Surge arrester Type 2 requirement class C, UC:350V, Pluggable protective modules 3-pole, 3+0 circuit for TNC systems.
Surge arrester Type 2 requirement class C, UC:350V, Pluggable protective modules 3-pole, 3+0 circuit for TNC systems.
Due to the combination of three power varistors, the overvoltage protection required for the inverters is implemented on the DC side. On the AC side, the overvoltage protection can be ensured using surge arresters type 2 (5SD7422-/5SD7424-)
