Product Description
The KUPO K2252 is a 32A CEE form inline female connector for 220-415 V three-phase power with neutral for distribution and equipment connections. Built to IEC 60309-1/2:2021 and GB/T11918.1/2-2014, it combines a 3P+N+E, 5-pole layout, 6h keyed earth position, screw terminals, brass contacts with a natural copper finish, and IP67 dust-tight and water-resistant protection for harsher outdoor or washdown environments. The housing uses flame-retardant nylon (PA) + PC, glow-wire 650 °C for dependable connection work on job sites, factory floors, event power systems, and other demanding installations.

Compatibility
The KUPO K2252 is made to IEC 60309 dimensional standards and mates with the listed KUPO compatible products: K025, K0251, K0252. For safe connection, the mating device should match the 32A, 220-415 V, 3P+N+E, 5-pole, IP67, and 6h clock-position ratings shown in the product data.
| 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
Red identifies the three-phase CEE voltage family used for this product rating. The keyed clock position of the earth contact helps prevent cross-mating between incompatible systems, so always confirm amperage, voltage, pole configuration, IP rating, and clock position before installation.
Frequently Asked Questions
What is the KUPO K2252 and what are its primary specifications?
The KUPO K2252 is a 32A CEE form female plug for 220-415V power distribution. Primary specifications: Product type: female plug, 32 A; Rated voltage: 220-415 V; Rated current: 32 A; Earth Contact Position: 6h; Poles: 3P+N+E, 5-pole; Protection grade: IP67; Withstand voltage: AC 2500 V; Insulation resistance: 500 V DC 1 min > 5 MΩ. For K2252, the important distinction is that it is a female plug in the 32A, 220-415V, 3P+N+E, 5-pole, IP67, 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 K2252 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 K2252 documentation, keep the matching K2252 product data sheet with the job file because the certification, withstand-voltage, and insulation-resistance values apply to this specific 32A IP67 female plug variant.
What cable and termination details are listed for the K2252?
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 K2252, 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 K2252?
The product data lists K025, K0251, K0252 as compatible with K2252. For safe mating, the connected product should match the electrical rating, pole configuration, IP rating, and earth contact clock position. For K2252, compatibility with K025, K0251, K0252 depends on the same 32A, 220-415V, 3P+N+E, 5-pole, IP67, 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 K2252 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 K2252 is a 32A IP67 female plug for 220-415V, 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 K2252?
Side-view height shown in dimension drawing: 104 mm Overall length shown in side view: 210 mm Front-view outside diameter / width: 107 mm Cable entry diameter range: Ø 7 - 18 mm Cable nominal cross-section area: 2.5 - 6 mm². Use the K2252 dimensions, including overall length shown in side view 210 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.
