Compatibility
The KUPO K0231 is manufactured to IEC 60309 dimensional standards and is compatible with KUPO K1231, K2231, K3231, K4231. For a correct mate, the connected device should share the same 32A 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 K0231 and what are its primary specifications?
The KUPO K0231 is a 32A CEE form male plug for 220-250V power distribution. Primary specifications: Product type: Male Plug, 32 A; Rated voltage: 220-250 V; Rated current: 32 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 K0231, the important distinction is that it is a male plug in the 32A, 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 K0231 support?
Certifications listed in product data table: TUV, CB, CE Certification marks shown on PDF: TUV Rheinland Certified, CB, CE Environmental compliance: RoHS; non-RoHS optional Standards referenced: IEC 60309-1/2:2021; GB/T11918.1/2-2014 Withstand voltage: AC 2500 V Insulation resistance: 500 V DC 1 min > 5 MΩ Certification: TUV, CB, CE Salt spray resistance: > 48 h, no rust Impact test: -25 °C, 16 h, > 0.5 kg, 25°. For K0231 documentation, keep the matching K0231 product data sheet with the job file because the certification, withstand-voltage, and insulation-resistance values apply to this specific 32A IP44 male plug variant.
What cable and termination details are listed for the K0231?
Terminal type: Screw terminal; Cable entry diameter range: Ø 7 - 18 mm; Cable nominal cross-section area: 2.5 - 6 mm²; Terminal type: Screw terminal. For K0231, size the cable and gland around the listed cable entry range Ø 7 - 18 mm; conductor cross-section 2.5 - 6 mm²; 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 K0231?
The product data lists K1231, K2231, K3231, K4231 as compatible with K0231. For safe mating, the connected product should match the electrical rating, pole configuration, IP rating, and earth contact clock position. For K0231, compatibility with K1231, K2231, K3231, K4231 depends on the same 32A, 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 K0231 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 K0231 is a 32A 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 K0231?
Overall length shown in side view: 170 mm Body length shown in side view: 135 mm Side-view body height: 63 mm Front-view outside height: 63 mm Cable entry diameter range: Ø 7 - 18 mm Front-view contact layout: 3 contact positions shown, matching 2P+E / 3-pole configuration Cable nominal cross-section area: 2.5 - 6 mm². Use the K0231 dimensions, including overall length shown in side view 170 mm, body length shown in side view 135 mm, 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.
