Caratteristiche:
Surge arrestor.
Meet the type 1+2 requirement class according to IEC 61643-11.
High arresting capacity up to 12.5 kA (10/350μs).
Visual status display.
The use of high-performance varistors permits a rapid response time and a low protection level, without any line follow current.
Available with optional remote signaling.
Simple standard Din rail mounting.
Labeled connections.
Uc: 150v, 275v, 320v.
Based on high energy Metal Oxide Varistors.
Versions with 1P, 1+NPE, 2P, 3P, 3+NPE and 4P.
Exclusive devices for TN-S, TN-C and TT systems.
Reversible chassis to allow cable entry from above or below.
Indoor fixed installation, voltage limited type.
Module design.
Large lightning current discharge capacity.
Easy to maintain.
When the SPD works normally, the visible window displays green, and when it fails, it displays red.
Time of response<25ns.
Could supply different working voltage level and lightning discharge current, also could customized according to different requirement.
Applicazione:
Usable in systems with lightning protection class 1+2.
Installazione:
Please connect according to the installation diagram; the connecting wires must meet the requirements.
When the failure display window of the module indicates red, it means that the lightning protection device has failed, and new products should be replaced in time.
