Product Description
The KUPO K4452 is a 125A CEE form concealed inclined female socket with hinged cover for 220-415V power distribution. Its angled, panel-mount format keeps the connection easy to reach inside enclosures and distribution boxes, while the 6h keyed earth position helps ensure it mates only with matching CEE devices. With screw terminals, brass contacts with natural copper finish, and a flame-retardant nylon (PA) + PC housing with glow-wire 650 °C, it is built for practical daily use in industrial, commercial, and site-power installations.

Compatibility
The KUPO K4452 follows IEC 60309 dimensional conventions and is listed for use with KUPO K0452. For a correct connection, match the connected device to the same 125A, 220-415V, 3P+N+E, 5-pole, IP67, and 6h rating shown for this socket.
| 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 indicate voltage class. Red identifies common three-phase CEE supply ranges, matching this 220-415V socket class. The keyed clock position of the earth contact helps prevent cross-mating between incompatible systems, so always verify amperage, voltage, pole configuration, IP rating, and clock position before installation.
Frequently Asked Questions
What is the KUPO K4452?
The KUPO K4452 is a 125A concealed inclined female CEE socket with a hinged cover for 220-415V power distribution. It mounts into panels, enclosures, and distribution boxes, giving installers an angled connection point that is easier to access while keeping the socket protected. For K4452, the important distinction is that it is a concealed inclined female socket with hinged cover in the 125A, 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 ratings need to match when using the K4452?
Match the mating connector to the same 125A, 220-415V, 3P+N+E, 5-pole, IP67, and 6h earth position. The keyed earth clock position helps prevent cross-mating with incompatible CEE voltage systems. For K4452, the matching set is 125A, 220-415V, 3P+N+E, 5-pole, IP67, 6h earth position; keeping those values together prevents accidental pairing with a visually similar KUPO CEE product from another voltage, pole, or protection class.
What does the IP67 rating mean for this socket?
The K4452 has IP67 watertight protection for harsher wet or dusty areas. The rating helps protect the socket against dust ingress and temporary immersion when it is installed and closed correctly. On K4452, the IP67 rating should be considered together with the concealed inclined female socket with hinged cover body, matching cover or mating connector, and cable-entry seal so the installed assembly maintains the intended protection level.
Which KUPO product is compatible with the K4452?
The product data lists KUPO K0452 as the compatible mating product. Always confirm the connected product carries the same current, voltage, pole configuration, IP rating, and clock position before installation. For K4452, compatibility depends on the same 125A, 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.
What should installers check before mounting the K4452?
Before installation, wire through the screw terminals, confirm the listed cable cross-section area of 16 - 50 mm², check the 110 × 115 mm faceplate size, and use the 90.5 × 90.5 mm mounting-hole spacing. The product data also lists brass contacts with natural copper finish and a flame-retardant nylon (PA) + PC housing with glow-wire 650 °C for durable industrial use. For K4452, confirm the conductor size, cable gland fit, and screw-terminal preparation against the K4452 drawing before assembly, because these installation limits vary across the KUPO CEE range.
Where is the K4452 typically used?
The K4452 is suited to three-phase power where neutral and earth conductors are required, including machinery, control panels, distribution boards, switchgear assemblies, construction-site panels, and event or service-power installations. Because K4452 is a 125A IP67 concealed inclined female socket with hinged cover 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.
