Product Information
Full details
The DEHN Earthing Pipe Clamp (540911) is an essential component for electricians and facility managers responsible for installing protective and functional equipotential bonding systems. It excels at providing a reliable, long-lasting electrical connection to pipes ranging from 27mm to 114mm, ensuring compliance with international safety standards like IEC 60364-4-41. While it is built for maximum durability with high-quality materials, users should note that the untreated surface finish requires careful handling to ensure consistent contact in corrosive environments.

FAQs
Can I use this clamp on plastic pipes?
No, this clamp is specifically designed for metal pipes to provide electrical equipotential bonding.
What is the maximum conductor size supported?
The clamp supports conductor cross-sections up to 25mm².
Does this clamp meet VDE standards?
Yes, it is compliant with DIN VDE 0100-410/540.
Can it be used outdoors?
While the stainless steel is durable, ensure it is protected from direct exposure to harsh weather or corrosive chemicals to maintain its lifespan.
How many wires can I attach to one clamp?
The clamp is designed for a maximum of two conductors.
Troubleshooting
Clamp slips on the pipe surface
Ensure the pipe surface is free of oil or debris and tighten the tensioning strap further.
High resistance reading during verification
Remove the clamp, scrape off any paint or oxidation from the pipe surface, and re-install for better metal-to-metal contact.
Pros and Cons
Pros
- Highly versatile clamping range for various pipe sizes
- Supports multiple conductor arrangements
- Meets rigorous international safety standards
- Easy to install with the adjustable tensioning strap
Cons
- Untreated surface may require monitoring in high-humidity areas
- Limited to specific cross-section ranges (4-25mm²)
- Not suitable for non-metallic pipe materials
Setup, Compatibility & Care
- Preparation: Ensure the pipe surface is clean and free of paint, scale, or oxidation where the clamp contact plate will touch to ensure low-resistance connectivity.
- Installation: Wrap the stainless steel tensioning strap around the pipe, feed it through the locking mechanism, and tighten it securely until the clamp does not rotate on the pipe.
- Wiring: Insert the conductor into the terminal port and tighten the screw to the manufacturer's recommended torque to ensure a solid mechanical bond.
- Compatibility: Only use with metal pipes. For painted pipes, verify electrical conductivity using a multimeter after installation.
- Care: Periodically inspect the clamp connection during annual facility maintenance to ensure the tension remains tight and no corrosion has formed at the contact point.
