Hi. This is probably more of a question to do with disambiguation. When talking about isolator switches and specifying for example 2pole or 4pole for a 3phase Isolator switch what does this mean?
For the 2pole example does it mean that each phase has 2 contactors for each phase ie A-A B-B C-C and that when turn the switch you disconnect each connection?? If so what is the 4 pole switch?
Many thanks!!
