Aircraft Fuses Must Protect

The ever-increasing list of electric equipment needed for the satisfactory performance of the modern airplane has brought the electric system from a place of relative unimportance to one which cannot be ignored. The electric equipment must not fail, particularly on combat planes. Therefore, the protective devices must be designed and applied to permit the equipment to function as long as it can supply any useful work but to remove it from the circuit when it has ceased to function or has become a hazard. This type of electrical protection is obtainable with fuses of special design when applied properly.
