one shot at three-phase auto reclosing".

ARMode = 1ph + 1*2/3ph, 1-phase, 2-phase or 3-phase reclosing in

the first shot

At single-phase or two-phase tripping, the operation is as in the above described

example, program mode 1/2/3ph. If the first reclosing shot fails, a three-phase trip

will be issued and three-phase reclosing will follow, if selected. At two-phase or

three-phase trip a failure of a two-phase or three-phase auto reclosing attempt will

inhibit the auto recloser. No more shots are attempted. The expression "1*2/3ph"

should be understood as "Only one shot at two-phase or three-phase auto
