Abstract (en)
A current limiter (10) comprises an electromagnetic drive unit (30) adapted to limit the current carried by a current circuit by displacing at least one movable contact piece (13, 15) from a responsive stationary contact piece (12, 16) in response to at least one current phase carrying an excessive current. The current limiter (10) further comprises a bimetallic block (18, 19) adapted to undergo such a thermal expansion in response to at least one current phase carrying an excessive current that the bimetallic block (18, 19) after the expansion is adapted to prevent said at least one movable contact piece (13, 15) from returning to contact with the responsive stationary contact piece (12, 16).
