Data protectors DTNVEM 1/CIB
Surge guard device (SPD) according to ČSN EN 61643-21 (category A2,B2,C2,C3,D1)
designated for protection of system CIB against thunderstroke overvoltage.
Recommended position is by the start of conduction coming from outside into the
building, then on the edge of other LPZ ( according to EN 62305) and near to protected
device. The lenght between protector and protected device can not be more than
10meters.
DTNVEM 1/CIB is constructed form the base and the changeable module, which
contains its own protection. Base is permanently connected and in the case of revision
or demage, there is manipulation only with changeable module. Base is through-transit
also without changeable module (circuit is on).
Protection is designated for permanent current max.0,5A. Already during the projecting
of aplication is neccessary to secure this max. limit.
