Product description

Product description

Lightning arrester, type 1

• Voltage protection level < 1.3 kV, allows device protection
• For lightning protection equipotential bonding to VDE 0185-305 (IEC 62305)
• Lightning current arresting capacity to 50 kA (10/350) per pole and up to 150 kA (10/350) in total
• Line following current quenching 25 kA Ipeak, arrester backup fuse to 500 A gL/gG
• Encapsulated, non-extinguishing spark gap arrester for use in distributor housings

Application: Industrial systems and buildings with external lightning protection of the classes I to IV.
