Actuator
1. Power the protection release with the Vaux auxiliary power supply.
2. Power the Ekip Com Actuator contacts.
3. Load the springs.
4. Select
“close CB”
from the Ekip Touch menu
Result: The circuit-breaker closes correctly; the signals are normal.
NOTE!
The test can be performed if the protection release and the
coils are energized.
Lock for circuit-breaker in
open position (key or padlock)
1. Open the circuit-breaker
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.
Auxiliary contacts of the
circuit-breaker
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.
Circuit-breaker connected,
isolated for test, disconnected
auxiliary contacts
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.
Interlocking devices of the

1. Perform operating tests.
Result: the locks function correctly.
Device insertion and extrac-
tion
(**)
1. Perform a few racking-in and racking-out operations.
Result: in the rack-in operation the circuit-breaker is connected correctly.
