Two-Stage CTs:
Two-stage CTs are used on systems that have primary voltages in excess of 600 VAC or line
currents higher than 936 amps. The first-stage CT part numbers are in the X-13580047 and X-
13580048 families. The second stage is a custom current transformer (X-13580266-01) which
has a transformation ratio of 3.6A:0.1A. The secondary of this transformer is then applied to the
Starter module.
