Product Description

With earth-first contact engagement, IP44 (Ingress Protection 44) splash-proof protection, and bayonet twist-lock housing, the KUPO KHTN015 is a 16A CEE form plug (inline male) engineered for 380-415V power distribution. The flame-retardant PA6 (Polyamide 6) Nylon housing and nickel-plated brass contacts deliver high impact resistance, corrosion protection, and low-resistance electrical paths under sustained 16A loads. The keyed earth contact at the 6-hour clock position prevents cross-mating with incompatible voltage systems, meeting IEC (International Electrotechnical Commission) 60309-1 and 60309-2 standards.

Compatibility

The KUPO KHTN015 is manufactured to IEC 60309-1 and IEC 60309-2 standards, ensuring dimensional compatibility with CEE form connectors from all compliant manufacturers. The 6-hour clock position earth contact permits mating only with connectors of the same 380-415V voltage class, preventing cross-connections between incompatible electrical systems.

Voltage Color Convention

CEE form connectors use internationally standardized housing colors to indicate voltage class: Yellow for 110-130V, Blue for 200-250V, Red for 380-480V, and Black for 500-690V. The keyed clock position of the earth contact prevents cross-mating between different voltage systems, ensuring only compatible connectors can be joined. Always verify voltage and frequency compatibility with local electrical supply before installation.

Frequently Asked Questions

What makes the KUPO KHTN015 suitable for its intended applications?

The KUPO KHTN015 is a 16A CEE form plug (inline male) built to IEC (International Electrotechnical Commission) 60309-1 and 60309-2 standards for 380-415V three-phase power distribution. It features a 5-pole (3P+N+E) configuration that carries three live conductors, one neutral conductor, and one protective earth conductor for complete power distribution. The flame-retardant PA6 (Polyamide 6) Nylon housing with nickel-plated brass contacts accepts cables from 1.0-2.5 mmsq. The IP44-rated housing measures 133 mm overall with a body diameter of 68 mm.

What safety mechanisms does the KHTN015 include to prevent incorrect connections?

As an inline male plug carrying 16A at 380-415V, the KHTN015 incorporates multiple layers of protection for safe field use. The keyed earth contact at the 6h clock position physically prevents cross-mating with connectors from incompatible voltage systems. The protective earth on this 5-pole (3P+N+E) connector always engages first and releases last, ensuring the ground path is established before any of the 4 remaining contacts connect. The IP44 (Ingress Protection 44) splash-proof rating protects this inline plug against water splashes and solid objects larger than 1mm during portable field use.

Is the KHTN015 compatible with CEE form connectors from other manufacturers?

The KUPO KHTN015 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 (380-415V), pole configuration (5-pole (3P+N+E)), and earth contact clock position (6h). The clock position keying acts as a mechanical interlock: a 380-415V connector with a 6h earth position cannot physically engage with a connector keyed to a different clock position, preventing dangerous cross-connections between incompatible electrical systems.

How is the KHTN015 wired and assembled onto a cable?

Open 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 KHTN015 accepts cables from 1.0-2.5 mmsq through a 12 mm cable entry opening. The overall body length is 133 mm with a body diameter of 68 mm. The IP44 protection is maintained when the housing is properly closed and the cable gland is correctly tightened.

What real-world scenarios call for the KHTN015?

As a light-duty three-phase plug, the KHTN015 serves single workstation power, portable tool feeds, lighting circuits, shore power connections, and HVAC (Heating, Ventilation, and Air Conditioning) service points. As an inline plug, it is used in cable assemblies, extension leads, and portable equipment connections for heavy machinery and motor drives, industrial HVAC (Heating, Ventilation, and Air Conditioning) systems, welding equipment, pump stations, and large-scale power distribution.

Why does the KHTN015 use a 5-pole configuration instead of 4-pole?

The KHTN015 uses a 5-pole (3P+N+E) configuration that carries three live conductors, one neutral conductor, and one protective earth conductor for complete power distribution. 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.
