is
an

the

digits
of
their
designation
as
in
the
following
example
:

.
Some
installations
require
that
breakers
serving
essential
circuits be
segregated
from
identical
models
deployed
else
-
where
in
the
power
system
.
The
segregation
is
physical
and is
accomplished
by
supplemental
rejection
hardware added
to
the breaker
and
its
drawout
compartment
.
In
this
publication
these
special
