G E Testing
G E has developed a qualification test plan for the Power+™,
M icroVersoTrip Plus™ and M icroVersaTrip PM™ trip u n its that
is i n addition to the tests req uired by Standard UL 489. The
objective is to demonstrate performa nce and reliability under
severe operating conditions. Essential components of the
internal qualification test a re:
