CEE Industrial Couplers 400 V (IP44) – Safe and Reliable Jobsite Connections
When building extension cables or extending three-phase power lines on construction sites, in workshops, or across industrial facilities, a dependable coupler is essential. Our CEE 400 V industrial couplers (cable sockets) deliver a stable, tight, and secure connection with CEE plugs in all working conditions.
Engineered for straightforward installation, excellent conductivity, and long-term durability under continuous electrical loads.
Key Benefits and Product Quality:
- Robust Protective Cap & IP44 Rating
An IP44 protection rating ensures reliable defense against solid foreign bodies (greater than 1 mm) and splashing water from all directions. The integrated self-closing spring-loaded cap protects the socket interior from dust and moisture when not connected to a tool or extension cord.
- High-Grade Contacts & Maximum Conductivity
Solid brass contacts ensure optimal power transmission with minimal resistance, eliminating overheating risks. They are built for long-lasting resistance to wear and corrosion, even with frequent plugging and unplugging cycles.
- Ergonomic Housing & Secure Cable Gland
The durable polymer plastic housing withstands heavy impacts and drops on the jobsite. An integrated cable gland provides a tight seal and heavy-duty strain relief, preventing wire pull-outs when cables are tugged or dragged.
Available Configurations and Models:
Depending on your electrical system requirements, CEE 400 V couplers are available in the following options:
- Number of Poles:
- 4-Pole (3P + E) – For three-phase systems without a neutral conductor
- 5-Pole (3P + N + E) – For standard three-phase systems requiring a neutral conductor (N)
- Rated Current (Amperage):
- 16 A – For standard extension leads, smaller workshop machinery, and power tools
- 32 A – For heavy-duty equipment, higher-power electric motors, and mobile distribution units
- 63 A (5P Version) – For heavy industrial applications, large construction sites, and maximum power demands
