There are basically two standards for AC input power supply worldwide That is 230V in some parts of the world and 110V in some other parts 2 1/8V is for a 110V system basically with 1V as L to N and 8V as L to L Similarly, for 277/480V, 277 is L to N and 480V is L to L (V L to L = V L to N)1/8V is the standard 3 phase voltage 230 volt motors were run on 8 volts for years but it is becoming more common to use 0 volt rated motors on 8 volt systems 1/240V is the standard single phase system voltage 230 Volts, where to start 230 volts is a valid motor voltageThe question asks about substitution This is the process of confirming the suitability of one product for another In this case it is about electricl compnents, and the suitabilty of a 2pole circuit breaker, to function in a 3phase panel So, I
