Product Description
The KUPO K2141 is a 16A CEE form inline female connector for 380-415 V three-phase industrial power distribution. Built to IEC 60309-1/2:2021 and GB/T 11918.1/2-2014, it combines a 3P+E, 4-pole layout, 6h keyed earth position, screw terminals, brass contacts with a natural copper finish, and IP44 splash-proof protection for indoor and covered-site use. The housing uses flame-retardant nylon (PA), glow-wire 650 °C for dependable connection work on job sites, factory floors, event power systems, and other demanding installations.
Key Features
- 16A inline female connector for 380-415 V systems with 3P+E, 4-pole configuration.
- 6h keyed earth position helps prevent mating with incompatible voltage systems.
- IP44 protection helps guard against splashing water and solid objects larger than 1 mm.
- Screw terminals support straightforward field wiring for 1 to 2.5 mm² conductors and Ø 5.5 to 13.5 mm cable entry.
- Brass contacts with a natural copper finish provide a durable current path for repeated industrial use.
- Flame-retardant nylon (PA), glow-wire 650 °C housing supports impact resistance, insulation, and flame-retardant performance.
- Red + gray housing with rust red insert makes the connector easy to identify in a power distribution setup.
- Compatible KUPO counterparts listed for this model: K014, K0141, K0142.

Applications
- Temporary and permanent three-phase industrial power distribution on construction sites, workshops, and factory floors
- Cable assemblies, extension leads, portable equipment, and site distribution boxes
- Light machinery, single workstations, maintenance areas, and general service power
- Ports, airports, drainage and wastewater projects, and other industrial environments
- Entertainment, live event production, and commercial power distribution where CEE compatibility is required
Compatibility
The KUPO K2141 is made to IEC 60309 dimensional standards and mates with the listed KUPO compatible products: K014, K0141, K0142. For safe connection, the mating device should match the 16A, 380-415 V, 3P+E, 4-pole, IP44, 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 K2141 and what are its primary specifications?
The KUPO K2141 is a 16A CEE form female plug for 380 to 415 V power distribution. It is rated 16 A at 380 to 415 V, with a 3P+E, 4-pole configuration, a 6h earth contact position and IP44 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 K2141 support?
The K2141 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 K2141?
It uses a screw terminal. The cable entry accepts cable diameters of Ø 5.5 to 13.5 mm. Conductor cross-section is 1 to 2.5 mm². Size the cable and gland to these K2141 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 K2141?
The K2141 mates with KUPO K014, K0141 and K0142. A safe mate needs a connector with the same ratings: 16A, 380 to 415 V, 3P+E, 4-pole, IP44 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 K2141 typically used?
Typical uses include factory power distribution, machinery, construction sites, chemical plants, ports, airports, drainage and wastewater projects. As a 16A IP44 female plug for 380 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 K2141?
Key K2141 dimensions: Height: 95 mm; Overall length: 157 mm; Front outside diameter: 68 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.
