Cudis SPD-3PNEC1+2 3Phase 4 Module Type 1+2 Surge Device SPD with TT Earthing
Class I+II surge protection devices (Type 1+2 surge protectors) are designed by combining Class I (10/350µs) and Class II (8/20µs) lightning and switching surge to be used in the equipotential connection of LPZ 0 and LPZ 2 zone.
Class I+II surge protectors work as a complete protection device and are perfect for any kind of building be it residential, commercial or industrial. In addition, you can install transient voltage surge arresters in buildings that are powered directly via overhead power lines.
The combination lightning current and surge (SPD-C1+2 Range) meet the type 1+2 requirement class according to IEC 61643-11. These devices protect low-voltage consumer systems from overvoltages of all types and are available in single-pole to four-pole versions. The use of high-performance varistors permits a rapid response time and a low voltage protection level, without any line follow current. If there is a risk of fire from an overload, the internal cut-out unit disconnects the device from the mains if necessary.
