Use these protectors on network cables that travel between buildings to
prevent damage to equipment, e.g. computers, servers, repeaters and hubs.
Suitable for computer networks up to Cat-6 cabling.
✔
To protect up to 100baseT and up to 1000baseT networks with
Cat-5/Cat-5e cabling use ESP Cat-5e and ESP Cat-5e/Gb respectively
✔
To protect up to 10GbaseT networks with Cat-6 cabling use ESP Cat-6
✔
To protect up to 100baseT, 1000baseT and 10GbaseT Power over
Ethernet (PoE) networks use ESP Cat-5e/PoE, ESP Cat-5e/Gb/PoE and
ESP Cat-6/PoE respectively

Technical note
The interfaces used in Ethernet
networks incorporate an
isolation transformer which
gives these systems an inbuilt
immunity to transients
between line and earth of
1,500 Volts or more.

✔
Suitable for systems signalling on up to eight wires of either shielded
or unshielded twisted pair cable
✔
Very low let-through voltage (enhanced protection to 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
✔
Unlike some competing devices, the ethernet SPDs provide effective
protection without impairing the system’s normal operation
✔
Low capacitance circuitry prevents the start-up signal degradation
associated with other types of network protector
✔
Low in-line resistance minimises unnecessary reductions in signal
strength to maximise signalling distance
✔
Sturdy ABS housing with convenient holes for flat mounting, or
vertically via TS35 ‘Top Hat’ DIN rail
✔
Substantial earth connection to enable effective earthing
✔
Supplied with short (50 cm) Cat-5e UTP or Cat-6 STP cable to enable
neat installation
Features and benefits
Application
Combined Category D, C, B tested protector (to BS EN 61643)
suitable to protect twisted pair Ethernet networks, including
Power over Ethernet (PoE), with RJ45 connections. For use at
boundaries up to LPZ
0
B
to protect against flashover (typically the
service entrance location) through to LPZ 3 to protect sensitive
electronic equipment.
ESP CAT5e/UTP-1
1 metre cable with unshielded
RJ45 connections
ESP CAT6/STP-1
1 metre screened cable with
shielded RJ45 connections
Accessories
Connect in series with the network
cable, either:
a)
near to where it enters or
leaves the building, or
b) as it enters the network hub,
or
c)
close to the equipment being
protected
This should be close to the system’s
earth star point (to enable a good
connection to earth).
