12/26 Total Solution to Earthing & Lightning Protection | 9AKK106354A3360
12
Combined Category D, C, B tested protector (to BS EN 61643) for ‘through hole’
mounting directly onto the PCB of data communication, signal or telephone
equipment which require a lower in-line resistance, an increased current or a
higher bandwidth than the PCB/**D Series. Available for working voltages of up
to 110 Volts for AC & DC power applications up to 125 Amps. For use at
boundaries up to LPZ 0 to protect against flashover (typically the service
entrance location) through to LPZ 3 to protect sensitive electronic equipment.

ESP PCB/E Series
Installation
Connect in series, soldering pins direct onto PCB. Tracks
to line and earth pins should be as wide as practical
(see Furse Application Note AN003). Dirty (line) tracks
should be routed parallel and as close together as possible.
This should also be implemented on clean tracks, however
clean tracks should never be routed close and parallel
to line tracks or dirty barrier earth connections as earth
connections as transients can be re-introduced after the
protector due to electromagnetic coupling.
The use of an earth layer or plane is highly recommended as
this reduces the electromagnetic field produced by a transient
discharging to earth considerably, and hence the chance of
the transient being picked up on clean tracks.
Full product range order codes can be found on pages 17/8-17/9
Maximum line to clean separation. Large input
tracks and pads (using top and bottom copper
layers). Earth pin is bonded to an earth layer/plane.
All dirty (line) incoming tracks are separated from the
clean output tracks, individual line and clean tracks
are routed close together. Earth pins are bonded to an
earth layer/plane.
