DEHNvap

DVA CSP 1P 255 FM (900 368)

■ Prewired combined lightning current and surge arrester, energy-coordinated with power supply systems for cell sites (DEHNvap CSP ... CellSite Protection)

■ Maximum system availability due to follow current limiting RADAX Flow spark gap technology

■ Easy replacement of protection modules without tools due to module release button
