue omission means unrestricted use.
What the Colours Let You Recognize
Within these catalogue examples, yellow identifies the listed 110–130 V option, blue the listed 220–240 V options, and red the listed 380–415 V options and the five-contact paired-voltage entry. These are useful visual starting points for sorting the catalogue.
The printed operating-voltage marking is the precise input. A nominal supply label, a broad colour-code band and a particular model’s declared voltage range should not be treated as interchangeable. Other colour bands, frequency-specific configurations and regional series need their own applicable table; this shortlist cannot select them.
Read the Pole Row Before the Clock Sector
A circular clock chart can contain several rings. Start with the ring for the actual pole arrangement, then read its voltage/frequency sector and earth position. Reading the same sector across a different ring can produce a different connector specification.
Two comparisons from the table make the problem concrete.
Same Blue Colour, Different Clock Codes
NM-013H and NM-014L-9 are both listed as blue, 16 A and 220–240 V. However:
- NM-013H: 2P+E, three contacts, 6 jam.
- NM-014L-9: 3P+E, four contacts, 9h.
A request for a “blue 16 A industrial plug” leaves the pole arrangement and clock designation unresolved. The two rows describe different interfaces, despite sharing colour, current and listed voltage.
Same 6h Code, Different Voltage and Contacts
NM-013H and NM-014H both have a 6h designation and a listed 16 A rating. The first is blue, 2P+E and 220–240 V; the second is red, 3P+E and 380–415 V.
Consequently, “6h plug” is incomplete, just as “blue plug” is incomplete. Clock coding needs the other fields to become a meaningful specification. Neither example establishes permission to adapt one circuit to another.
Separate the Information on the Marking
Separate current, clock code and voltage before comparing parts. Below, NM-013H’s catalogue values appear as three external annotations, rather than a transcription of a physical rating plate.
Use this record when reading a product or requesting its mating part:
| Record separately | What to copy or confirm |
|---|---|
| Component format | Plug, portable cable coupler, fixed socket or appliance inlet |
| Susunan kutub | Full expression, such as 2P+E or 3P+N+E |
| Arus terukur | Exact ampere value and applicable size series |
| Operating voltage and supply | Full marking, including paired values and AC/DC identification where given |
| Frekuensi | Published marking or confirmed model specification |
| Clock designation | Complete number plus h, interpreted in the correct reference view |
| Environmental and mechanical details | Required protection, locking arrangement, cable entry or mounting format |
| Mating accessory | Exact existing part identifier, photograph and manufacturer’s compatibility confirmation |
Colour can accompany this record, but cannot replace its electrical or mechanical fields. Likewise, an IP marking concerns protection and does not tell you the clock position.
Where This Reading Method Stops
At or below 50 V, the minor key supplies the clock reference, relative to the major key. This guide’s earth-contact rule does not apply.
Special supply systems need the full applicable reference. Do not fill unlisted clock sectors with guesses or select a high-frequency or DC connector from a familiar mains-colour example. Check the relevant standard configuration and the model’s documentation.
Coding is not an installation approval. IEC 60309-1:2021 covers general accessory requirements; IEC 60309-2:2021 addresses dimensional compatibility for standardized pin-and-contact-tube accessories. IEC’s current Part 2 publication includes an August 2026 correction. The clause-reading explanations here use the accessible original 2021 sample; that sample is not the full corrected publication or evidence of any individual product’s certification.
For a replacement, use the existing accessory’s full designation to start the enquiry. YOCL’s industrial plugs and sockets range dan IP44 cable coupler catalogue provide product routes. Send the specification record and the existing mating-part details for confirmation before ordering; the clock diagram does not establish wiring, circuit protection or suitability for the installation.
