doesn't close when
the closing push-
button is pressed
The trip signal of the protection
release has not been reset
Press the push-button of the
mechanical reset or operate the
electrical reset remotely.
The open position key lock is
activated
Unlock the lock in open position
using the relevant key
The circuit-breaker is in an
intermediate position between
connected and test
Complete the connection
operation
The under-voltage coil is not
energized
Check the power supply circuit
and the power supply voltage
The opening coil is permanently
energized
Correct condition of operation.
The release pushbutton is
pressed (withdrawable version)
Rotate the crank to complete
or the plug-in or unplugging
operation initiated
The circuit-breaker
doesn't close when
the closing coil is

Measure the voltage: it should
not be lower than 85% of the
rated voltage of the coil
The power supply voltage is
different to that indicated on the
rating plate
Check the voltage on the rating
plate
The cables of the coil are
not inserted correctly in the
terminals
Make sure there is continuity
between cable and terminal
and if necessary reconnect
