Lastnosti Characteristics
Odklopna naprava reagira: The disconnecting device reacts:
• ko v normalnem obratovanju tok skozi odvodnik • when in normal operation the current through the
naraste nad 1 mA, surge arrester increases over 1 mA,
• v primeru atmosferske praznitve • in case of an atmospheric discharge (current higher
(tok večji od 100 kA). than 100 kA).
Po delovanju odklopne naprave se vidno polje obarva After the disconnecting device has been active the visual

Prednosti pred konkurenco Competitive advantages

TY1-F odvodniki prenapetosti za notranjo montažo imajo TY1-F surge arresters for indoor installation have an
vgrajeno predvarovalko. Zato vgradnja predvarovalke integrated backup fuse. Therefore the installation of a
(glavna > 100 A) 100 AgL ni potrebna. backup fuse (if main > 100 A) 100 AgL is not necessary.

TY1 in TY1-F odvodniki prenapetosti za notranjo TY1 and TY1-F surge arresters for indoor installation
montažo imajo: have:
• ugodno ceno, • a favourable price,
• modularno ohišje, • a modular housing,
• zanesljivo delovanje. • reliable performance.
