Kumwell Surge Protection Device (SPD) provides protection against electromagnetic impulses
from lightning to the electrical and electronic equipment located on the structures. Although
surges have existed since the creation of electrical network, the need for protection is nowadays
much greater. This is due to advanced technology making electrical component ever smaller
and more sensitive to electromagnetic disturbances.
Kumwell SPD has tested according to IEC 61643-11, IEC 61643-21, IEC 61643-31 and certified by
VDE (Verband der Elektro technik). Moreover, we provide the new technology of Smart SPD
Monitoring for maintain the reliability of SPD in the system
