It features a 3-pole (2P+E) configuration that carries one live conductor, one neutral conductor, and one protective earth conductor. The flame-retardant PA6 (Polyamide 6) Nylon housing with nickel-plated brass contacts accepts cables from 1.0-2.5 mmsq.

The keyed earth contact at the 4h clock position physically prevents cross-mating with connectors from incompatible voltage systems. 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 110-130V reduces the risk of fatal electric shock. In the UK and parts of Europe, BS 7671 wiring regulations mandate 110V center-tapped supplies on construction sites, delivering only 55V to earth. This significantly reduces the risk of fatal electric shock for workers handling the connector in wet conditions.\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"kupo-faq-seo-item\"\u003e\n    \u003ch3\u003eCan the KUPO KHTN013-4 be used with non-KUPO IEC 60309 connectors?\u003c\/h3\u003e\n    \u003cp\u003eThe KUPO KHTN013-4 is manufactured to IEC 60309-1 and IEC 60309-2 dimensional standards, ensuring full interoperability with CEE form connectors from all compliant manufacturers worldwide. To mate correctly, both connectors must share the same amperage rating (16A), voltage class (110-130V), pole configuration (3-pole (2P+E)), and earth contact clock position (4h). The clock position keying acts as a mechanical interlock: a 110-130V connector with a 4h earth position cannot physically engage with a connector keyed to a different clock position, preventing dangerous cross-connections between incompatible electrical systems.\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"kupo-faq-seo-item\"\u003e\n    \u003ch3\u003eWhat steps are involved in preparing and wiring the KHTN013-4?\u003c\/h3\u003e\n    \u003cp\u003eOpen the bayonet twist-lock housing by rotating it counterclockwise, strip the cable conductors to the required length, insert each conductor into its corresponding terminal and tighten the terminal screws. All screws face the same direction for faster, more intuitive wiring. Close the housing by pressing and rotating clockwise until the bayonet locks engage. The KHTN013-4 accepts cables from 1.0-2.5 mmsq through a 15 mm cable entry opening. The overall body length is 120 mm with a body diameter of 53.5 mm. The IP44 protection is maintained when the housing is properly closed and the cable gland is correctly tightened.\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"kupo-faq-seo-item\"\u003e\n    \u003ch3\u003eIn what environments and industries is the KUPO KHTN013-4 commonly used?\u003c\/h3\u003e\n    \u003cp\u003eThe KHTN013-4 is specifically designed for construction site reduced-voltage safety circuits designed to protect workers from electric shock in wet or outdoor conditions.

Common deployments include portable power tool circuits, outdoor maintenance and repair work, temporary lighting on building sites, and any installation where reduced shock risk is a priority.\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"kupo-faq-seo-item\"\u003e\n    \u003ch3\u003eWhy choose the 110-130V KHTN013-4 instead of the standard 220-250V KHTN013?\u003c\/h3\u003e\n    \u003cp\u003eThe KHTN013-4 operates at 110-130V, which is the mandated safety voltage for construction sites in the UK and parts of Europe under BS 7671 wiring regulations. Using a center-tapped 110V transformer, the maximum voltage to earth is only 55V, significantly reducing the risk of fatal electric shock compared to 220-250V mains. The yellow housing and 4-hour clock position physically prevent it from being plugged into a standard 220-250V blue socket, eliminating the risk of connecting reduced-voltage equipment to full mains power.

The keyed earth contact at the 4h clock position physically prevents cross-mating with connectors from incompatible voltage systems. 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 110-130V reduces the risk of fatal electric shock. In the UK and parts of Europe, BS 7671 wiring regulations mandate 110V center-tapped supplies on construction sites, delivering only 55V to earth.

The clock position keying acts as a mechanical interlock: a 110-130V connector with a 4h earth position cannot physically engage with a connector keyed to a different clock position, preventing dangerous cross-connections between incompatible electrical systems.\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"kupo-faq-seo-item\"\u003e\n    \u003ch3\u003eHow do you open and wire the KUPO KHTN213-4 for cable assembly?\u003c\/h3\u003e\n    \u003cp\u003eOpen the bayonet twist-lock housing, prepare the cable by stripping conductors to the specified length, and secure each conductor in its terminal.
