The protective earth on this 3-pole (2P+E) connector always engages first and releases last, ensuring the ground path is established before any of the 2 remaining contacts connect. Operating at 110-130 V reduces the risk of fatal electric shock. In the UK and parts of Europe, BS 7671 wiring regulations mandate 110 V center-tapped supplies on construction sites, delivering only 55 V to earth.

The critical difference from 4-pole (3P+E) is the inclusion of a neutral conductor. A 4-pole connector carries three live phases plus earth, which is sufficient for balanced three-phase loads like motors and pumps. However, when the installation needs to supply both three-phase and single-phase loads from one connection, a neutral conductor is essential. The 5-pole KHTN015 enables distribution boards and temporary power systems to derive single-phase circuits (line-to-neutral) alongside three-phase feeds, making it the standard choice for event power distribution and mixed-load industrial panels.\" } } ]}\u003c\/script\u003e\u003c!-- ====== END FAQ + JSON SCHEMA BLOCK: KHTN015 --\u003e\u003c!-- ==================== DOWNLOAD SECTION ==================== --\u003e\u003cstyle\u003e.kupo-download-section { margin: 2rem 0 0 0; padding: 0; border: 0; background: transparent; box-sizing: border-box;}.kupo-download-section h2 { margin: 0 0 1rem 0; font-size: 22px !important; font-weight: 700; line-height: 1.4; color: #2C3E50 !important;}.kupo-download-link { display: inline-flex; align-items: center; gap: 0.4rem; font-size: 16px !important; line-height: 1.5; color: #111111 !important; font-weight: 600; text-decoration: underline;}\u003c\/style\u003e\n\u003csection class=\"kupo-download-section\" data-product-id=\"KHTN015\"\u003e \u003ch2\u003eDownload\u003c\/h2\u003e \u003ca class=\"kupo-download-link\" href=\"https:\/\/pub-87314d729f334121b80f91e16c4e7f60.r2.dev\/KHTN015.pdf\" target=\"_blank\" rel=\"noopener\" download\u003e Download KHTN015 Spec Sheet (PDF) \u003c\/a\u003e\u003c\/section\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"KUPO Stage","offers":[{"title":"CEE Form \/ 16A \/ Plug","offer_id":53907593462059,"sku":"KHTN015","price":0.0,"currency_code":"TWD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0999\/6887\/6843\/files\/KHTN015_b.jpg?v=1782111907"},{"product_id":"khtn023","title":"KHTN023 - KUPO CEE Plug 32 A 3P 220-250 V 6h IP44","description":"\u003c!-- KUPO Shopify paste-ready combined HTML for KHTN023 --\u003e\u003c!-- Includes product description, Product JSON-LD, FAQ, FAQ JSON-LD, and Download section. --\u003e\u003cstyle\u003e.kupo-section-title { margin: 1.25rem 0 1rem 0; font-size: 22px !important; font-weight: 700; line-height: 1.3; color: #2C3E50 !important; letter-spacing: 0;}.product-description h3 { color: #2C3E50 !important; font-size: 18px !important; font-weight: bold; margin-top: 1.5rem; margin-bottom: 0.75rem; line-height: 1.35; letter-spacing: 0;}.product-description,.product-description p,.product-description li { color: #222222 !important;}\u003c\/style\u003e\u003ch2 class=\"kupo-section-title\"\u003eProduct Description\u003c\/h2\u003e\u003cdiv class=\"product-description\" data-sku=\"KHTN023\" data-voltage=\"220-250 V\" data-amperage=\"32 A\" data-poles=\"3\" data-ip=\"IP44\"\u003e \u003ch3\u003eOverview\u003c\/h3\u003e \u003cp\u003ePart of KUPO's complete CEE form connector range spanning 16 A to 125 A and 110 V to 400 V, the KHTN023 is a 32 A plug (inline male) designed for 220-250 V 3-pole (2P+E) circuits.

