T1-12.5M/335-T2 surge arresters offer complete protection for installations, protecting them from both the direct (when a lightning protector is present) and indirect effects of lightning. They are specially designed to be deployed on single-phase or three-phase networks located in areas characterised by extremely high lightning strike density.
