These electrical fuses are commonly used in low-voltage electrical circuits and come in different shapes, constructs, and sizes. This type of electrical fuse works in a circuit with a voltage rating that is lower than or equal to 1,500V. We then split these into two sub-categories low-voltage electrical fuses and high-voltage electrical fuses. Now, AC fuses and DC fuses are the two main categories of electrical fuses. The electrical fuse isn’t needed to be larger, as the alternating current stops supplying itself. This means that when the strip melts, the arc is easily extinguished when this voltage drops to zero. They don’t need to be made larger thanks to the alternating frequency of the current supply.Īlternating current is supplied at a voltage that goes from a maximum level to a minimum (0V) level usually 50 to 60 times in a minute. AC FuseĪC fuses, on the other hand, are electrical fuses that work with alternating current circuits. To prevent arcing, the DC fuse is made larger, which increases the distance between the two melted ends of the strip. This defeats the purpose of the fuse as power still flows through the circuit. However, due to the constant current and voltage supply in the circuit from the DC source, a small gap between both ends of the melted strip creates a possibility for constant arcing. When there is excess current or a short circuit in a DC fuse and the metal strip melts, a gap is produced within the circuit. ![]() Although this is the main factor that differentiates them from Alternating Current (AC) fuses, there’s one more characteristic worth mentioning.ĭC fuses are typically designed to be larger than AC fuses to avoid an extended electrical arc. Simply put, DC fuses are the type of electrical fuses used with direct current circuits. These include:Īll these will be individually explained in detail for your full understanding. There are over 15 types of electrical fuses differentiated by working principles, construct, and applications. How The Fuse Current Rating Size Is Calculated.
