Notes
I If the maximum loads specified for load dump and jump start are fully utilized, subsequent
polarity reversal of the AUTO varistors is inadmissible.
I If the load remains under the maximum ratings, polarity reversal may be admissible.Contact EPCOS for consultancy on this kind of problem.
I Load dump or jump start can decrease the varistor voltage in load direction by max. 15 %.I Load dump: min. time of energy input 40ms, interval 60 s.
