Special Circuit Breakers: DS-206S and DS-416S
Table 1 gives the interrupting rating of DS-2068 as
42,000 amperes at 600 volts
AC.
It is an improved model
of DS-206, which has an interrupting capacity of 30,000
amperes at 600 volts
AC.
Yet,
the maximum continuous
current rating of 800 amperes is the same for both types.
Also, their parts are similar except for these differences:
1.
D8-2068 uses the three piece base of the
08-416
type, instead of the one piece molded base of the
DS-206.
2.
D8-2068 uses the D8-416 arc chute.
3.
D8-2068 main disconnects have 50% more fingers
than the 08-206.

4.
D8-206S has twice as many main contacts and arms
as the D8-206.
5.
The pole unit hinge joint of D8-2068 is a forked con-
struction or a miniature version of the
08-416
hinge.
6.
Fifty ampere sensors cannot be installed on
D8-206S; but they can be put on DS-206.
Similarly, the parts of D8-4168 are almost identical to
those of D8-420. Their interrupting ratings are the same:
65,000 amperes at 480 volts AC and 50,000 amperes
at
600 volts
AC.
But, the maximum continuous current rat-
ing of
08-420
is 2,000 amperes and for D8-416S it is
1600 amperes.
Compared to Type D8-416, D8-4168 has higher inter-
rupting ratings, giving it improved operating flexibility. See
Table 1.
