SPECIAL THREE PHASE MAGNETIC MOTOR STARTER FOR
OPERATION FROM 575 VOLT THREE PHASE POWER SYSTEMS
Fig. 9, illustrates the special LVC starter which has
been designed for use exclusively on 575 volt, three
phase power systems.
The only difference between the 575 volt three phase
LVC starter and the standard three phase starter,
shown in Fig. 13, is the control transformer.
The instructions for connecting the power supply to
the special 575 volt starter are identical to the in-
s t r u c t i o n s f o r c o n n e c t i n g t h e p o w e r s u p p l y t o t h e
standard three phase motor starter. See instructions
for connecting the power supply to the three phase
motor starter on page 15.
The control transformer in the standard three phase
starter, shown in Fig. 13, has a multi-tapped primary
which enables the starter to be used from either a
115, 200, 230, 400 or 460 volt three phase power
system. In the special 575 volt three phase starter,
