ESP BESS DC Series

The ESP BESS DC Series is a Type 2 (plus Type 1) tested Surge Protective Device (SPD) for DC Battery Energy Storage Systems (BESS).

For use at the DC side of the AC/DC converter located within Lightning Protection Zone 1 (LPZ 1) to protect the BESS system from surge damage due to lightning and electrical switching events. 

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 - with Type 1 high energy surge capability
  • The varistor based design eliminates the high follow current (If) associated with spark gap based surge protection
  • Pluggable module design (with anti-vibration locking clip) allows for simple replacement at end-of-life
  • Compact, space saving design
  • Indicator shows when the SPD requires replacement
  • Remote signal contact, with fast fit screw-less push terminals, can indicate the SPD's status through interfacing with a building management system