A 4-pole connector carries three live phases plus earth, which is sufficient for balanced three-phase loads like motors and pumps. However, when the installation needs to supply both three-phase and single-phase loads from one connection, a neutral conductor is essential. The 5-pole KHTN225 enables distribution boards and temporary power systems to derive single-phase circuits (line-to-neutral) alongside three-phase feeds, making it the standard choice for event power distribution and mixed-load industrial panels.\" } } ]}\u003c\/script\u003e\u003c!-- ====== END FAQ + JSON SCHEMA BLOCK: KHTN225 --\u003e\u003c!-- ==================== DOWNLOAD SECTION ==================== --\u003e\u003cstyle\u003e.kupo-download-section { margin: 2rem 0 0 0; padding: 0; border: 0; background: transparent; box-sizing: border-box;}.kupo-download-section h2 { margin: 0 0 1rem 0; font-size: 22px !important; font-weight: 700; line-height: 1.4; color: #2C3E50 !important;}.kupo-download-link { display: inline-flex; align-items: center; gap: 0.4rem; font-size: 16px !important; line-height: 1.5; color: #111111 !important; font-weight: 600; text-decoration: underline;}\u003c\/style\u003e\u003csection class=\"kupo-download-section\" data-product-id=\"KHTN225\"\u003e \u003ch2\u003eDownload\u003c\/h2\u003e \u003ca class=\"kupo-download-link\" href=\"https:\/\/pub-87314d729f334121b80f91e16c4e7f60.r2.dev\/KHTN225.pdf\" target=\"_blank\" rel=\"noopener\" download\u003e Download KHTN225 Spec Sheet (PDF) \u003c\/a\u003e\u003c\/section\u003e","brand":"KUPO Stage","offers":[{"title":"CEE Form \/ 32A \/ Connector","offer_id":53907594346795,"sku":"KHTN225","price":0.0,"currency_code":"TWD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0999\/6887\/6843\/files\/KHTN225_b.jpg?v=1782111921"},{"product_id":"khtn2331","title":"KHTN2331 - KUPO CEE Connector 63 A 3P 220-250 V 6h IP44","description":"\u003c!-- KUPO Shopify paste-ready combined HTML for KHTN2331 --\u003e\u003c!-- Includes product description, Product JSON-LD, FAQ, FAQ JSON-LD, and Download section. --\u003e\u003cstyle\u003e.kupo-section-title { margin: 1.25rem 0 1rem 0; font-size: 22px !important; font-weight: 700; line-height: 1.3; color: #2C3E50 !important; letter-spacing: 0;}.product-description h3 { color: #2C3E50 !important; font-size: 18px !important; font-weight: bold; margin-top: 1.5rem; margin-bottom: 0.75rem; line-height: 1.35; letter-spacing: 0;}.product-description,.product-description p,.product-description li { color: #222222 !important;}\u003c\/style\u003e\u003ch2 class=\"kupo-section-title\"\u003eProduct Description\u003c\/h2\u003e\u003cdiv class=\"product-description\" data-sku=\"KHTN2331\" data-voltage=\"220-250 V\" data-amperage=\"63 A\" data-poles=\"3\" data-ip=\"IP44\"\u003e \u003ch3\u003eOverview\u003c\/h3\u003e \u003cp\u003eWith earth-first contact engagement, IP44 (Ingress Protection 44) splash-proof protection, and bayonet twist-lock housing, the KUPO KHTN2331 is a 63 A CEE form connector (inline female) engineered for 220-250 V power distribution.

The 5-pole KHTN415 enables distribution boards and temporary power systems to derive single-phase circuits (line-to-neutral) alongside three-phase feeds, making it the standard choice for event power distribution and mixed-load industrial panels.\" } } ]}\u003c\/script\u003e\u003c!-- ====== END FAQ + JSON SCHEMA BLOCK: KHTN415 --\u003e\u003c!-- ==================== DOWNLOAD SECTION ==================== --\u003e\u003cstyle\u003e.kupo-download-section { margin: 2rem 0 0 0; padding: 0; border: 0; background: transparent; box-sizing: border-box;}.kupo-download-section h2 { margin: 0 0 1rem 0; font-size: 22px !important; font-weight: 700; line-height: 1.4; color: #2C3E50 !important;}.kupo-download-link { display: inline-flex; align-items: center; gap: 0.4rem; font-size: 16px !important; line-height: 1.5; color: #111111 !important; font-weight: 600; text-decoration: underline;}\u003c\/style\u003e\u003csection class=\"kupo-download-section\" data-product-id=\"KHTN415\"\u003e \u003ch2\u003eDownload\u003c\/h2\u003e \u003ca class=\"kupo-download-link\" href=\"https:\/\/pub-87314d729f334121b80f91e16c4e7f60.r2.dev\/KHTN415.pdf\" target=\"_blank\" rel=\"noopener\" download\u003e Download KHTN415 Spec Sheet (PDF) \u003c\/a\u003e\u003c\/section\u003e","brand":"KUPO Stage","offers":[{"title":"CEE Form \/ 16A \/ Receptacle","offer_id":53907594674475,"sku":"KHTN415","price":0.0,"currency_code":"TWD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0999\/6887\/6843\/files\/KHTN415_b.jpg?v=1782111925"},{"product_id":"khtn423","title":"KHTN423 - KUPO CEE Receptacle 32 A 3P 220-250 V 6h IP44","description":"\u003c!