FLP12.5-PV1500/3

FLP12.5-PV1500/3S

Modular multipole surge arrester for use in PV systems with remote signalling contact for monitoring device (floating changeover contact)

  • Prewired modular complete unit for use in photovoltaic systems consisting of a base part and plug-in protection modules
  • Combined disconnection and short-circuiting device with safe electrical isolation in the protection module prevents fire damage caused by d.c. switching arcs
  • Safe replacement of protection modules without arc formation due to integrated d.c. fuse
