Lightning current and surge arrestor, 3-pole + NPE with remote signalling

V 50-B+C/3+NPE+FS: combination arrestor set, lightning and surge arrestor type 1+2 to DIN EN 61643-11 (B+C to VDE 0675 part 6).

• For lightning current equipotential bonding to VDE 0185-305 (IEC 62305)
• Lightning current dissipation capacity 12.5 kA (10/350) per pole
• Universally suitable for TN and TT systems
• With new Multibase base with multiple connection terminals
• Complete unit, consisting of cover and base, pre-mounted and ready for connection
• arrestor, connectable with dynamic cut-off unit
• With optical function display
• Voltage protection level • Encapsulated, non-extinguishing zinc oxide varistor arrestor for use in distributor housing
• Labelled connections
• -FS variant with remote signalling contact (potential-free NO contact)

Application: lightning protection equipotential bonding in buildings which also have external lightning protection of Classes III and IV and in standard distributor housings.