-- KUPO Shopify paste-ready combined HTML for KHTN423 --\u003e\u003c!-- Includes product description, Product JSON-LD, FAQ, FAQ JSON-LD, and Download section. --\u003e\u003cstyle\u003e.kupo-section-title { margin: 1.25rem 0 1rem 0; font-size: 22px !important; font-weight: 700; line-height: 1.3; color: #2C3E50 !important; letter-spacing: 0;}.product-description h3 { color: #2C3E50 !important; font-size: 18px !important; font-weight: bold; margin-top: 1.5rem; margin-bottom: 0.75rem; line-height: 1.35; letter-spacing: 0;}.product-description,.product-description p,.product-description li { color: #222222 !important;}\u003c\/style\u003e\u003ch2 class=\"kupo-section-title\"\u003eProduct Description\u003c\/h2\u003e\u003cdiv class=\"product-description\" data-sku=\"KHTN423\" data-voltage=\"220-250 V\" data-amperage=\"32 A\" data-poles=\"3\" data-ip=\"IP44\"\u003e \u003ch3\u003eOverview\u003c\/h3\u003e \u003cp\u003ePart of KUPO's complete CEE form connector range spanning 16 A to 125 A and 110 V to 400 V, the KHTN423 is a 32 A receptacle (panel-mount female) designed for 220-250 V 3-pole (2P+E) circuits.

The critical difference from 4-pole (3P+E) is the inclusion of a neutral conductor. A 4-pole connector carries three live phases plus earth, which is sufficient for balanced three-phase loads like motors and pumps. However, when the installation needs to supply both three-phase and single-phase loads from one connection, a neutral conductor is essential. The 5-pole KHTN435 enables distribution boards and temporary power systems to derive single-phase circuits (line-to-neutral) alongside three-phase feeds, making it the standard choice for event power distribution and mixed-load industrial panels.\" } } ]}\u003c\/script\u003e\u003c!-- ====== END FAQ + JSON SCHEMA BLOCK: KHTN435 --\u003e\u003c!-- ==================== DOWNLOAD SECTION ==================== --\u003e\u003cstyle\u003e.kupo-download-section { margin: 2rem 0 0 0; padding: 0; border: 0; background: transparent; box-sizing: border-box;}.kupo-download-section h2 { margin: 0 0 1rem 0; font-size: 22px !important; font-weight: 700; line-height: 1.4; color: #2C3E50 !important;}.kupo-download-link { display: inline-flex; align-items: center; gap: 0.4rem; font-size: 16px !important; line-height: 1.5; color: #111111 !important; font-weight: 600; text-decoration: underline;}\u003c\/style\u003e\u003csection class=\"kupo-download-section\" data-product-id=\"KHTN4351\"\u003e \u003ch2\u003eDownload\u003c\/h2\u003e \u003ca class=\"kupo-download-link\" href=\"https:\/\/pub-87314d729f334121b80f91e16c4e7f60.r2.dev\/KHTN4351.pdf\" target=\"_blank\" rel=\"noopener\" download\u003e Download KHTN4351 Spec Sheet (PDF) \u003c\/a\u003e\u003c\/section\u003e","brand":"KUPO Stage","offers":[{"title":"CEE Form \/ 63A \/ Receptacle","offer_id":53907595002155,"sku":"KHTN4351","price":0.0,"currency_code":"TWD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0999\/6887\/6843\/files\/KHTN4351_b.jpg?v=1782111929"},{"product_id":"khtn4451","title":"KHTN4451 - KUPO CEE Receptacle 125 A 5P 380-415 V 6h IP67","description":"\u003c!-- KUPO Shopify paste-ready combined HTML for KHTN4451 --\u003e\u003c!-- Includes product description, Product JSON-LD, FAQ, FAQ JSON-LD, and Download section. --\u003e\u003cstyle\u003e.kupo-section-title { margin: 1.25rem 0 1rem 0; font-size: 22px !important; font-weight: 700; line-height: 1.3; color: #2C3E50 !important; letter-spacing: 0;}.product-description h3 { color: #2C3E50 !important; font-size: 18px !important; font-weight: bold; margin-top: 1.5rem; margin-bottom: 0.75rem; line-height: 1.35; letter-spacing: 0;}.product-description,.product-description p,.product-description li { color: #222222 !important;}\u003c\/style\u003e\u003ch2 class=\"kupo-section-title\"\u003eProduct Description\u003c\/h2\u003e\u003cdiv class=\"product-description\" data-sku=\"KHTN4451\" data-voltage=\"380-415 V\" data-amperage=\"125 A\" data-poles=\"5\" data-ip=\"IP67\"\u003e \u003ch3\u003eOverview\u003c\/h3\u003e \u003cp\u003ePart of KUPO's complete CEE form connector range spanning 16 A to 125 A and 110 V to 400 V, the KHTN4451 is a 125 A receptacle (panel-mount female) designed for 380-415 V 5-pole (3P+N+E) circuits.

