The SPD range FLP-25-T1-V is supplemented with products  (FLP-25-T1-V(S)/1, FLP-25-T1-V(S)/2, FLP-25-T1-V(S)/1+1) suitable for single-phase connections of TN-C (TN-C-S), TN-S, and TT supply systems for nominal voltage 230 V AC.These products have a robust construction, do not generate the follow current, do not leak out the leakage current, and have a low residual voltage for proper coordination with other SPDs. More detailed information may be found in our on-line catalogue.
