ESP WT Series

The ESP WT Series is a combined Type 1 and 2 tested protector (to BS EN 61643) for use on the main distribution board within wind turbines, for equipotential bonding.

For use at boundaries up to LPZ 0 to protect against flashover (typically the main distribution board location) through to LPZ 2 to protect electrical equipment from damage.

Features & benefits

  • Enhanced protection (to IEC/BS EN 62305) offering low let-through voltage further minimizing the risk of flashover creating dangerous sparking or electric shock
  • Repeated protection in lightning intense environments
  • The varistor based design eliminates the high follow current (If) associated with spark gap based surge protection
  • Indicator shows when the protector requires replacement
  • Remote signal contact can indicate the protector’s status through interfacing with a building management system
