On an 8910DPA contactor, what does the footnote in Digest 175, page 16-76 mean: ``Above 240V, all lines must be switched``?

This instruction means that all three phase lines on a three phase system must run through the contactor power poles. No unswitched lines are permitted to run to the motor or load directly. Failure to do this will shorten the life of the contactor.
