241203_EP_12V_20A_LED_v02.jpg
Two-pole SPD for operating current up to 20 A in looped-in wiring, with disconnection device without interruption of the power supply. A very low protection level allows the use as SPD type 3 (class III).
  • SPD type 2 for DC power supplies
  • Surge voltage protection for electrical and electronical devices
  • Arrester status control display: LED green (readiness: on)
  • With low-pass filter
  • EAC certification
