Compatibility
The KUPO KHTN224 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 KHTN224 CEE Form Connector 32A 4P 380-415V
What does the KUPO KHTN224 provide in terms of electrical ratings and design?
The KUPO KHTN224 is a 32A 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 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 2.5-6.0 mmsq. The IP44-rated housing measures 145 mm overall with a body diameter of 72 mm.
What built-in safety features does the KUPO KHTN224 provide?
The KHTN224 connector (inline female), rated for 32A 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 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) splash-proof rating protects this inline connector against water splashes and solid objects larger than 1mm during portable field use.
What determines the mating compatibility of the KHTN224?
The KUPO KHTN224 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 (32A), 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.
How do you open and wire the KUPO KHTN224 for cable assembly?
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 KHTN224 accepts cables from 2.5-6.0 mmsq through a 17 mm cable entry opening. The overall body length is 145 mm with a body diameter of 72 mm. The IP44 protection is maintained when the housing is properly closed and the cable gland is correctly tightened.
Where is the KHTN224 most commonly deployed?
As a medium-duty three-phase connector, the KHTN224 serves catering and event equipment, multi-circuit temporary power distribution, medium industrial machinery, welding equipment, and workshop power feeds. 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.
What types of loads require the 4-pole configuration of the KHTN224?
The KHTN224 uses a 4-pole (3P+E) configuration: three live phases plus protective earth, without a neutral conductor. This configuration is designed for balanced three-phase loads where all three phases are consumed equally and no neutral return path is needed. 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. If the installation requires single-phase circuits derived from the three-phase supply, a 5-pole (3P+N+E) connector with a neutral conductor would be needed instead.
