Fuse Auto Changeover System is intended to monitor the intactness of fuses that are used in the signalling circuits in cabins. Whenever any fuse blows, the circuit automatically changes over to a spare fuse provided in the system. The change-over to spare fuse in instantaneous & there is no break in the signalling system. Hence, it prevents failure caused due to a blown fuse. It also gives an audio-visual alarm for the blown fuse
