A miniaturized and sleek protective device M. Priyanka, Mahindra&Mahindra, India D. Boobala Krishnan*, Mahindra&Mahindra, India T.Vijayan, Mahindra& Mahindra, India Keywords-Fuse, Lightweight. Research and/or Engineering Questions/Objective: Now-a-days there is lot of advancement coming in automobiles. Earlier the electronics were used in engine and engine compartment areas. Now all hydraulics and transmission have been operated by electronics. The role of electronics like sensors, actuators increasing day by day for lifting and moving operations. With increase in electronics circuit, there is complex in wiring harness and packaging space for fuse box is premium Limitations: Limitations of placing other devices. Occupy more space and weight in the vehicle. Packing constraint due to vibration and thermal management issues. Methodology: Two different fuse of same rating can be given in one fuse and we can reduce the wire size. By this method we can save many fuses and reduce the fuse box size. An optimized fuse box minimizes the length of circuit. It translates the system into less plastics. This type of system is highly useful in systems such as ECU and IP Panel, where similar rating of loads placed next to each other. Results: If multiple circuits are on one fuse, the fuse rating will be higher to handle all of the loads. The higher fuse rating drives larger wire sizes. By individually protecting each circuit, the fuse rating can be based on the single load. The lower fuse rating allows smaller wire size to be used.Typical Example of this circuit is low beam application of headlight. The current drawn by these lamp are so high and so does the dissipation of power.By giving one input and two output, we are increasing the surface area thereby reducing thermal management issues What does the paper offer that is new in the field including in comparison to other work by the authors?. It makes use of miniaturized and sleek protective device which can be effectively used for high current application in optimized space. Thermal dissipation of overcurrent issues can be handled effectively. Conclusions. The highly advantage in this system, the short of one circuit doesn't impact the other circuits. It will hold good for other system. This system saves cost, space and weight primarily. In some cases where fuses are limited, customers often fuse multiple wires with one fuse. This means the fuse has to be able to withstand the loads of all of the circuits at the same time.
