Cudis SPD-3PNEC2 3 Phase 3Pole and N Surge Module Class II SPD with TT Earthing
DIN rail AC Surge Protective Devices (SPD’s) are connected in parallel and use an MOV to clamp high-voltage surges. These devices are primarily used in the main electrical panel for the protection of single and three phase systems.
The SPD-C2 range meets the type 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 protection level. If there is a risk of fire from an overload, the internal cut-out unit disconnects the device from the mains if necessary.
