Compatibility
The KUPO KHTN414 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 KHTN414 CEE Form Receptacle 16A 4P 380-415V
What are the key features and ratings of the KUPO KHTN414?
The KUPO KHTN414 is a 16A CEE form receptacle (panel-mount female) built to IEC (International Electrotechnical Commission) 60309-1 and 60309-2 standards for 380-415V three-phase power distribution. It features a 4-pole (3P+E) configuration that carries three live conductors and one protective earth conductor, without a neutral return path. The flame-retardant PA6 (Polyamide 6) Nylon housing with nickel-plated brass contacts accepts cables from 1.5-4 mmsq. The IP44-rated housing has a flange dimension of 75 mm and requires a panel cutout of 60 mm.
How does the earth contact design of the KHTN414 enhance electrical safety?
Permanently mounted in panels and enclosures, the KHTN414 16A 380-415V receptacle provides continuous protection for the distribution system it serves. The keyed earth contact at the 6h clock position physically prevents cross-mating with connectors from incompatible voltage systems. The protective earth on this 4-pole (3P+E) connector always engages first and releases last, ensuring the ground path is established before any of the 3 remaining contacts connect. The IP44 (Ingress Protection 44) rating protects the panel-mounted connection against splashing water from all directions and solid objects larger than 1mm, maintaining protection integrity within the enclosure.
How does the IEC 60309 standard ensure the KHTN414 works in multi-vendor installations?
The KUPO KHTN414 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 (4-pole (3P+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 installation steps are required to fit the KHTN414 into a panel enclosure?
Mark and cut the panel opening to the specified cutout dimensions. Insert the receptacle from the front of the panel, align the flange with the mounting surface, and secure using the provided mounting hardware. Wire the terminals from behind the panel, connecting each conductor to its designated terminal. The KHTN414 has a flange dimension of 75 mm and requires a panel cutout of 60 mm. The cable size range for this unit is 1.5-4 mmsq. All terminal screws face the same direction for faster wiring. The IP44 protection is maintained when the housing is properly closed and the cable gland is correctly tightened.
In what environments and industries is the KUPO KHTN414 commonly used?
As a light-duty three-phase receptacle, the KHTN414 serves single workstation power, portable tool feeds, lighting circuits, shore power connections, and HVAC (Heating, Ventilation, and Air Conditioning) service points. Panel-mounted in distribution boxes, switchgear assemblies, and equipment enclosures, it provides a permanent 380-415V connection point for Balanced three-phase loads that do not need a neutral conductor, including motors, pumps, compressors, and other rotating machinery where all three phases are consumed equally.
