6.1.5  Inspection of contacts’ tilt and gap 

         Pay attention to the warnings, Section 1! 

 

A) Remove the arc chute and adapter 

• 

See 6.1.4-A/B.

 

 

B) Check the tilt of the main contacts

 

• 

[Fig.  45]. Use the hand lever for slowly closing the 

main contacts. 

• 

[Fig. 46]. Once the pre-arcing contact touches arc 
runner, check the air gap between main contacts. The 

gap between main contacts shall have more 1mm 

[0,04in]. 

• 

In case of insufficient tilt, replace the pre-arcing con-

tact with new one. See 6.2.1 and 6.2.2 for details. 

• 

If required tilt is not available, even after component 

replacing, please contact GE Service Team. 

 

C) Check the air gap of pre-arcing contact

 

• 

Close the breaker and 

secure the solenoid drive 

against unintended opening. 

See 1.2.1. 

• 

[Fig. 47]. Check the air gap between the pre-arcing 
contact and main arm. It shall be minimum 1mm 

[0,04in]. 

• 

In case of insufficient tilt, replace the pre-arcing con-
tact with new one. See 6.2.1 and 6.2.2 for details. 

• 

If required gap is not available, even after contact re-

placing, please contact GE Service Team. 

 

D) Install back adapter and arc chute 

• 

See 6.1.4-G/H.

 

 

6.1.6  Inspection of the screw connections 
     

      Pay attention to the warnings, Section 1! 

 

• 

[Fig. 41]. Tighten front- and backside of the arc runner 
screw connections (3) and (5). Use torque of 10Nm 

[88lbf*in]. 

• 

[Fig. 41]. Tighten arc chute connections (4). Use torque 

of 5Nm [44lbf*in]. 

• 

[Fig. 41]. The arc runner’s screw connections (3) must 
be secured by means of lock washer. 

• 

[Fig. 41]. The arc chute’s screw connections (4) must 

be secured by means of flat washer. 

• 

Any other screws shall be tightening with applied 

torques from Table 3-D. 

• 

 Ensure that the screws are in good condition, that 

thread  and nest are not damaged. Surface shall be 

free from rust. Replaced any screw, which does not 
fulfil above conditions.  

• 

This check must be carried out prior to commissioning 

and after every maintenance. 

 

6.1.7  Inspection of the mechanic components 

 

Only GE Service Team or its representative shall do these 
inspections. These are related with major disassembling 

and adjusting of the breaker. Customer without supervi-
sion of trained specialist shall not execute these.
