ESP CD40 Series

The ESP CD40 Series is a compact combined Type 2 and 3 tested (to IEC/BS EN 61643) Surge Protective Device (SPD) for use on single and three phase mains power distribution systems primarily to protect connected electronic equipment from transient overvoltages on the mains supply, e.g. computer, communications or control equipment.

For use at boundaries up to 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)
  • All mode design for continual operation of protected equipment
  • Repeated protection in lightning intense environments
  • SPD includes hybrid combination of MOVs and GDTs
  • Innovative multiple thermal disconnect technology for safe disconnection from faulty or abnormal supplies (without compromising protective performance)
  • Three way visual indication of protection status and advanced pre-failure warning so you need never be unprotected
  • Remote indication facility allows pre-failure warning to be linked to a building management system, buzzer or light
  • Changeover active volt-free contact enables the protector to be used to warn of phase loss (i.e. power failure, blown fuses, etc)
  • Flashing warning of supply faults leading to increased neutral to earth voltage (supply faults due to incorrect earthing, wiring errors or unbalanced conditions) - prevents potentially unsafe installations
  • Compact space saving DIN housing with DIN release and locking feature for easy positioning onto DIN rail
  • Large, robust terminals for straightforward connection of conductors
  • Innovative design delivers zero leakage current to earth, so is suitable for TT and TN earthing systems
