Compatibility
The KUPO KHTN424 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 KHTN424 CEE Form Receptacle 32A 4P 380-415V
What are the key features and ratings of the KUPO KHTN424?
The KUPO KHTN424 is a 32A 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 4-16 mmsq. The IP44-rated housing has a flange dimension of 90 mm and requires a panel cutout of 73 mm.
How does the KHTN424 protect against cross-mating with incompatible voltage systems?
Permanently mounted in panels and enclosures, the KHTN424 32A 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.
Can the KUPO KHTN424 be used with non-KUPO IEC 60309 connectors?
The KUPO KHTN424 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.
What are the panel cutout requirements for installing the KHTN424?
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 KHTN424 has a flange dimension of 90 mm and requires a panel cutout of 73 mm. The cable size range for this unit is 4-16 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 KHTN424 commonly used?
As a medium-duty three-phase receptacle, the KHTN424 serves catering and event equipment, multi-circuit temporary power distribution, medium industrial machinery, welding equipment, and workshop power feeds. 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.
What types of loads require the 4-pole configuration of the KHTN424?
The KHTN424 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.
