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.
