| CB-4 Serge Arrester |
The Compulogic CB-4 lightning surge arrester is designed to protect data communications equipment installed in locations where there is a high risk of equipment damage due to lightning induced surges.

|
The Compulogic CB-4 provides protection for up to 4 data circuits or 2 x twisted pair signals and is typically installed in series with the data signal lines at a point close to where the cable enters the building or enclosure. Combining both ultra-fast transient suppression semiconductors and ultra high current gas discharge technology the unit offers a high degree of protection from high voltage and high current surges induced into the external cables by nearby lightning strikes.
• Provides repeated protection in lightning intense environments
• Self resetting design
• Low let-through voltage between all lines
• Low in-line resistance
• 35mm DIN rail or bulkhead mounting
• 4 signal wires protected (2 x twisted pair)
• Screen terminal
• Substantial earth stud enables effective earthing
