The T1-25M/335-T3 is a 3-poles, single-bloc, very high-energy surge arrester designed to provide protection against both the direct (when a lightning conductor is present) and indirect effects of lightning. This device is intended for use in single-phase or three-phase networks in installations located in regions characterised by a very high lightning strike density.
