Total Solution to Earthing & Lightning Protection |
9AKK106354A3360
12
Combined Category D, C, B tested protector (to BS EN 61643) suitable for twisted
pair 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 0.75 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 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:
ESP SLXX/M
Standard module replacement where XX is
voltage rating (06, 15, 30, 50 or 110)
ESP SLXXL/M
LED module replacement where XX is
voltage rating, as above
ESP SL/B
Base replacement (common for standard
and LED modules)
ESP SL/I/B
Base replacement with isolated
screen from earth

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)
–– Optional LED status indication versions available for
low current DC power applications - add L suffix to part
number - e.g. ESP SL30L
–– 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
–– Strong, flame retardant, polycarbonate housing
–– High (750 mA) maximum running current
–– High bandwidth enables higher frequency (high traffic or bit
rate) data communications
–– Screen terminal enables easy connection of cable screen
to earth
–– Suitable for earthed or isolated screen systems - add /I
suffix to part number for versions that require isolated
screens - e.g. ESP SL30/I
–– Built-in innovative DIN rail foot with locking feature for
simple positioning and clip-on mounting to top hat DIN rails
–– 4 mm
2
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
–– Very low (1 Ω) in-line resistance allows resistance critical
applications (e.g. alarm loops) to be protected
Application
Use these protectors 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 3-wire, RS 485 and RTD applications (ESP SL/3W, ESP SL RS485 & ESP SL RTD).
The ESP SL X Series has approvals for use in hazardous areas.
