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
