The current transformer must be pur-
chased separately. See Appendix for
Watlow current transformer part
numbers.
Systems that use more than 50 Amps
need an interstage transformer. For
example, if you use a 300A current
transformer, part #16-0073, and an
interstage transformer, part #16-
0176, the 300A current transformer
provides a 5A signal to the interstage
transformer. In turn, the transformer
sends a 20mA maximum signal to the
controller.
