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/T 11918.1/2-2014, 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.
Key Features

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.
| 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 to 415 V power distribution. It is rated 32 A at 220 to 415 V, with a 3P+N+E, 5-pole configuration, a 6h earth contact position and IP67 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 K2252 support?
The K2252 is TÜV Rheinland, 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 K2252?
It uses a screw terminal. The cable entry accepts cable diameters of Ø 7 to 18 mm. Conductor cross-section is 2.5 to 6 mm². Size the cable and gland to these K2252 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 K2252?
The K2252 mates with KUPO K025, K0251 and K0252. A safe mate needs a connector with the same ratings: 32A, 220 to 415 V, 3P+N+E, 5-pole, IP67 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 K2252 typically used?
Typical uses include factory power distribution, machinery, construction sites, chemical plants, ports, airports, drainage and wastewater projects. As a 32A IP67 female plug for 220 to 415 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 K2252?
Key K2252 dimensions: Height: 104 mm; Overall length: 210 mm; Front outside diameter: 107 mm. Use these figures for this exact body style when checking panel space, cable bend radius, cover swing and service clearance, because similar CEE form products may differ.
