Total Solution to Earthing & Lightning Protection |

9AKK106354A3360

Combined Category D, C, B tested protector (to BS EN 61643) suitable for use

on ten line LSA-PLUS disconnection modules to PBX telephone exchanges, ISDN

and other telecoms equipment with LSA-PLUS disconnection modules. For use

at boundaries up to LPZ

to protect against flashover (typically the service

entrance location) through to LPZ 3 to protect sensitive electronic equipment.

Telecoms & computer line protection

ESP KT & KE Series

NOTE:

For individual telephone lines and lines at unmanned sites the high performance ESP TN, ready-boxed derivative ESP TN/BX or ESP TN/2BX,

or plug-in ESP TN/JP or ESP TN/RJ11 Series should be used. For plug-in S/T interface ISDN protection, use the ESP TN or ISDN Series protectors.

Installation

Install protectors on all lines that enter or leave each building

(including extensions to other buildings). Identify the lines

requiring protection and plug-in the protector (ensuring the

correct orientation) for a series connection. Plug ESP K10T1/2

directly into each disconnection module requiring protection.

ESP KT1/2 and ESP KT1/PTC must be installed via the ESP

KE10 earth bar. Clip an ESP KE10 on to the disconnection

module and plug an ESP KT1/2 or ESP KT1/PTC in to

each line on the module that needs protecting. In the unlikely

situation that the protector is damaged, it will sacrifice

itself and fail short circuit, taking the line out of commission,

indicating it needs replacing and preventing subsequent

transients from damaging equipment.

For further information on global telephony applications, see

separate Application Note AN005 (contact us for a copy).

Features & benefits

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

–– Very low let-through voltage (enhanced protection to

IEC/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 - avoids confusion when installed together

on the same distribution frame

–– Quick and easy plug-in installation, with ‘bump’

location feedback

–– Under power line cross conditions /PTC versions offer safe

disconnection during fault duration. Unit auto-resets once

fault corrected

–– At larger installations ESP K10T1/2 and ESP K10T1/PTC

provide all in one protection for all ten lines on LSA-PLUS

disconnection modules

–– Use the ESP KE10 to provide trouble free earthing for

up to ten ESP KT1/2 and ESP KT1/PTC (per

disconnection module)

–– ESP K10T1/2 and ESP K10T1/PTC have an integral earth

connection, and an external M4 earth bush for use with

non-metallic LSA-Plus frames

–– ESP KT1/PTC and ESP K10T1/PTC have resettable

overcurrent protection and are rated for power cross faults

–– ESP KT1, ESP KT1/PTC, ESP K10T1 and ESP K10T1/PTC

are suitable for telecoms applications in accordance with

Telcordia and ANSI Standards

Application

–– For PSTN (e.g POTS, dial-up, lease line, T1/E1, *DSL

and Broadband) and U interface ISDN lines, use ESP KT1

(or ESP KT1/PTC) and ESP K10T1 (or ESP K10T1/PTC)

–– For S/T interface ISDN lines, use ESP KT2 and ESP K10T2

–– Protect single lines with ESP KT1, ESP KT2 or

ESP KT1/PTC

–– Protect all ten lines on a disconnection module with

ESP K10T1/2
