Furse Earthing and Lightning Protection
and Electronic Systems Protection by Thomas & Betts
Enhanced Single Phase
Supplies for Equipotential Bonding
 Use
on single phase mains supplies and power distribution systems
for protection against partial direct or indirect lightning
strikes.
-
Enhanced
protection (to BS EN 62305) offering low let-through voltage
further minimizing the risk of flashover creating dangerous
sparking or electric shock
-
Repeated
protection in lightning intense environments
-
The varistor
based design eliminates the high follow current (lf)
associated with spark gap based surge protection
-
Indicator shows
when the protector requires replacement
-
Remote signal
contact can indicate the protectors' status through
interfacing with a building management system
-
Compact, space
saving design

Single Phase Supplies with
DIN Housing
 Combined
Type 1, 2 and 3 tested protector (to BS EN 61643) for use on
mains power distribution systems primarily to protect connected
electronic equipment from transient overvoltages on the mains
supply, e.g. computer, communications or control equipment.
Innovative remote display options allow both protector and
display to be mounted in their optimum position.
-
Very low
let-through voltage (enhanced protection to BS EN 62305)
between all sets of conductors (phase to neutral, phase to
earth, neutral to earth - Full Mode protection)
-
Full mode design
capable of handling partial lightning currents as well as
allowing continual operation of protected equipment
-
Three phase ESP
XXX D1R/LED or ESP XXX D1R/LCD units (where XXX = 208, or
415, or 480) have a remote display that allows the protector
to be mounted close to the incoming feed or distribution
board with the display being mounted in a visible position
e.g. at the front of the panel
-
Three phase ESP
XXX D1/LCD or ESP XXX D1R/LCD units have backlit LCD
intelligent display offering clear status information that
can be rotated should the unit be mounted on its side to
facilitate short connection leads for optimal protection
-
Changeover
active volt free contact enables the protector to be used to
warn of phase loss (i.e. power failure,
blown fuses etc)
-
Flashing warning
of potentially fatal neutral to earth supply faults (due to
incorrect earthing, wiring errors or unbalanced conditions)

fitted.
-
Very low let-through voltage
between all sets of conductors (phase to neutral, phase to
earth and neutral to earth)
-
Full mode design capable of
handling high energy partial lightning currents as well as
allowing continual operation of protected equipment
-
Innovative multiple thermal
disconnect technology, for safe disconnection from faulty or
abnormal supplies (without compromising protective
performance)
-
Three way visual indication of
protection status
-
Advanced pre-failure warning so
you need never be unprotected
-
Remote indication facility
allows pre-failure warning to be linked to a building
management system, buzzer or light
