DEHN 472237 barra di equipotenziale PAS I 12AP rame a 12 vie senza coperchio

The DEHN 472237 PAS I 12AP is a 12-point equipotential bonding bar built for main equipotential bonding applications. Unlike basic busbars, it combines a solid copper contact bar with a grey polystyrene base plate, offering a reliable and clearly identifiable connection point for integrating building services into the lightning protection equipotential bonding system.

Highlights

• Copper contact bar for excellent conductivity and corrosion resistance
• 12 connection points with mixed capacities: 10 x 2.5-25 mm², 2 x 25-95 mm²
• Additional connections for flat conductor 30x4 mm and round conductor Ø 8-10 mm
• Surface mounting on a grey polystyrene base plate (RAL 7035)
• Supplied without cover for easy access and inspection

In daily use

The bar is installed on a wall or panel and serves as the central node for connecting protective conductors, bonding conductors, and lightning protection down conductors. The screw terminals accommodate a wide range of conductor sizes, from fine-stranded to solid, ensuring secure and low-resistance connections. The open design allows for quick visual inspection and maintenance.
