SPD Type 1+2+3 - CT Series

Combined surge arrester with rare-gas-filled spark gap and very low protec-tion level < 1.0 kV for the use in three-phase TT, TNC and TNS systems. They provide extremely high discharge cappabilities with at the same time very low protection levels and they also do not need any damageable internal or external electronic trigger.
