Features:
Modular and plug-in arrestor.
Type 1+2+3 surge arrestor according to EN 61643-11.
Lightning current arresting capacity 12.5 kA (10/350us) per pole.
Operating state / fault indication by green / red indicator flag in the inspection window.
Remote signaling can be selectable.
Universally suitable for TT systems.
Application:
For general protection of big installations and protection of small installations with external lightning protection.
Installation:
Before installation, it should be check whether the surge protector is intact. If it is damaged or the display window is red, it cannot be used; if the window is green, it is normal.
