Compatibility
The KUPO KHTN213-4 is manufactured to IEC 60309-1 and IEC 60309-2 standards, ensuring dimensional compatibility with CEE form connectors from all compliant manufacturers. The 4-hour clock position earth contact permits mating only with connectors of the same 110-130V 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 KHTN213-4 CEE Form Connector 16A 3P 110-130V
What are the key features and ratings of the KUPO KHTN213-4?
The KUPO KHTN213-4 is a 16A CEE form connector (inline female) rated for 110-130V reduced-voltage safety circuits, commonly deployed on construction sites to protect workers from electric shock. It features a 3-pole (2P+E) configuration that carries one live conductor, one neutral conductor, and one protective earth conductor. 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 130 mm overall with a body diameter of 52 mm.
How does the KHTN213-4 contribute to worker safety on construction sites?
The KHTN213-4 connector (inline female), rated for 16A at 110-130V, includes integrated safety mechanisms to protect both the operator and connected equipment. The keyed earth contact at the 4h clock position physically prevents cross-mating with connectors from incompatible voltage systems. The protective earth on this 3-pole (2P+E) connector always engages first and releases last, ensuring the ground path is established before any of the 2 remaining contacts connect. Operating at 110-130V reduces the risk of fatal electric shock. In the UK and parts of Europe, BS 7671 wiring regulations mandate 110V center-tapped supplies on construction sites, delivering only 55V to earth. This significantly reduces the risk of fatal electric shock for workers handling the connector in wet conditions.
What determines the mating compatibility of the KHTN213-4?
The KUPO KHTN213-4 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 (110-130V), pole configuration (3-pole (2P+E)), and earth contact clock position (4h). The clock position keying acts as a mechanical interlock: a 110-130V connector with a 4h 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 KHTN213-4 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 KHTN213-4 accepts cables from 1.0-2.5 mmsq through a 15 mm cable entry opening. The overall body length is 130 mm with a body diameter of 52 mm. 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 KHTN213-4 commonly used?
The KHTN213-4 is specifically designed for construction site reduced-voltage safety circuits designed to protect workers from electric shock in wet or outdoor conditions. It is the standard connector for UK and European construction sites mandating 110V center-tapped supplies under BS 7671 wiring regulations. Common deployments include portable power tool circuits, outdoor maintenance and repair work, temporary lighting on building sites, and any installation where reduced shock risk is a priority.
Why choose the 110-130V KHTN213-4 instead of the standard 220-250V KHTN213?
The KHTN213-4 operates at 110-130V, which is the mandated safety voltage for construction sites in the UK and parts of Europe under BS 7671 wiring regulations. Using a center-tapped 110V transformer, the maximum voltage to earth is only 55V, significantly reducing the risk of fatal electric shock compared to 220-250V mains. The yellow housing and 4-hour clock position physically prevent it from being plugged into a standard 220-250V blue socket, eliminating the risk of connecting reduced-voltage equipment to full mains power. Choose the KHTN213-4 for any site where regulations or safety policy require reduced-voltage power distribution.
