Abstract (en)
[origin: EP2743947A1] The shaft (8) has a mechanical connection unit (45) located in vicinity of an end of the shaft. Two zones are provided on two sides to retain mobile contacts (7) and a contact pressure spring. A set of parts is formed in certain shape to ensure rigidity of the shaft and transmission of a mechanical torque throughout the shaft. A reset unit is formed in corresponding shape of the shaft to allow resetting of various thermal triggers belonging to different phase subsets after an opening on defect. An independent claim is also included for an electric current breaking apparatus.
