ESP DT1 Series (Three Phase)

The ESP DT1 Series is a combined Type 1, 2 and 3 tested protector (to BS EN 61643) for use on 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 0 to protect against flashover (typically the main distribution board location, with multiple metallic services entering) through to LPZ 3 to protect sensitive electronic equipment.

Features & benefits

  • Very low let-through voltage (enhanced protection to IEC/BS EN 62305) between phase and neutral conductors, where sensitive equipment is connected
  • Full Mode design capable of handling partial lightning currents as well as allowing continual operation of protected equipment
  • Repeated protection in lightning intense environments
  • 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
