-Otc=Def/Inv:dt+0.1sec if starting current
exceeds 300% to oc during dt, Lc is shown in
trip
*In case Load is selected ,this protection is done by
imaginary oc value calculated internally by the
relationship of V,I,PF,Effeciency.

*If KW is selected, the imaginary "OC" value
such as a case of "Lc" is adopted to execute short
protection
*OFF:this mode is disable
*Available current range for 70 type is 0.2A~
10A ,so if the current over 10A for “OC”
protection value is preset, this mode is displayed
like “SS—“”
