Catalog excerpts
Surge Protective Device for Low-voltage Power System ♦ Consisting of a base part and MOV pluggable protection modules. ♦ For using in the lightning protection zones concept at boundary 1-2. ♦ The core parts are metal oxide vristor components with high discharge capacity. ♦ Low residual voltage and quick response. ♦ Reliable control thanks to Thermo Dynamic Control disconnector. ♦ With remote signaling contact for control device. ♦ Fault indication via red mark in the inspection window. ♦ Protection mode: L1,L2,L3,N-PE. Remark: if the model number is without“S”, the model is without remote control contact function