The critical difference from 4-pole (3P+E) is the inclusion of a neutral conductor. A 4-pole connector carries three live phases plus earth, which is sufficient for balanced three-phase loads like motors and pumps. However, when the installation needs to supply both three-phase and single-phase loads from one connection, a neutral conductor is essential. The 5-pole KHTN635 enables distribution boards and temporary power systems to derive single-phase circuits (line-to-neutral) alongside three-phase feeds, making it the standard choice for event power distribution and mixed-load industrial panels.\" } } ]}\u003c\/script\u003e\u003c!-- ====== END FAQ + JSON SCHEMA BLOCK: KHTN635 --\u003e\u003c!-- ==================== DOWNLOAD SECTION ==================== --\u003e\u003cstyle\u003e.kupo-download-section { margin: 2rem 0 0 0; padding: 0; border: 0; background: transparent; box-sizing: border-box;}.kupo-download-section h2 { margin: 0 0 1rem 0; font-size: 22px !important; font-weight: 700; line-height: 1.4; color: #2C3E50 !important;}.kupo-download-link { display: inline-flex; align-items: center; gap: 0.4rem; font-size: 16px !important; line-height: 1.5; color: #111111 !important; font-weight: 600; text-decoration: underline;}\u003c\/style\u003e\u003csection class=\"kupo-download-section\" data-product-id=\"KHTN6351\"\u003e \u003ch2\u003eDownload\u003c\/h2\u003e \u003ca class=\"kupo-download-link\" href=\"https:\/\/pub-87314d729f334121b80f91e16c4e7f60.r2.dev\/KHTN6351.pdf\" target=\"_blank\" rel=\"noopener\" download\u003e Download KHTN6351 Spec Sheet (PDF) \u003c\/a\u003e\u003c\/section\u003e","brand":"KUPO Stage","offers":[{"title":"CEE Form \/ 63A \/ Inlet","offer_id":53907595428139,"sku":"KHTN6351","price":0.0,"currency_code":"TWD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0999\/6887\/6843\/files\/KHTN6351_b.jpg?v=1782111934"},{"product_id":"khtn6451","title":"KHTN6451 - KUPO CEE Inlet 125 A 5P 380-415 V 6h IP67","description":"\u003c!-- KUPO Shopify paste-ready combined HTML for KHTN6451 --\u003e\u003c!-- Includes product description, Product JSON-LD, FAQ, FAQ JSON-LD, and Download section. --\u003e\u003cstyle\u003e.kupo-section-title { margin: 1.25rem 0 1rem 0; font-size: 22px !important; font-weight: 700; line-height: 1.3; color: #2C3E50 !important; letter-spacing: 0;}.product-description h3 { color: #2C3E50 !important; font-size: 18px !important; font-weight: bold; margin-top: 1.5rem; margin-bottom: 0.75rem; line-height: 1.35; letter-spacing: 0;}.product-description,.product-description p,.product-description li { color: #222222 !important;}\u003c\/style\u003e\u003ch2 class=\"kupo-section-title\"\u003eProduct Description\u003c\/h2\u003e\u003cdiv class=\"product-description\" data-sku=\"KHTN6451\" data-voltage=\"380-415 V\" data-amperage=\"125 A\" data-poles=\"5\" data-ip=\"IP67\"\u003e \u003ch3\u003eOverview\u003c\/h3\u003e \u003cp\u003ePanel installations for 380-415 V 125 A circuits require connectors that combine secure mounting, reliable contact integrity, and protection against incorrect mating.
