ESP SLX Series

The ESP SLX Series is a 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 to protect against flashover through to LPZ 3 to protect sensitive electronic equipment.

Features & benefits

  • 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 IEC/BS EN 62305) between all lines
  • 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
  • Negligible self-capacitance and self-inductance offering minimal interference when protecting intrinsically safe circuits
  • 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
  • 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
  • Approval references for ESP SL X Series: IECEx SIR 10.0030X, Sira 10ATEX2063X
  • Evaluated for SIL to IEC 61508
