KATHREIN ZES 11 Earthing Bar, 11-Point Potential Equalization Rail, Nickel-Plated Brass, Screw Terminals

The KATHREIN ZES 11 is an 11-point potential equalization rail engineered for reliable grounding and bonding in electrical installations. Its nickel-plated brass conductor offers low contact resistance and corrosion resistance, while the insulating polystyrene base ensures safe surface mounting.

Overview

This earthing bar provides one main connection for conductors from 6 to 25 mm² and ten branch connections for conductors from 1.5 to 16 mm². Screw terminals with M6 and M5 threads allow secure, tool-tightened connections. The rail is designed for indoor use or in suitable enclosures for outdoor applications, complying with VDE requirements for potential equalization.

What stands out

• 11 connection points: 1 main + 10 branch terminals
• Wide conductor range: 6–25 mm² (main), 1.5–16 mm² (branch)
• Nickel-plated brass rail for durability and conductivity
• Insulating grey polystyrene base for safe mounting
• VDE compliant for potential equalization and lightning protection
