A32 Circuit breakers can operate in the following environmental conditions:
With M Smart Unit: -40℃~ 70℃;
With H Smart Unit: -20℃~ 70℃;
A32 Circuit breakers can operate at higher temperatures than the reference temperature 40℃,in this case,the derating coefficients
shown in the table must be applied.
A32 Circuit breakers do not undergo changes in rated performance up to 2000m.Beyond this altitude ,the derating coefficients shown in
the table must be applied.
The relative humidity does not exceed 50% at 40℃,the monthly average maximum of relative humidity in the wettest month does not
exceed 90%.
The effect of surface condensation caused by temperature changes on product performance should be taken into consideration.

Undervoltage release/UVT Auxiliary contact/AX
Shunt trip release/SHT Motor operator
Closing release/XF 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.
The undervoltage release is an optional device on both manually and electrically operated circuit
breakers. It opens the breaker when its supply voltage falls to 30–60% of rated voltage. If the release
is not energized to 85% of its supply volt
age, the circuit breaker cannot be closed electrically or manually.
