For safe electrical installations, main equipotential bonding is essential to prevent dangerous voltage differences. This bonding bar provides a reliable connection point for multiple conductors, ensuring compliance with lightning protection standards.

Who is it for

Electricians and installers working on building electrical systems, particularly for main equipotential bonding and lightning protection applications. Suitable for surface mounting in indoor environments.

Main features

• Base plate made of grey polystyrene, cover transparent for easy inspection.
• Contact rail made of nickel-plated brass for excellent conductivity and corrosion resistance.
• 7 connections for round conductors 2.5-25 mm² and fine-stranded conductors up to 35 mm².
• 2 connections for flat conductors up to 30x3.5 mm.
• 1 connection for main earthing conductor 7-10 mm.
• Lightning current carrying capacity 100 kA (10/350 µs).
• Complies with DIN EN 62561-1 and VDE 0185-305.
