Type 1 surge protective device
Modular type 1 surge protective device – Iimp 25kA – 3P+N
Modular protections 25 kA (10/350)
Networks 385V – Applications level I
Test standards : EN 61643-11
Description
Test standards : EN 61643-11
Based on varistors and very high energy encapsulated spark gaps, these surge protective devices are designed for protecting the inputs of main power supplies for highly exposed sites. Their flow capacities are much higher than the minimum requirements of NF C 15 100 and IEC 60364 electrical standards (sites equipped with lightning rods : protection of network’s inputs with 12,5 kA/type 1 surge protective device).
Products equipped with end of life indicators and terminals for remote monitoring. Mounting on symmetrical DIN rail foot (EN 50022).Applications types : Main boards of main and secondary buildings.
Recommended for TT / TN-S networks.
