7P SERIES
Surge Protection Device (SPD)
SPD Type 2+3 with combination of coarse and
fine suppression for 2 wires telecomunication
and signalling network
Suitable for the protection of 2 wires data lines
and telecommunication interface allowing
continuity of the shield
Permits serial connection optimizing the fine
protection of longitudinal overvoltage
(core-PG) and lateral overvoltage (core-core)
Conform to EN61643-21+A1,A2:2013,
