• Additional connection for flat conductors up to 30 x 3.5 mm
• Contact bar material: nickel-plated brass
• Screws: galvanized and chromated steel
• Cover: grey polystyrene (PS)
• Rated impulse current (10/350 µs): 100 kA
• Rated short-circuit current (50 Hz): 100 kA
• Operating temperature range: -40 °C to +80 °C
• Wall mounting

Why choose it

The bar is designed for reliable and durable connections in main potential equalization applications. The nickel-plated brass contact bar ensures low contact resistance and corrosion resistance, while the robust cover protects against accidental contact.

Ideal use cases

• Main equipotential bonding in residential and commercial buildings
• Connecting earthing conductors from lightning protection systems
• Bonding of water, gas, and heating pipes
• Industrial control panels requiring a central earthing point

Good to know

The bar complies with DIN EN 62561-1 (VDE 0185-561-1) and is suitable for indoor use. It accommodates a wide range of conductor sizes, making it versatile for various installation requirements.
