Compatibility
The KUPO K0331 is manufactured to IEC 60309 dimensional standards and is compatible with KUPO K1331, K2331, K3331, K4331. For a correct mate, the connected device should share the same 63A rating, 220-250V voltage class, 2P+E, 3-pole configuration, IP44 protection requirement, and 6h earth contact clock position.
| Use with | CEE Form connectors or receptacles with the same amperage, voltage class, pole configuration, IP rating, and earth-contact clock position. |
|---|---|
| Verify before ordering | Amperage, voltage color, pole count, clock position, IP rating, cable diameter, and terminal size. |
| Do not use with | CEE connectors with different current ratings, different voltage classes, non-matching pole configurations, or a different earth-contact clock position. |
Voltage Color Convention
CEE form connectors use standardized housing colors to help identify voltage class. Blue identifies the 200-250V range used by this product class. The keyed clock position of the earth contact helps prevent cross-mating between incompatible voltage systems, so always verify amperage, voltage, pole configuration, and clock position before installation.
Frequently Asked Questions
What is the KUPO K0331 and what are its primary specifications?
The KUPO K0331 is a 63A CEE form male plug for 220-250V power distribution. Primary specifications: Product type: Male Plug, 63 A; Rated voltage: 220-250 V; Rated current: 63 A; Earth Contact Position: 6h; Poles: 2P+E, 3-pole; Protection grade: IP44; Withstand voltage: AC 2500 V; Insulation resistance: 500 V DC 1 min > 5 MΩ. For K0331, the important distinction is that it is a male plug in the 63A, 220-250V, 2P+E, 3-pole, IP44, 6h earth position configuration, so it should be selected for that exact CEE form arrangement rather than a nearby SKU with a different pole count, IP grade, or mounting style.
What safety and compliance standards does the K0331 support?
TUV, CB, CE; RoHS with non-RoHS optional; IEC 60309-1/2:2021 and GB/T11918.1/2-2014. Withstand voltage: AC 2500 V Insulation resistance: 500 V DC 1 min > 5 MΩ Salt spray resistance: > 48 h, no rust Impact test: -25 °C, 16 h, > 0.5 kg, 25°. For K0331 documentation, keep the matching K0331 product data sheet with the job file because the certification, withstand-voltage, and insulation-resistance values apply to this specific 63A IP44 male plug variant.
What cable and termination details are listed for the K0331?
screw terminal. Housing color: blue + grey. Insert color: rust red.; cable entry Ø 16 - 34 mm; cable nominal cross-section area 6 - 16 mm².; Terminal type: Screw terminal. For K0331, size the cable and gland around the listed terminal type Screw terminal.; using the cable assumptions from a larger or smaller KUPO CEE SKU can lead to poor strain relief or an incorrect termination.
Which product is compatible with the K0331?
The product data lists K1331, K2331, K3331, K4331 as compatible with K0331. For safe mating, the connected product should match the electrical rating, pole configuration, IP rating, and earth contact clock position. For K0331, compatibility with K1331, K2331, K3331, K4331 depends on the same 63A, 220-250V, 2P+E, 3-pole, IP44, 6h earth position; a connector with a different current rating, voltage color class, pole layout, IP grade, or clock position should not be treated as interchangeable.
Where is the K0331 typically used?
Designed and manufactured according to IEC 60309-1/2:2021 and GB/T11918.1/2-2014 for factory power distribution, machinery, construction sites, chemical plants, ports, airports, drainage and wastewater projects. Because K0331 is a 63A IP44 male plug for 220-250V, it fits installations that need that exact current capacity, mounting style, and environmental protection level; choose a different KUPO CEE SKU when the site requires another pole layout or ingress rating.
What dimensions are listed for the K0331?
Rendered dimension drawing checked. Overall length 239 mm body length 170 mm side/front height 77 mm front-view outside width 102 mm cable entry Ø 16 - 34 mm 3-contact layout for 2P+E cable nominal cross-section area 6 - 16 mm². Use the K0331 dimensions for this exact body style when checking panel space, cable bend radius, cover swing, and service clearance; similar KUPO CEE products may not share the same envelope.
