Abstract
High-current, current-limiting circit interrupter having arcing contacts connected in parallel with the main contacts. Impetus means open the main contacts strikingly to switch the short-circuit current to the high-resistance arcing circuit. Electrodynamic means cause the arcing contacts to remain closed a short lapse of time after the transfer of the short-circuit current to the arcing circuit. Further electrodynamic means cause the arcing contacts to open sequentially.
