OBO BETTERMANN 1809 M Equipotential Bonding Bar, 10 Connection Points, Grey/Transparent, IP20, 5015844

For reliable potential equalization in indoor electrical installations, the OBO BETTERMANN 1809 M equipotential bonding bar offers a robust solution with a nickel-plated brass contact rail and a grey polystyrene base plate. Unlike basic terminal strips, this unit provides 10 distinct connection points for main, medium, and small conductors, ensuring secure bonding across various conductor types. The transparent cover allows quick visual inspection while protecting against accidental contact (IP20).

Highlights

• 10 connection points: 1 main conductor terminal (flat 30x3.5 mm or round 8-10 mm), 2 medium conductor terminals (round 7-10 mm or flat 30x3.5 mm), and 7 small conductor terminals (2.5-25 mm² solid/stranded, up to 16 mm² fine-wire).
• Nickel-plated brass contact rail ensures low contact resistance and corrosion resistance.
• Grey polystyrene base plate and transparent cover for durability and easy inspection.
• Surface-mounted design with IP20 protection, ideal for indoor use.
• Complies with DIN VDE 0100-410, DIN VDE 0100-540, and DIN VDE 0185-305 (IEC 62305).

In daily use

Installation is straightforward: mount the bar on a flat surface, connect the main equipotential bonding conductor to the large terminal, and then attach individual protective conductors to the smaller terminals. The transparent cover snaps on to prevent accidental contact while allowing visual verification of connections. The bar's compact design fits easily into distribution boards or equipment rooms, and the included screws (steel, electro-galvanised, passivated) ensure secure clamping. Whether for new installations or retrofits, this bonding bar provides a dependable means to equalize potentials and enhance electrical safety.
