Type 1+2 AC surge protector - 1-pole

Part Number 3964
  • Type 1+2 unipolar AC surge protector
  • Iimp : 50 kA on 10/350µs impulse
  • Imax : 200 kA on 8/20µs impulse
  • Internal disconnecctions, status indicator and remote signaling
  • IEC 61643-11 and EN 61643-11

The DS500E is a SPD with a very high impulse discharge current (Iimp) of 50 kA, based on multi-varistor technology. A such high value could be required in the worse-case conditions (200 kA direct strike on installation equipped with single phase or 3-phase AC network).
