Abstract (en)

[origin: EP0523420A2] The invention relates to a short-circuit instantaneous trip mechanism having a tripping element (10) which is acted on electrodynamically and releases the latching. The tripping is blocked by a locking device, to be precise with a time delay which is in the millisecond range. The locking device is preferably constructed as an independent structural unit and, in addition to the baseplate (30), has a clamping lever (32) and a spring (34) which is connected to a flywheel body (36) which is supported such that it can rotate. The clamping lever (32) and the flywheel body (36) are constructed in a self-resetting manner with respect to the disconnection process, by means of a resetting spring (35). <IMAGE>
