ABB TU516 1SAP212000R0001 New Board

Function U can be used in those cases where a particularly accurate control is needed as regards phase lack/unbalance. This protection intervenes if the r.m.s. value of one or two currents drop below the level equal to 0.4 times the current I1 set for protection L and remain below it for longer than 4 seconds. This protection can be excluded.
