DEHN maadoitusliitin L 140mm teräs sinkitty sinkki 546025

Temporary earthing and short-circuiting of conductors demands a clamp that grips securely and withstands high fault currents. The DEHN 546025 earthing clamp provides a robust screw-clamp connection for round conductors from 6 to 20 mm diameter and flat conductors up to 20 mm width, ensuring reliable equipotential bonding during maintenance work.

Who is it for

Electrical engineers, maintenance technicians, and utility workers who need to establish safe temporary earth connections on copper, aluminum, or steel conductors in substations, switchgear, and overhead line applications.

Main features

• Galvanized zinc finish for high corrosion resistance
• Screw clamp mechanism for strong, vibration-resistant grip
