ESP SL X Series
NEW
Approved for use in hazardous environments for the protection of
Intrinsically Safe circuits (Classification: II 2(1)G, Ex ia (ia Ga) IIC T4 Gb)
Very low let-through voltage (enhanced protection to 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 SL30XL
Negligible self-capacitance and self-inductance offering minimal
interference when protecting Intrinsically Safe circuits
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 (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 SL30X/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
Approval references for ESP SL X Series: IECEx SIR 10.0030X,
Sira 10ATEX2063X
Features and benefits
Combined Category D, C, B tested protector (to BS EN 61643)
suitable for twisted pair signalling applications within hazardous
environments (ATEX/IECEx approved). Available for working
voltages of up to 15 and 30 Volts. For use at boundaries up to LPZ
0
B
to protect against flashover through to LPZ 3 to protect sensitive
electronic equipment.
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.
Installation
Use these protectors in hazardous
environments where installation
space is at a premium and large
numbers of lines require
protection (e.g. process control,
4-20 mA loops, fire and gas
detectors and shut-down systems).
Suitable for high speed digital
communication equipment or
systems with long signal lines. See
