1 Line Current rating In-line resistance Nottingham, NG EB, UK 0V 6.7V 750mA.0Ω 0kA 6V ESP SL Series Combined Category D, C, B tested protector (to BS EN 66) 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, 5, 0, 50 and 0 Volts. For use at boundaries up to LPZ 0 B to protect against flashover (typically the service entrance location) through to LPZ to protect sensitive electronic equipment. Features and benefits Very low let-through voltage (enhanced protection to BS EN 605) 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 SL0L 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 ( 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 SL0/I 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 mm 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 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).

The devices and wiring produce a voltage drop (also known as loop drops ) but these do not reduce the -0 ma current as long as the power supply voltage is greater than the sum of the voltage drops around the loop at the maximum signalling current of 0 ma. For design considerations, each ESP SL0L/-0 device installed within the loop introduces a.7 V loop drop.
