Final checks

Reassemble and check the circuit-breaker:

1.  Reassemble all the parts by performing all the operations indicated in the paragraph “Disassembly 

Operations” in reverse order and, if necessary, reconnect the auxiliary power supply.

2.  Put the movable part (breakers) in the test position (see indication TEST).
3.  Perform the following operations 10 times:

•  Opening (in both local and remote modes, if applicable)
•  Closing (in both local and remote modes, if applicable)
•  Tripping via Trip Test

4.  Perform the operations in the following sequence:

•  Open - Springs discharged
•  Open - Springs charged
•  Closed - Springs discharged
•  Closed - Springs charged

5.  Check that the following operate correctly:

•  accessories, if provided.
•  gearmotor, if provided.
•  undervoltage coil, if provided.
•  opening coil, if provided.
•  closing coil, if provided.
•  auxiliary contacts of the circuit-breaker, if provided.
•  lock for circuit-breaker in open position (key or padlock), if provided

Interlock check

Check that the vertical or horizontal interlocking devices (if provided) are installed and that they operate 
correctly.

 

WARNING! the interlocks cannot be tested in the Test or Disconnected positions.

Perform maintenance periodically as indicated in the table below.
