Furse ESP KS and KE Series

Combined Category D, C, B tested protector (to BS EN 61643-21) suitable for use on ten line LSA-PLUS disconnection modules to protect individual twised pair data or signal lines. For use at boundaries up to LPZ 0B to protect against flashover (typically the service entrance location) through to LPZ 3 to protect sensitive electronic equipment.

Features and Benefits

  Low cost protection for large numbers of data and signal lines
  Very low let-through voltage (enhanced protection to BS EN 62305) between all lines - Full Mode protection
  Full mode design capable of handling partial lightning currents as well as allowing continual operation of protected equipment
  Repeated protection in lightning intense environments
  Colour of housing distinguishes electrically different protectors to help avoid confusion when installed with other protectors (e.g the ESP KT1/2) on the same distribution frame
  Quick and easy plug-in installation
  Protect only the lines you need
  Ridged finger holds make it easy to obtain a firm grip for installation or removal
  Use the ESP KE10 to provide trouble free earthing for up to ten protectors (per disconnection module)

Data Sheet


Use these units to protect signal, data, control and instrumentation systems with LSA-PLUS disconnection modules.


Install protectors on all data communication and signal lines that enter or leave each building. All protectors must be installed via the ESP KE10 earth bar.

Identify the lines requiring protection and clip the ESP KE10 on to the disconnection modules' earth points. Plug the protector directly into each disconnection module requiring protection (ensuring the correct orientation) for a series connection.

In the unlikely situation that the protector is damaged, it will sacrifice itself and fail short circuit, taking the line out of commission. In addition to indicating that the protector needs replacing, this will also prevent subsequent transients from damaging the equipment.
