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 to 250 V power distribution. It is rated 63 A at 220 to 250 V, with a 2P+E, 3-pole configuration, a 6h earth contact position and IP44 protection. Withstand voltage is AC 2500 V, and insulation resistance is 500 V DC 1 min > 5 MΩ. Choose it for this exact combination of ratings, because nearby CEE form SKUs differ in pole count, IP rating or mounting style.
What safety and compliance standards does the K0331 support?
The K0331 is TÜV, CB and CE certified and is designed and manufactured to IEC 60309-1/2:2021 and GB/T 11918.1/2-2014. It is RoHS compliant, with a non-RoHS option available. Test data: withstand voltage AC 2500 V; insulation resistance 500 V DC 1 min > 5 MΩ; salt spray resistance > 48 h, no rust; low-temperature impact test -25 °C, 16 h, > 0.5 kg, 25°.
What cable and termination details are listed for the K0331?
It uses a screw terminal. Size the cable and gland to these K0331 values. Cable choices made for a larger or smaller CEE form SKU can lead to poor strain relief or an incorrect termination.
Which product is compatible with the K0331?
The K0331 mates with KUPO K1331, K2331, K3331 and K4331. A safe mate needs a connector with the same ratings: 63A, 220 to 250 V, 2P+E, 3-pole, IP44 and 6h earth position. Never treat a connector with a different current rating, voltage color class, pole layout, IP rating or clock position as interchangeable.
Where is the K0331 typically used?
Typical uses include factory power distribution, machinery, construction sites, chemical plants, ports, airports, drainage and wastewater projects. As a 63A IP44 male plug for 220 to 250 V, it suits installations that need this exact current capacity, mounting style and protection level. Choose a different KUPO CEE form SKU when the site needs another pole layout or IP rating.
What dimensions are listed for the K0331?
The full K0331 dimension drawing is in the spec sheet below. Use it for this exact body style when checking panel space, cable bend radius, cover swing and service clearance, because similar CEE form products may differ.
