IEC 60309 Connector Validator

Paste an IEC 60309 connector code (for example, 16A 6h 200-250V or 32A 3P+N+E 380-415V IP67) and this tool decodes it into structured attributes — rated current, voltage band, clock position, pole count, color, and ingress protection — then flags any combination that does not exist in the standard. It is built for distributors and catalog teams who need clean, consistent IEC 60309 connector data without hand-checking every supplier line.

What it checks

The validator parses a free-text or coded connector description and verifies each attribute against the IEC 60309 family (formerly IEC 309):

• Rated current — confirms the amperage is one of the standardized ratings (such as 16 A, 32 A, 63 A, and 125 A) rather than a typo like “30A”.
• Voltage band and color — checks that the stated voltage range maps to the correct connector color (for example, low-voltage yellow, 200–250 V blue, 380–480 V red) and flags mismatches.
• Clock position (hour code) — validates the earth-contact “h” position (the keyway clock reference) is legal for the given voltage band.
• Pole configuration — confirms pole-and-earth counts such as 2P+E, 3P+E, or 3P+N+E are consistent with the rest of the code.
• IP / ingress rating — checks any attached protection code (splashproof vs watertight families) is a valid pairing.
• Plug vs socket / surface vs panel — normalizes the connector role so a plug and its mating socket are not stored as if they were the same SKU.

How the IEC 60309 connector standard works

IEC 60309 defines pin-and-sleeve connectors for industrial power, and the genius of the standard is that the physical connector encodes its own electrical rating. Voltage band sets the color, the earth pin’s clock position sets the keyway so incompatible voltages cannot be mated, and the body diameter scales with current. A valid code is therefore not an arbitrary string — every field constrains the others. A “blue 415 V” connector is impossible, and a “63 A 9h” combination is wrong for its band. This tool encodes those interlocking rules and surfaces the contradiction in plain language instead of a silent pass.

All parsing and validation happens client-side in your browser. Nothing you paste is uploaded to a server, which matters when you are running confidential supplier price files or a pre-launch catalog through it. You can check one connector or paste a column of thousands.

The same data-quality pattern shows up far outside electrical distribution. An MRO distributor reconciling fasteners runs into it with thread callouts; a CPG team hits it with pack-size units; a furniture catalog hits it with finish and dimension codes. In every case a coded attribute carries internal rules that a free-text field happily violates. Validating against the standard at ingest is the cheapest place to catch it — long before the bad value reaches a storefront or an AI shopping agent.

FAQ

What does the IEC 60309 connector color mean? +

Color encodes the voltage band. Common conventions are yellow for low voltage (around 100–130 V), blue for 200–250 V, and red for 380–480 V three-phase, with violet and white reserved for other bands. The validator flags any color that does not match the stated voltage so a mislabeled supplier line gets caught at ingest.

What is the 'h' or clock position on an IEC 60309 connector? +

The “h” value (for example, 6h or 9h) is the earth-contact position expressed as a clock reference. It defines the keyway so connectors of different voltages or frequencies cannot be mated by accident. The validator confirms the hour code is legal for the connector’s voltage band.

Is IEC 60309 the same as IEC 309 or CEEform? +

Yes. IEC 60309 is the current designation of the standard previously numbered IEC 309, and “CEEform” is a common informal name for the same pin-and-sleeve connectors. The validator accepts these as the same family.

Does this tool send my data anywhere? +

No. All decoding and validation run entirely in your browser. Nothing is uploaded, so you can safely run confidential supplier files or unreleased catalog data through it.

Can I validate a whole catalog of connectors at once? +

This tool is built for quick, single-value or paste-a-column checks. To validate, normalize, and enrich connector specs across an entire catalog with a source link on every value, see Claro’s automated enrichment approach.
