Description

DIN-EN 60715 TH35 DIN rail mounting device.
TÜV-certified according to IEC 61643-11, certificate number: AT 50567910 0001.
4 division units = 72 mm wide.
The modular combination conductor reliably protects electrical systems against transient overvoltage.
Provides high protection in direct lightning in TT-, TN-C- and TN-S-systems. 12.5 kA Shock resistance
Per pin Simple DIN rail mounting and modular design allow quick installation and maintenance.
The protection classes type 1+2+3 are combined in one device and thus make possible a comprehensive surge protection from the entry of building to the end device.
The use of a MUA-50 combination conductor is mandatory in accordance with DIN VDE 0100-443/534 for new buildings as well as for expansions with powerful consumers (e.g. Wallbox, heat pump, PV-system).

If external lightning protection is provided, a protection level is required:
Type 1 in the main distribution (e.g. MUA-100, MUA-50)
Type 2 in the sub-distribution (e.g. MUA-30, MUA-20)
A type 2 arrester in the sub-distribution is only required if the cable length to the main distribution with installed type 1+2+3 is more than 10 meters.
