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