D/BX Series

Based on the ESP D Series and ESP TN, these protectors are ready-

boxed to IP66 for use in damp or dirty environments. Suitable for

most twisted pair signalling applications. Available for working

voltages of up to 6, 15, 30, 50 and 110 volts and telephone lines

with a maximum working or ringing voltage of 296 volts

Features and benefits

✔

Electronic Systems Protection

For installation in the equipment panel, protectors which are not boxed may be more

suitable. If your system requires a protector with a very low resistance, higher current or

higher bandwidth, use the E or H Series. Unboxed protectors for 3-wire RTD systems are

available - as are plug-in protectors for telephone lines are available.

Low let-through voltage between all lines

Low in-line resistance minimises unnecessary reductions in signal

strength

Ready-boxed to IP66 and supplied ready for flat mounting

Available with screw terminals or with IDC terminals (by using /I suffix

to part number)

Colour coded terminals for quick and easy installation check –

grey for the dirty (line) end and green for clean

Screen terminal enables easy connection of cable screen to earth

Substantial earth stud to enable effective earthing

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

ESP TN/BX and ESP TN/2BX are suitable for telecommunication

applications in accordance with Telcordia and ANSI Standards (see

Application Note AN005)

Supplied as standard with screw terminals – for IDC terminals order

part code plus /I (eg ESP TN/BX/I)

Security alarm panel with ESP TN/BX (bottom) providing

protection from transient overvoltages on the dial-up

telephone line. Note how the ESP TN/BX is earthed via a

bond to the ESP 240-16A/BX (top) installed on the mains

power supply to the panel

| Twisted pair data, signal and telephone lines

Application

Use these ready-boxed protectors

on twisted pair lines in dirty or

damp environments.

For two wire lines, use /BX

versions. For four wire lines,

use /2BX versions.

Installation

Connect in series with the data

communication, signal or

telephone line either near where

it enters/leaves the building or

close to the equipment being

protected. Either way, it must be

very close to the systems earth star

point.
