could someone please explain why the motor thermal protection setting on a ATV71 is set to 118%
where does this figure come from? if this is an allowance for service factor of the motor which i understood to be 115%
am i right in assuming that anything above 100% contributes to a shorter motor life?
is this the equivilent of other manufactures 100% setting (eg GE369 MM2 etc) who quote 100% thermal should be the trip?
