Combined Category C, B tested protector (to BS EN 61643) suitable to protect
PCs and other computer equipment on systems using 9, 15 or 25 pins. For use
on lines running within buildings at boundaries up to LPZ 2 through to LPZ 3
to protect sensitive electronic equipment.
Telecoms & computer line protection
ESP LA & LB Series
TECHNICAL NOTE:
ESP LA... and ESP LB... protectors are designed only for use on cables
running within a building (typically LPZ 2) to offer local protection to equipment. They therefore
will not be able to handle the higher level transients that occur when lines between buildings
are protected. ESP LA... and ESP LB... protectors should not be used in such an application
(up to LPZ
0
) where high energy ESP lightning barriers (such as ESP E Series) should be
employed. If they are used in lines between buildings, there is a high risk of the protector
being overloaded and destroyed during transient activity. Connected equipment will, in most
cases, still be protected, but there is a small risk that equipment will suffer damage in
such circumstances.
Installation
Simple plug-in connection to the communication port,
between the equipment to be protected and its incoming
data cable. Make suitable attachment to earth.
Full product range order codes can be found on pages 17/8-17/9
NOTE:
For cabling up to Cat-6 with RJ45 connections (running external to the building) and local protection for up to Cat-6 with RJ45 connections,
(running within a building) products are also available. For protection of legacy coaxial Ethernet networks, please contact us for details of our ESP ThinNet
and ESP ThickNet protectors.

Application
Use on cables running within a building to protect equipment
locally from transients induced on to data cables from the
magnetic field caused by a lightning strike.
–– For Asynchronous RS 232 systems, use ESP LA-5/25
–– For RS 232 systems, use ESP LA-25/25, ESP LA-9/9
or ESP LA-15/15
–– For RS 422, RS 423 and RS 485 systems, use ESP
LB-9/9, ESP LB-15/15 or ESP LB-25/25
