Safety Features
Type DS (DSL) Breakers are manufactured with several
built-in interlocks and safety features to reduce hazards
and provide proper operating sequences. UNDER NO
CIRCUMSTANCES SHOULD THEY BE MADE INOP-
ERATIVE AS THIS MAY RESULT IN BODILY INJURY
OR PROPERTY DAMAGE.
1. Positive mechanical indicators on front panel show
whether the breaker is open or closed, and whether
the closing spring is charged or discharged.
2. Closing Spring Automatic Discharge - Mechani
cal
interlocking automatically discharges the closing
springs when the breaker is removed from its com-
partment.
3. Mechanical interlocking prevents levering of breaker
unless its contacts are open. Contacts cannot be
closed until the breaker is levered into TEST or CON-
NECT positions.
4. Mechanical interlocking prevents closing of breaker
contacts while it is being levered into or out of its cell,
or while it is standing in any intermediate location
bet
ween the TEST and the CONNECT positions or
the DISCONNECT position.
5. Provisions for Padlocking-Breakers can be padlocked
open to prevent electrical or manual closing. This
padlocking can also secure the breaker in the con-
nected, test, or disconnected position by preventing
levering.
6. In the CONNECT position automatic mechanical
interlocking prevents the disconnecting or withdrawal
of a closed breaker. This avoids drawing dangerous,
destructive arcs on the d
isconnecting contacts when
the circuit is energized.
7. In the REMOVE position mechanical interlock system
prevents the closing springs from being charged or
remaining charged.
8. The integral fuses on Types DSL-206 and DSL-416
breakers are inaccessible until the breaker is com-
pletely withdrawn from its compartment, thereby
assuring complete isolation.
Likewise, the Type DSL-632 and DSL-840 fuses are inac-
cessible until the separate fuse truck is
completely with-
drawn and the fuses isolated. The fuse truck is key
interlocked with the breaker to prevent withdrawing or
insertion unless the breaker is open.
