Furse ESP SL Series


Combined Category D, C, B tested protector (to BS EN 61643-21) 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 0B to protect against flashover (typically the service entrance location) through to LPZ 3 to protect sensitive electronic equipment.

Features and Benefits

  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 7mm 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�) in-line resistance allows resistance critical applications (e.g. alarm loops) to be protected
  High (750mA) 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
  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
  4mm2 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).

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 systems earth star point. Install protectors either within an existing cabinet/cubicle or in a separate enclosure.

Accessories

Replacement modules:

ESP SLXX/M - Module replacement where XX is voltage rating (06, 15, 30, 50 and 110)

ESP SL/B - Base replacement

ESP SL/I/B - Base replacement with isolated screen from earth
