Abstract (en)
[origin: WO0113396A1] The invention relates to an electromagnetic switchgear (1) which comprises a current limiter (5). Said current limiter limits the electric current supplied from a current supply to a limiter current (IL) that is lower than the break-away starting current (IA). In order to be able to supply the excitation coil (2) with the required break-away starting current (IA), an energy storage element (6) is located downstream of the current limiter (5). Said energy storage element is switched to the excitation coil (2) by a switching element (7) only if enough energy has been accumulated.
