CEE 110V Yellow Connectors

Yellow CEE connectors identify the 100 to 130V voltage range under the IEC 60309 standard, with an earth pin at the 4-hour clock position. The 110V reduced-voltage system is widely specified on construction sites and outdoor work environments where safety regulations require lower operating voltages to minimize the risk of electric shock. In the UK and many Commonwealth countries, 110V center-tapped earth (CTE) systems are standard practice on building sites. KUPO's yellow CEE connectors are available in 3-pole (2P+E) configuration across 16A and 32A ratings, with PA6 nylon housings and nickel-plated brass contacts. The 4h clock keying ensures these connectors cannot physically mate with 230V blue or 400V red outlets.
