Entellisys Low Voltage Switchgear
Chapter 5. Installing and Removing Circuit Breakers
CAUTION: When using the switchgear hoist, do not un-
wind the cable completely from the drum. To lift the
breaker, turn the hoist operating crank clockwise. To
lower the breaker, turn the hoist operating crank counter-
clockwise.
ATTENTION: Il ne faut pas dérouler complètement le
câble du cylindre lorsque l’on utilisse le treuil du dispositif
de commutation. Tourner la manivelle opérant le treuil
dans le sens des aiguilles d’une montre pour soulever le
disjoncteur. Tourner la manivelle opérant le treuil dans le
sens contraire des aiguilles d’une montre pour abaisser le
disjoncteur.
4. Fully withdraw rails to stops.
5.
Slowly lower and guide the breaker to allow the 4
breaker wheels to align with the rails. See Fig. 5-7.
Remove the lifting device. The breaker is now
positioned on the drawout rails.
6.
Roll the breaker into the compartment until the racking
forks meet the racking pin, this is the DISCONNECT
position. If an incorrect breaker has been installed, the
interference pins on the breaker will interfere with the
rejection pins in the compartment prior to reaching the
DISCONNECT position. See Fig. 5-8. At this point, the
racking forks are contacting the fixed racking pins in
the compartment.
7.
Slide rails back into compartment. Close the com-
partment door and rotate latch ¼ turn counter-
clockwise.
8.
Engage the racking handle by pushing and holding the
trip button in the breaker escutcheon, sliding the cover
just below it to the right, releasing the trip button, and
inserting the handle on the jackshaft. See Fig. 5-9.
9.
Rotate the handle clockwise as far as it will go. As you
rotate the handle clockwise, the breaker will travel from
the DISCONNECT, through the TEST position (you will
notice an audible click), and then into the CONNECT
position. The breaker position can be seen on the
indicator, located on the breaker escutcheon.
Fig. 5-8. Push the breaker in completely. Close the door.
