Surge arresters – ETITEC
ETITEC surge arresters are intended for protection of electrical installations and devices against overvoltage effects, which may occur in atmospheric discharges and switching overvoltages. The main part of surge arrester is ZnO non–linear varistor. Its main characteristic is ohmic nonlinearity, which depends strongly on the applied voltage at the clamps. All arresters have modular construction, a special feature is interchanging varistor part and visual signalization for varistor thermical failure. The signalization performed with a red flag, which appears when failure occurs. The models with RC mark are equipped with auxiliary contacts for signalization.ETI also provides SPD protection for PV systems - see Green Protect catalogue.

ETITEC B is surge arrester for indoor application. Group B overvoltage protection is in accord-ance with VDE class B, C. This protection corresponds to IEC category I, II. The protection is made on the main distribution box, as the first level of protection against lightning strikes, partial direct, indirect atmospheric discharges and induced surges. In case of permanent arrestor damage, thermal protection is activated which signalizes faulty arrester. Conse-quently only the varistor overvoltage insert has to be replaced. The basic casing remains in the top hat fixing DIN rail. ETITEC B 230/100G is an overvoltage arrester for protection against partial direct and indirect atmospheric discharges. It is used as a galvanic separation between N-PE conductor in TT systems.
Advantages:n indication window of faulty device
n two module system (in case of a failure of one of the modules protection is still possible)
n remote signalisation
n mounting on DIN rail
n connection up to 35mm2
n high discharge currents
n high degree of protection
n varistor is the protective element
