2. Keep the opening push-button pressed
3. Turn the key and remove it
4. Attempt the circuit-breaker closing operation.
Result: Both manual and electrical closing are prevented.
1. Connect the auxiliary contacts to appropriate signalling circuits or to
the multimeter.
2. perform some closing and opening operations on the circuit-breaker.
Result: signalling occurs normally.
1. Connect the auxiliary contacts to appropriate signalling circuits.
2. next bring the circuit-breaker to the connected, isolated for test and
disconnected position.
Result: the signals due to the relative operations are normal.
1. Perform operating tests.
Result: the locks function correctly.
1. Perform operating tests.
Result: the locks function correctly.
1. Perform a few racking-in and racking-out operations.
Result: in the rack-in operation the circuit-breaker is connected correctly.
There is no particular resistance during the first turns of the handle.
Verify the installation The value of the power supply auxiliary voltage of the
auxiliary accessories must be between 85% and 110% of the rated volt-
age for the auxiliary accessories.
1. Power the protection release
Result: Verify that Power LED is lit up on each accessory present.
Make sure that the Local Bus communication line is activated on the
protection release.
1. In the case of Neutral external sensors, single-pole or differential, to set
the model and protection parameters appropriately.
Result: No alarm present on the protection release.
WARNING! During this phase the circuit-breaker must be
open and withdrawn (if withdrawable).
