Furse lightning protectors for data & signal lines with LSA-PLUS modules

Home › Lightning & Surges Protection › Electronic Systems Protection

Suitable for use on ten line LSA-PLUS disconnection modules.
Protect individual twisted pair data or signal lines, in conjunction with the ESP KE10.

For PSTN and U interface ISDN lines on LSA-PLUS modules, use the ESP KT1 or ESP K1. For S/T interface ISDN lines on LSA-PLUS modules, use the ESP KT2 or ESP K10T2.

Application

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

Single line protectors installed on LSA-PLUS disconnection modules, via ESP KE10 earth bars;on all incoming signal and data lines.

Features and benefits

Low cost protection for large numbers of data and signal lines.

Low let-through voltage between all sets of conductors.

Multiple strike protection, with the ability to protect against at least ten 5kA transients (test to ITU K20).

ESP KS06

Colour of housing distinguishes electrically different protectors to help avoid confusion when installed with other protectors(eg 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 KE10to provide trouble free earthing for up to ten protectors (per disconnection module).

UK Oftel Approval NS/G/1235/W/100025.

Installation

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.

Having pushed the ESP KE10 earth baron to the disconnection modules' earth points,firmly push an ESP KS06 (or ESP KS15,ESP KS30 or ESP KS50) into each line/pair requiring protection

If the protector's ratings are exceeded, 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.
