Paul, The datasheet does not show any info about short term current limit versus long term, but rest assured that at that voltage you will never draw 600A very long and the average current draw will be closer to 50 Amps so there is plenty opportunity for the contactors to cool down if you ever did a long steep hill climb at maximum throttle for whatever reason. My S10 also has a 360V pack and on flat road doing 55 the draw is 40 Amps continuous. No, the max current is unlikely to be the cause of the fails. More likely a failing or insufficient pre-charge.
