Undervoltage release/UVT
Shunt trip release/SHT
Closing release/XF
The undervoltage release is an optional device on both manually and electrically operated air
switch disconnectors
. It opens the switch when its supply voltage falls to 30–60% of rated voltage.
If the release is not energized to 85% of its supply voltage, the switch breaker cannot be closed
electrically or manually.

Auxiliary contact/AX
Motor operator
Miss insertion prevent device
The auxiliary contact remotely monitors ON/OFF position of power circuit breaker or
Non-automatic Switch from remote place.
Contact configuration:
44: 4NO and 4NC;66: 6NO and 6NC;
44C: 4NO or 4NC;66C: 6NO or 6NC.
The electric motor charges the closing spring of mechanism when the circuit breaker is
closed.
Factory installed only.
Mechanical charging handle can be used when maintaining or without power supply.
Equipped with a limit switch contact which signals that spring is charged.
When main breaker is inserted into the cassette, if the rating of main breaker does
not match the cassette, it will mechanically prevent main breaker to be inserted in the
cassette.
The installation method is variable according to ratings.
