Compatibility
The KUPO KHTN215 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
Frequently Asked Questions: KUPO KHTN215 CEE Form Connector 16A 5P 380-415V
What makes the KUPO KHTN215 suitable for its intended applications?
The KUPO KHTN215 is a 16A CEE form connector (inline female) 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 140 mm overall with a body diameter of 68 mm.
How does the KHTN215 protect against cross-mating with incompatible voltage systems?
The KHTN215 connector (inline female), rated for 16A at 380-415V, includes integrated safety mechanisms to protect both the operator and connected equipment. 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 connector against water splashes and solid objects larger than 1mm during portable field use.
Can the KUPO KHTN215 be used with non-KUPO IEC 60309 connectors?
The KUPO KHTN215 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.
What steps are involved in preparing and wiring the KHTN215?
Open the bayonet twist-lock housing, prepare the cable by stripping conductors to the specified length, and secure each conductor in its terminal. The contact tubes inside the connector receive the plug's pins during mating. Close the housing by pressing and rotating clockwise until the bayonet locks click into place. The KHTN215 accepts cables from 1.0-2.5 mmsq through a 12 mm cable entry opening. The overall body length is 140 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 KHTN215?
As a light-duty three-phase connector, the KHTN215 serves single workstation power, portable tool feeds, lighting circuits, shore power connections, and HVAC (Heating, Ventilation, and Air Conditioning) service points. As an inline connector, 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 KHTN215 use a 5-pole configuration instead of 4-pole?
The KHTN215 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 KHTN215 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.
