Abstract (en)

[origin: EP2402973A1] The device (39) has a magnetic circuit formed by a shell (10), a fixed core and a moving core. An intercalary adjustment unit adjusts a transfer surface of an axial magnetic flux positioned between the cores and a radial surface (11) of the shell. The adjustment unit comprises calibrated elements adjoined surface against surface and formed by an alternation of magnetic sectors and non-magnetic sectors. One of the elements moves relative to other element to enable variation of the transfer surface, and is integrated in the radial surface at an opening with a serrated periphery formed by teeth. An independent claim is also included for an electric switch apparatus comprising an electromagnetic trip device.
