8. Open-Close indicator.
9. Spring charge indicator.
10. The close bar and trip plate.
11. Steel front cover.
12. Nameplate with complete rating information.
The Type DSL-206 and DSL-416 drawout elements also
include the following components:
1. Current limiters.
2. Isolating transformers, connected in parallel with the
limiters.
3. Combination "Blown Limiter Indicator" and anti-single
phase device, connected to the isolating transform-
ers, actuated by blowing of one or more of the current
limiters. This device has individual phase indicators
and a common "RESET" button extending through
the front cover.
Each breaker is equipped with a spring-type stored
energy closing mechanism. This mechanism closes the
circuit breaker contacts with the necessary speed and
force, independently of the operator. Basically, the clos-
ing springs must first be charged or cocked before the
breaker can be closed. The springs are then released by
releasing the spring release latch. The breaker is opened
by releasing the tripping latch.
3.1 INDEPENDENT MANUAL AND POWER-
OPERATED BREAKERS

3.1.1 Closing Facilities

On manually operated breakers, the closing springs can
be charged only by hand, by means of the spring-charge
handle. The actual closing of the breaker is done only by
hand-push on the close bar. As optional equipment, the
electrical spring release attachment normally supplied
only on power-operated breakers can be supplied on
manually operated breakers.

Instructions for Low Voltage Power
Circuit Breakers Types DS and DSL
On power-operated breakers, the springs are normally
charged by an electric motor. Closing may be done elec-
trically by an electro-magnet which lifts the closing spring
release latch. Both of these operations can be done by
hand if the control power source fails.

3.1.2 Tripping Facilities

The breaker can be tripped open by hand by pushing with
the finger on the trip plate on the breaker panel or the trip
plate on the breaker compartment door (the latter is oper-
ative only when the breaker is in the connected position).
The breaker can also be tripped electrically by the follow-
ing devices:
1. Shunt trip device, optional equipment on manually
operated breakers.
2. Trip Actuator, energized from the Amptector trip unit.
3. Undervoltage Trip Device (Optional on all breakers).
4. Blown Limiter Indicator (for DSL breakers).

3.2 LEVERING DEVICE

The drawout element has four normal positions in its
compartment, determined by the levering device:
1. The REMOVE position, Figure 6.
2. The DISCONNECT position.
3. The TEST position, Figure 7.
4. The CONNECT position, Figure 8.
The REMOVE position is the first position in the compart-
ment as the element is pushed directly by hand as far as
it will go. The DISCONNECT, TEST, and the CONNECT
positions are reached only by means of the levering
device. This is hand operated with a removable crank
handle. This handle is placed on the levering device
worm shaft, which is exposed by depressing the shutter.
