ABSTRACT:
A plurality of fuses are connected in a general parallel configuration for protecting a circuit, the fuses being serially connected with inductances of varying magnitude such that steady state current may be divided equally among the fuses permitting the use of fuses of lower rating. During an overcurrent surge, substantially the entire current overload is applied to each fuse in turn so that the total elapsed time for opening the circuit is less than with fuses alone.
