To compare the application of medium-voltage circuit breakers and of fused contactors, we must understand the basic characteristics of each switching technology. The below table shows the major characteristics of medium-voltage circuit breakers and medium-voltage fused contactors that influence the application. Of

In this method of inter-connection the similar ends either the ‘start’ or ‘finish’ are joined together at point N. This common point N is called star point or neutral point. Ordinarily only three wires are carried to the external circuit giving 3-phase,
