The V25 combination lightning and surge arrester (catalog number 5094510) Type 1+2 provides reliable protection against lightning currents and transient overvoltages. The 3+NPE configuration makes it suitable for TN and TT systems.
The device is supplied as a complete unit (plug-in module and base), pre-assembled and ready for connection. It includes remote signalling (FS variant) with a potential-free NO contact for function monitoring.
The maximum continuous operating voltage is 280 V AC. Nominal discharge current is 30 kA (8/20 µs), while the maximum discharge current reaches 150 kA. The voltage protection level is below 0.9 kV. Suitable for buildings with overhead supply lines and lightning protection equipotential bonding.
