Is the shorting contactor and bypas contactor the same thing.
The shorting contactor and bypass contactor are not technically the same. While both may be connected at the same points on the softstart and once they are pulled in the internal electronics are bypassed on both. The bypass contactor when appropriately used as it is named should be rated for the full voltage start. You can obtain the appropriate shorting contactor by finding part number for unit in the instruction bulletin user`s manual.
