• Conductor compatibility: Copper and Aluminum
• Ingress protection: IP66
• Color: Grey
• Material: High-quality thermoplastic

How to use

To install the Hensel RK 0405 T, ensure the power supply is disconnected before beginning any work. Mount the enclosure securely to the desired surface using the provided mounting points. Insert the cables through the appropriate cable entries, ensuring that the seals are properly seated to maintain the IP66 rating. Connect the conductors to the terminal block, ensuring that the screws are tightened to the manufacturer's specified torque to prevent loose connections. Finally, secure the lid firmly to ensure the enclosure is fully sealed.

What to consider before purchase

• Verify that the cable cross-section matches the 4mm2 terminal capacity
• Ensure the mounting surface is flat and stable
• Check if additional cable glands are required for your specific cable diameter
• Confirm that the installation environment does not exceed the IP66 protection limits

Usage recommendations

Always use appropriate tools for tightening terminals to avoid damaging the conductors, especially when working with aluminum wiring. Regularly inspect the enclosure seals during routine maintenance to ensure continued protection against moisture and dust.
