Surge Protective Devices With Low Voltage Protection Level

SPDs with low voltage protection level

  • To protect very sensitive electronic equipment.
  • The fine protection complements the main protection and can protect 1 or several electronic devices.
  • Optimal coordination is obtained when cascaded with a main protection device (lower Up see table below).
  • Protection is assured in both common and differential modes.

Discharge current :

  • I max. 8 kA (8/20 wave)

– A green LED on the front face indicates the status of the SPD connected in series with the equipment that needs to be protected.
– Connected in series with the equipment that needs to be protected.
– Suitable for every earthing system.

Connection capacity :

– 6mm2 flexible conductor
– 10mm2 rigid conductor

Degree of protection : IP 20 (in enclosure)

Complies with NF EN 61-643-11
