Protection for 4 twisted pair lines (ESP 06Q, ESP 15Q, ESP 30Q, ESP 50Q
and ESP TNQ).
Protection for three 3-wire
RTD lines (ESP RTDQ).
Available for working
voltages of up to 6, 15, 30 and 50 volts, and telephone lines with a maximum
working or ringing voltage of 190 volts.
Protectors for individual data
and signal lines are the ESP D series, or ready-boxed
to IP66 the ESP D/BX series. Alternatively,
for individual protectors with higher current or bandwidth see the ESP
E series. For individual 3-wire RTD applications see the ESP
RTD
Application
Use these protectors where installation space is at
a premium and large numbers of lines require protection. Typically used
in process and petrochemical applications to protect supervisory, control
and data acquisition systems.
ESP 30Qs mounted on a G DIN rail, protect 48
twisted pair lines.
Features and benefits
 Protect
four twisted pair lines (plus screens) in one compact unit (ESP 06Q, ESP
15Q, ESP 30Q, ESP 50Q and ESP TNQ).
ESP
RTDQ protects three 3-wire lines in RTD applications.
Almost
twice as space efficient as smallest competitor .
Standared
DIN module (18mm) depth.
Removable
(plug-in) terminals allow pre-wiring of cable looms for easier installation.
Built-in
DIN rail foot for clip-on mounting to top hat or G DIN rails.
Optional
flat mounting on side.
The Q series can be earthed via DIN rail or
via the M3 threaded hole in the base (shown here).
2.5mm2
terminals allow for larger cross section wiring, stranded wires terminated
with ferrules or fitting two wires into a single terminal.
Low
let-through voltage between all line.

Very
low resistance to minimise unwanted signal strength reductions.
Strong,
flame retardant, ABS housing.
Colour
coded terminals (grey for line, green for clean) give a quick and easy
installation check.
Screen
terminal enables easy connection of cable screen to earth.
Simple,

Approval NS/G/1235/W/100025.
A Q Series protector mounted on a top hat DIN
rail. Note the plug-in terminals for easier installation in confined
spaces.
Installation
Connect in series with the signal or data line either
near where it enters or leaves the building or close to the equipment
being protected. Install in a cabinet/cubicle close to the systems earth
star point.
