Combined Arrester DEHNshield Type 1+2 Three-Phase TN-C TNC 255 - 941300
The Dehn DEHNshield combined arrester is designed for energy technology, featuring a TN-C network structure with 3 poles. With a surge current of 37.5kA during storms, it operates at a maximum continuous voltage of 255V AC, with a nominal voltage of 230V AC. It features safety levels of 1.5kV for both L-N and L-PE and has a follow current extinguishing capacity of 25kA. This compact device uses space-saving spark-gap technology for a one module per pole design, optimized for applications in residential buildings and special equipment. It provides protection against surges for low-voltage consumer installations, even during direct lightning strikes and conforms to lightning protection zone boundaries from 0A – 2, according to EN 61643-11 standards.
