Standard Applications – Electrical equipments Protection – SPD

The VP range of products protect electrical equipment and installations against transient overvoltage that may arise in the electrical supply. Besides, the VP range can be classified into 3 different types (C, B, B+C) which provide the highest protection level in order to prevent damages in the electrical equipment and financial losses.

  • Compact equipments for all distribution systems
  • High discharge capacity via zinc oxide varistors and gas deschargers
  • With thermal separation device
  • Visual indication of a fault in the equipment
  • Remote signalling of the protection status
  • Plug-in protection modules which facilitate maintenance
