SPECIFICATIONS
l SPD according to EN 61643-11/IEC 61643-11: Type 2 / Class Ⅱ
l Nominal voltage (a.c.) (Un): 230/275/385/420V (50/60Hz)
l Max. continuous operating voltage (a.c.) (Uc): 275/385/420V (50/60Hz)
l Nominal discharge current (8/20µs) (In): 10kA/ 20kA/ 30kA
l Max. discharge current (8/20µs) (Imax): 20kA/ 40kA/ 60kA
Maximum discharge current Imax The maximum discharge current Imax is defined according to the estimated exposure level relative to the building’s location. The value of the maximum discharge current (Imax) is determined by a risk analysis (see table in Figure 1). Fig. 1 – Recommended maximum discharge current Imax according to the exposure level Exposure […]
