Notes
■If the maximum loads specified for load dump and jump start are fully utilized, subsequent
polarity reversal of the AUTO varistors are 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.
