Interference Interlocks
On original equipment, interference interlocks are sup-
plied
on breakers and in compartments where the com-
partments are
of the same physical size, to insure that a
Type DS-206 breaker cannot be inserted into a compart-
ment intended for a Type DS-416 or DS-420 breaker, and
a Type DS-416 or DS-420 breaker cannot be inserted into
a compartment for a Type DS-206 breaker.
It is impor-
tant that when equipping any blank breaker cell that
proper installation
of the correct interference brackets be
followed.
When ordering complete parts for blank cells, interfer-
ence brackets will be included.
If additional brackets are required they are available by
ordering the following style numbers.

Key interlocks are operative only after breakers have been
withdrawn beyond the Disconnect Position.
No modifica-
tion of the breaker
is required and storage of breaker
within the cell
is possible. The breaker can be removed
for use
as a spare without disturbing the interlock.
