Product description

Product description

Combination arrester, lightning and surge arrester type 1+2 to DIN EN 61643-11.

• For lightning protection equipotential bonding to VDE 0185-305 (IEC 62305)
• Lightning current arresting capacity 12.5 kA (10/350) per pole and 50 kA (10/350) in total
• Universally suitable for TN and TT systems
• With new Multibase base with multi-connection terminals
• Complete unit, consisting of upper part and base, pre-mounted and ready for connection
• Arrester, connectable with dynamic cut-off unit
• With visual function display
• Protection level < 1.3 kV
• Encapsulated, non-extinguishing zinc oxide varistor arrester for use in distributor housings
• Labelled connections

Application: Equipotential bonding in buildings, even those with external lightning protection of the Classes III and IV, and in standard distributor housings.
* Complete = Plug-in arrester and base
