Chapter 3. Breaker Operation
7
NOTE: Les contacts principaux du disjoncteur
ne peuvent être fermés si l’une ou l’autre des
conditions suivantes s’appliquent:
• Le mécanisme de retrait du ressort est en
tout autre position que: TEST ou CONN , tel
que montré à la position indicatrice du dis-
joncteur.
• L’alarme optionnelle avec cloche n’a pas
été remise en place après un blocage par
surintensité de courant.
• Le mécanisme optionnel de déclenche-
ment par sous voltage n’a pas été
enclenché.
• Le verrouillage réciproque optionnel de
réseaun'était pas réenclenché après une
opération d'enclenchement.
Il faut que ces situations soient corrigées avant
de procéder à la fermeture du disjoncteur.
Toute tentative de fermer le disjoncteur avant
que ces conditions ne soient corrigées pourra
résulter en une décharge des ressorts de fer-
meture sans fermer les contacts principaux.
Opening the Breaker
Open the breaker contacts with any of the following
methods:
• Depress the OPEN button on the front of the breaker.
• Open or trip the breaker using the Entellisys™ HMI.
• Energize the (optional) Shunt Trip accessory by
applying the rated voltage to secondary disconnect
terminals 5 and 7.
Padlock Operation
The padlock provision prevents the breaker from closing
by holding the trip latch in the tripped position. Up to
three padlocks with 1 / 4 " to 3 / 8 " diameter shanks, or scis-
sor-type safety lockout hasps may be inserted at one time.
To install a padlock, use the following procedure:
WARNING: Be sure to test for proper
operation of the mechanism, as described in
step 1, before using it to secure the breaker.
AVERTISSEMENT: Assurez-vous de tester que
le mécanisme opère correctement, tel que
décrit à l'étape 1, avant de l'utiliser pour fixer le
disjoncteur.
1. To check for proper installation of the padlock
mechanism, hold in the OPEN button, pull out the
padlock slide, insert a 1 / 8 " rod or #10 gage solid
wire, and attempt to close the breaker.
The breaker must not close.
2. While holding the OPEN button in, slide the pad-
lock plate out and hold it in place.
3. Put the padlock or safety lockout hasp into one of
the three holes in the padlock plate; this will
prevent the plate from returning to its unlocked
position and prevent the breaker from closing.
3.2 Control Wiring
Figure 3 is the wiring diagram for the breaker control cir-
cuitry. Table 3 lists the secondary disconnect terminals
and the items connected to each. The location of the
secondary disconnect is illustrated in Figure 4.
3.3 Breaker Interlocks
EntelliGuard breakers are equipped with a number of
safety interlocks to prevent improper operation of the
breaker.
Draw-Out Interlock
The Draw-Out Interlock prevents the breaker from being
closed when the breaker is between the CONN nor TEST
positions. A pin on the side of the breaker engages a
ramped cam in the switchgear cubicle. When the pin is
lifted 3 / 8 " the breaker is held trip-free.
An additional interlock holds the breaker trip-free when-
ever the racking handle is engaged with the draw-out
mechanism racking screw.
Contact Interlock
The Contact Interlock prevents the racking handle from
engaging the draw-out mechanism racking screw when-
ever the breaker contacts are CLOSED . The Racking
Handle (catalog number 0324B4721G001) has a recess
that prevents the tool from engaging the square drive on
the racking screw when the interlock is active. This
prevents changes to the breaker’s position with the main
contacts CLOSED .
CAUTION: Use of a tool other than the GE
Racking Handle 0324B4721G001 may render
the Contact Interlock ineffective.
CAUTION: L’utilisation d’un outil autre que
le GE Racking Handle 0324B4721G001 peut
rendre le mécanisme de verrouillage des
contacts inefficace.
