Data & signal protection
ESP RTD, RTDQ & SL RTD Series
Installation
Connect in series with the signal line either near where it
enters or leaves the building or close to the equipment being
protected ensuring it is very close to the system’s earth star
point. Install protectors either within an existing cabinet/
cubicle or in a separate enclosure.

Features & benefits
–– Protects all three wires on a 3-wire RTD system with a
single protector
–– Very low let-through voltage (enhanced protection to
IEC/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
–– Low in-line resistance minimizes reductions in signal strength
–– Built-in DIN rail foot for simple mounting to top hat
DIN rails
–– Convenient earthing through DIN foot and/or earth terminal
–– ESP RTD can be flat mounted on base or side
–– ESP RTD and ESP RTDQ have colour coded terminals for
quick and easy installation check
–– ESP SL RTD has ultra slim 7 mm width ideal for compact
protection of large numbers of lines (e.g. process
control installations)
–– ESP SL RTD includes two stage removable protection
module with simple quick release mechanism
allowing partial removal for easy line commissioning
and maintenance as well as full removal for
protection replacement
For further information on RTD applications, see separate
Application Note AN001 (contact us for a copy).
NOTE:
For 2-wire or 4-wire RTD applications, use one or two ESP 06D or ESP SL06 protectors respectively.
Combined Category D, C, B tested protector (to BS EN 61643) suitable for
3-wire RTD systems to protect monitoring equipment. For use at boundaries
up to LPZ
0
(ESP RTD & ESP RTDQ) or LPZ
0
(ESP SL RTD) to protect
against flashover (typically the service entrance location) through to LPZ 3.
Available as standard ESP RTD format, or compact ESP RTDQ and
Slim Line ESP SL RTD versions for installations where a high number of
lines require protection.
