ELECTRONICSYSTEMS PROTECTION

Plug-inLightning Barrier

WilfordRoad, Nottingham, NG2 1EB,UK

NEW

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 0Bto protect against flashover (typically the service entrance location) through to LPZ 3 to protect sensitive electronic equipment.

Installation

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,

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).

equipment

Features and benefits

✔ 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

Application

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

For further application information, see separate Application Note AN004 (contact us for a copy).

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.

The interfaces used in Cat-5/5e systems incorporate an isolation transformer that inherently provides an inbuilt immunity to transients between line and earth of 1,500 Volts or more.

Test to IEC 61000-4-5:2006, ITU-T (formerly CCITT) K.20, K.21 and K.45,Telcordia GR-1089-CORE, Issue 2:2002, ANSI TIA/EIA/IS-968-A:2002 (formerly FCC Part 68).

The first number is for the data pair, with the second number for the power pair.

The installation and connectors external to the protector may limit the capability of the protector.

To protect datacomms systems based on twisted pairs, use the ESP D, E or H Series. Local protection for networked equipment is also available. For protection of legacy coaxial Ethernet networks, please contact us for details of our ESP ThinNet and ESP ThickNet protectors.
