Debugging operation
Opening and closing operation of circuit breaker
1. If there is undervoltage release, it must be powered first
2. First watch the indication window to determine whether the circuit breaker is in the opening state. If it
is closed, press the opening button directly
3. Shake the energy storage handle downward for 7-8 times to store energy, hear the "click" sound, and
watch whether the "energy storage" indicator window is in the "energy storage" state
4. Press the closing button to close the circuit breaker
5. Press the opening button to open the circuit breaker
6. If it is necessary to switch on again, "energy storage" is required“
Drawer seat operation
1. When the circuit breaker is in the connection position, the indicator indicates "connection", pull out the
rocker from the rocker storage and insert it into the rocker slot
2. Rotate the rocker anticlockwise to move the circuit breaker from the "connection" position to the "test"
position, and the indicator indicates "test", and the unlocking button of the three position locking
device pops up, and the rocker cannot be shaken again
3. Press the unlocking button of the three position locking device, continue to shake the rocker
anticlockwise to "separation" position, indicator indication "separation", the unlocking button of the
three position locking device pops up, and the rocker cannot be shaken again
4. Pull out the draw out handle of drawer seat and draw out the circuit breaker body
5. When installing the circuit breaker body, first pull out the draw out handle of the drawer base, place
the circuit breaker body on the draw out handle, push the circuit breaker body into the drawer base,
and push the draw out handle into the drawer base for locking
6. Press the unlocking button of the three position locking device, rotate the rocker clockwise to "test"
position, indicator indication "test, the unlocking button of the three position locking device pops up,
and the rocker cannot be shaken again
7. Press the unlocking button of the three position locking device, continue to shake the rocker clockwise
to "connect" position, indicator indicates "connect", the unlocking button of the three position locking
device pops up, and the rocker cannot be shaken again

Carry requirement
Severe collision shall be avoided as
far as possible
Do not reverse or roll the circuit
breaker
Handle with care
Heavy bus terminal of circuit breaker
Please carry it as shown in the right figure
Transportation environment temperature: - 25 ℃ ~ 55 ℃, relative humidity: no
more than 90% (at 25 ℃)
Carry way
When carrying the drawer type circuit breaker body together,
pay attention to check the drawer type circuit breaker body
The circuit breaker can be handled only when it is in the
"connected" position with the drawer base
Pay attention to check whether the circuit breaker is in "off"
state before handling the circuit breaker
The handling of fixed circuit breaker is the same as that of drawer circuit breaker
Carrying drawer seat
Insert the pull hook into the handle of the drawer seat of the circuit breaker as
shown in the figure, and then lift the drawer seat
