(3)After the leakage function (L) is selected, each protector is equipped with a leakage transformer.
The dimensions of the leakage transformer are shown in the section "overall dimensions and
installation". Leakage transformer is equipped with 2m
±
10cm secondary line as standard. If
you need other length, please contact the manufacturer.
