The ESP 240-16A/BX is a combined type 2 and 3 tested protector (to BS EN 61643) for use on low current (up to 5 or 16 A) single-phase systems to protect connected electronic equipment from transient overvoltages on the mains supply, e.g., fire/intruder alarm panels.

For use at boundaries LPZ 1 through to LPZ 3 to protect sensitive electronic equipment.

Features & Benefits

  • Very low let-through voltage (enhanced protection to IEC/BS EN 62305) between all sets of conductors (phase to neutral, phase to earth, neutral to earth – Full Mode protection), allowing continuous operation of equipment.
  • Compact size for easy incorporation in the protected system.
  • Removable DIN rail foot for simple clip-on mounting to top hat DIN rails (unboxed versions).
  • Colour-coded terminals give a quick and easy installation check – grey for the dirty (line) end and green for the clean end.
  • Available ready-boxed to IP66 for use in dirty or damp environments (protectors with /BX suffix).
  • Robust housing and substantial earth stud fixing holes ready for flat mounting.
  • Maintenance free.

Application

Use these protectors on low-current mains power supplies, e.g. CCTV cameras, alarm panels and telemetry equipment.

Installation

Connect in line with the power supply, usually either within the equipment panel (or, for CCTV cameras, in an enclosure close by) or on the fused connection that supplies equipment.

To protect equipment inside a building from transients entering on an outgoing feed (e.g. to CCTV cameras or to site lighting), the protector should be installed as close to where the cable leaves the building as possible.

Unless ready-boxed, protectors should be installed either within an existing cabinet or cubicle or in a separate enclosure.
