Does setting up a Micrologic for 3p 3w cause it to ignore the neutral if one is connected? And if so, does it apply to metering, protection, or both?In other words, what is the difference for metering and protection for setting a trip unit up for 3p 3w vs 3p 4w?

Micrologice Solid State types

Application on 3w system

Setting for 3p3w will cause both metering and protection functions to ignore any input from the neutral CT if present. 3p4w will check for neutral CT input and factor it into GF calculations.
