ESP LN Series
Suitable for systems signalling on up to 8 wires of unshielded twisted
pair cable - protects all 8 pins in each line
Use to protect 1, 4, 8 or 16 lines
Suitable for RS 422/423, 10baseT, 100baseT, Token Ring and Fast
Ethernet systems
Available for individual connections or for multiport applications
Free standing or 19” rack mounted versions available for multiport
applications
Let-through voltage below equipment susceptibility levels
Protects twisted pair lines operating at speeds up to 100 Mbps
Available as 4 or 8 port free standing versions (ESP LN-4 and ESP LN-8)
and 8 or 16 port 19” rack mounted panels (ESP LN-8/16 and
ESP LN-16/16)
Negligible in-line resistance
Sturdy housing and simple plug-in installation
Simple earthing via single braided metal strap
Features and benefits
Use on network cables running within a building to protect systems locally
from transients induced on to data cables from the magnetic field caused by
a lightning strike. Suitable for internal cabling Cat-5.
Protect the network connection to individual pieces of equipment with
the ESP LN
Protect multiport applications such as hubs, switches and patch panels
with the ESP LN-4, ESP LN-8, ESP LN-8/16 or ESP LN-16/16
Application
Combined Category C, B tested protector (to BS EN 61643) suitable
to protect equipment on twisted pair applications using Cat-5
wiring with RJ45 connectors. For use on lines running within
buildings at boundaries up to LPZ 2 through to LPZ 3 to protect
sensitive electronic equipment.
Plug-in connection between
incoming data cables and
equipment to be protected. Make
suitable attachment to earth.
Installation
ESP LN installed on the network connection
to a PC. Note the black earth lead
connection to the chassis of the PC
Protectors for up to Cat-6 cabling with RJ45 connections running external to the building and local protection for PCs and computer
communications with D connectors (cables running within a building), are also available. For protection of legacy coaxial Ethernet networks,
please contact us for details of our ESP ThinNet and ESP ThickNet protectors.
Technical note
ESP LN… range of 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 LN... range of protectors
should not be used in such an
application (up to LPZ 0 A)
where high energy ESP
lightning barriers (such as ESP E
and ESP Cat-5 & Cat-6 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.
