Type 1 + 2 SPDs have characteristics of type 1 but also type 2, they are capable of discharging a very high lightning current (T1 10/350s) and they have as well a low residual voltage (Up). They are installed in the main distribution switchboard but also in subdistribution board. Because of their power, Type 1 + 2 SPDs can let pass through a too high residual voltage, if the announced Up is not compatible with the withstand voltage of the equipment to protect or if the cable length to the equipment is longer than 10m, another level of coordination with OVR T2- T3, OVR T3 will be needed. Thanks to the patented Safety Reserve system, you can extend the lifespan of the installation plan maintenance to reduce downtime risk. · · · Patented QuickSafe technology · · Safety Reserve system · · Din rail mounting · · Back up protection up to 160 A Fuse or 125 A Mcb · · Integrated thermal disconnector · · End of life indicator · · 4 Protected Lines · · Protection Mode L-N/L-PE/N-PE · · UpTo 1.1kV
