What does the KUPO KHTN613 provide in terms of electrical ratings and design?

The KUPO KHTN613 is an 16 A CEE form inlet (panel-mount male) built to IEC (International Electrotechnical Commission) 60309-1 and 60309-2 standards for 220-250 V single-phase power distribution. 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 1.5-4 mm². The IP44-rated housing has a flange dimension of 75 mm and requires a panel cutout of 60 mm.

How does the KHTN613 protect against cross-mating with incompatible voltage systems?

As a panel-mounted inlet feeding 16 A 220-250 V power into equipment, the KHTN613 prioritizes safe power transfer at the point of entry. The keyed earth contact at the 6h 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. The IP44 (Ingress Protection 44) rating protects the panel-mounted connection against splashing water from all directions and solid objects larger than 1 mm, maintaining protection integrity within the enclosure.

Can the KUPO KHTN613 be used with non-KUPO IEC 60309 connectors?

The KUPO KHTN613 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 (16 A), voltage class (220-250 V), pole configuration (3-pole (2P+E)), and earth contact clock position (6h). The clock position keying acts as a mechanical interlock: a 220-250 V 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 is the KHTN613 mounted into an equipment panel or distribution board?

Cut the panel opening to the specified cutout dimensions. Mount the inlet from the rear of the panel so that the pins protrude through to the front. Secure with mounting hardware and wire the internal conductors to the terminals from behind the panel. The KHTN613 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 mm². 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.

Where is the KHTN613 most commonly deployed?

As a light-duty single-phase inlet, the KHTN613 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 220-250 V connection point for Single-phase loads including lighting, portable tools, general power outlets, workstation feeds, and individual equipment connections.

What distinguishes the 63 A KHTN613 from lower-amperage CEE form connectors?

The 63 A KHTN613 is designed for single workstation power, portable tool feeds, lighting circuits, shore power connections, and HVAC (Heating, Ventilation, and Air Conditioning) service points. Compared to 16 A and 32 A versions, the 63 A tier features significantly larger body dimensions (53 to 68 mm depending on pole count), larger cable accommodation (1.5-4 mm²), and heavier-duty contact construction to handle sustained 63 A loads. IEC 60309 dimensional standards ensure that 63 A connectors cannot mate with 16 A or 32 A sockets, preventing undersized connections. The 63 A tier also includes IP67 watertight variants for the most demanding outdoor installations.

Product Description

Overview

For permanent power infrastructure in workshops, distribution boards, and commercial facilities, the KUPO KHTN613 delivers a 16 A CEE form inlet (panel-mount male) built to IEC (International Electrotechnical Commission) 60309-1 and 60309-2 standards. The flame-retardant PA6 (Polyamide 6) Nylon housing and nickel-plated brass contacts ensure durable, low-resistance performance, while the IP44 (Ingress Protection 44) splash-proof rating and keyed earth contact at the 6-hour clock position provide correctly matched connections throughout the 220-250 V voltage class.

Nickel-plated brass contacts deliver corrosion resistance and reliable low-resistance connections at sustained 16 A loads
All terminal screws face the same direction for faster, more intuitive wiring
Panel-mount design with standardized cutting hole dimensions for straightforward integration into enclosures, distribution boxes, and equipment panels
Blue-coded housing identifies the 220-250 V voltage class per international IEC 60309 color convention
Rated for operation from -25 to 40 °C

Standards

CE marked: Low Voltage Directive 2014/35/EU; IEC/EN 60309-1: 1999 +A1:2007 +A2:2012. General requirements for industrial plugs, socket-outlets and couplers; IEC/EN 60309-2: 1999 +A1:2007 +A2:2012. Dimensional compatibility requirements for pin and contact-tube accessories; RoHS Compliant: Directive 2011/65/EU and (EU)2015/863; REACH Compliant: Regulation No 1907/2006, Article 33(1) Obligation; IP44 Splash-proof.

Applications

Suitable for temporary and permanent power distribution on construction sites, general-purpose single-phase industrial and commercial power, shore power for boats and marinas, light industrial equipment and single workstation power, manufacturing lines and factory floor equipment connections, distribution boards, switchgear assemblies, and equipment panel installations, and entertainment and live event production.

Compatibility

The KUPO KHTN613 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 220-250 V voltage class, preventing cross-connections between incompatible electrical systems.

Voltage Color Convention

IEC 60309 CEE clock face position diagram showing voltage color coding and earth contact positions for 3-pole, 4-pole, and 5-pole configurations

CEE form connectors use internationally standardized housing colors to indicate voltage class: Yellow for 110-130 V, Blue for 200-250 V, Red for 380-480 V, and Black for 500-690 V. 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.
