Abstract: A power vacuum fuse for interrupting high voltage alternating currents. The fuse has one or more fusible, current-responsive elements spanning a pair of spaced electrodes adjacent the peripheries thereof. Leads to a high voltage line extend from the central regions of the electrodes, each of the electrodes being slotted from the central region to the periphery thereof to define a current path to each element which extends both radially outwardly and tangentially with respect to a central axis of the electrodes. The effect of the slotted electrodes is to apply a force to each element which expels it from between the electrodes upon melting of the element, such force having a tangential component which spins the arc established when all the elements are severed, thereby preventing the arc from swelling to preclude extreme volatilization of the elements and electrodes so that the circuit will be interrupted at the first natural current zero following severance of the elements.
