Abstract: PROBLEM TO BE SOLVED: To protect a device without problems in the event of natural melt- down or accidents of a fuse by connecting in parallel a plurality of fuses provided with four partite magnetic bodies around them, connecting the fuses in series with the device, and balancing currents through the fuses. SOLUTION: Fuses 21 to 23 held by a support 4, with a silicon steel plate magnetic body 3 divided into four and placed around them, are connected in parallel, and electrodes 5 at both ends of each fuse are connected to a connecting conductor 1 by means of connecting bolts 6.

The size of the gap and the thickness of the silicon steel plate are set so that for the frequency components of currents flowing through the fuses, the influence of inductance caused by the magnetic bodies 3 becomes greater than the resistance value of the fuse. Therefore the shielding effect of the magnetic bodies 3 reduces the influence of mutual inductance from the other fuses, balancing the currents through the fuses.  Thus the device can be protected without problems in the event of natural melt-down or accidents.
