Abstract (en)
[origin: WO2022008118A1] The invention relates to a short-circuit current limiter, comprising a vacuum switch (4) in a main current path (12) and a current limiting unit connected in parallel therewith in a commutation current path. The vacuum switch (4) comprises switching contacts (41, 42), wherein the material of the contact pieces (410, 420) of the switching contacts (41, 42) is selected such that the mean value of the chopping current is at least 8 ampere.
