Furse Total Solution to Earthing & Lightning Protection

244 / 336

12/18 Total Solution to Earthing & Lightning Protection | 9AKK106354A3360
12
Combined Category D, C, B tested protector (to BS EN 61643) suitable for
3-wire signalling applications which require either a lower in-line resistance,
an increased current and/or higher bandwidth. Also suitable for DC power
applications less than 0.5 Amps. Available for working voltages of up to 6,
15, 30, 50 and 110 Volts. 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.
Data & signal protection
ESP SL 3-Wire Series
Installation
Connect in series with the data communication or signal line
either near where it enters or leaves the building or close to
the equipment being protected (e.g. within its control panel).
Either way, it must be very close to the system’s earth star
point. Install protectors either within an existing cabinet/
cubicle or in a separate enclosure.
Accessories
Replacement modules:

Features & benefits
–– 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
–– Ultra slim 7 mm width ideal for compact protection of large
numbers of lines (e.g. process control installations)
–– 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
–– Very low (1 Ω) in-line resistance allows resistance critical
applications (e.g. alarm loops) to be protected
–– High (500 mA) maximum running current
–– High bandwidth enables higher frequency (high traffic or
bit rate) data communications
–– Strong, flame retardant, polycarbonate housing
–– Built-in innovative DIN rail foot with locking feature for
simple positioning and clip-on mounting to top hat DIN rails
–– 4 mm2 terminals allow for larger cross section wiring,
stranded wires terminated with ferrules or fitting two wires
into a single terminal
–– Convenient earthing through DIN foot and/or earth terminal
Application
Use these protectors for 3-wire systems where installation
space is at a premium and large numbers of lines require
protection (e.g. process control, high speed digital
communication equipment or systems with long signal lines).
NOTE: The ESP SL ‘Slim Line’ Series is also available for protection of 2-wire systems up to 110 V, RS 485, RTD and telecommunication applications
(ESP SL Series, ESP SL RS485, ESP SL RTD and ESP SL TN). The ESP SL X Series has approvals for use in hazardous areas.
