Varistor in parallel:

When a TGE mov varistor for counter nominal discharge current can not meet the requirements, it should be used in parallel with multiple varistors. Sometimes in order to reduce the limit voltage, even if the nominal discharge current to meet the requirements adopted
A plurality of mov metal oxide varistor in parallel. Pay particular attention to that when the TGE metal oxide varistor theory in parallel, must be consistent with carefully selected parameters (for example: ΔU1mA≤3V, Δα≤3) paired to
