Abstract
An overcurrent protection arrangement comprises a switching circuit that is intended to be series connected in a line of the circuit to be protected and which will allow normal circuit currents to pass but will open when subjected to an overcurrent. The arrangement includes a pulse generator which will generate pulses when the switching circuit has opened that reset, or attempt to reset, the switching circuit to its conducting state. Only a predetermined finite number of pulses or pulses for a predetermined finite time are generated, so that the circuit will quickly function again after having been subjected to a current transient but will not continually attempt to reset in the case of equipment faults.
