How does a motorised operating mechanism work?
Once it is connected to the power supply, this kind of actuator brings the blade into its open position (stand-by).
When the power is interrupted, the internal torsion spring closes the blade (safety position).
A motorised operating mechanism can be equipped with a thermo-electric fuse interrupting the power supply when the temperature in the air duct exceeds 72°C.
