Product Description
The KUPO K4131 is a 16A CEE form concealed inclined female socket with hinged cover for 220-250V 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 K4131 follows IEC 60309 dimensional conventions and is listed for use with KUPO K013, K0131, and K0132. For a correct connection, match the connected device to the same 16A, 220-250V, 2P+E, 3-pole, IP44, 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. Blue identifies the 200-250V CEE range, matching this 220-250V socket. 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 K4131?
The KUPO K4131 is a 16A concealed inclined female CEE socket with a hinged cover for 220-250V 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 K4131, the important distinction is that it is a concealed inclined female socket with hinged cover in the 16A, 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 ratings need to match when using the K4131?
Match the mating connector to the same 16A, 220-250V, 2P+E, 3-pole, IP44, and 6h earth position. The keyed earth clock position helps prevent cross-mating with incompatible CEE voltage systems. For K4131, the matching set is 16A, 220-250V, 2P+E, 3-pole, IP44, 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 IP44 rating mean for this socket?
The K4131 has IP44 splash-proof protection for panel and enclosure installations where the socket may face splashing water or small solid objects. It is a practical choice for general industrial, commercial, and temporary power locations when the connected equipment carries the same rating. On K4131, the IP44 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 products are compatible with the K4131?
The product data lists KUPO K013, K0131, and K0132 as compatible mating products. Always confirm the connected product carries the same current, voltage, pole configuration, IP rating, and clock position before installation. For K4131, compatibility with KUPO K013, K0131, and K0132 depends on the same 16A, 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.
What should installers check before mounting the K4131?
Before installation, wire through the screw terminals, confirm the listed cable cross-section area of 1 - 2.5 mm², check the 85 × 85 mm faceplate size, use the 70 × 70 mm mounting-hole spacing, and allow for the 76 mm circular opening shown in the front view. 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 K4131, confirm the conductor size, cable gland fit, and screw-terminal preparation against the K4131 drawing before assembly, because these installation limits vary across the KUPO CEE range.
Where is the K4131 typically used?
The K4131 is suited to single-phase industrial and commercial power, construction-site panels, factory equipment, workstation power, and event or service-power installations. Because K4131 is a 16A IP44 concealed inclined female socket with hinged cover 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.
