Cartridge type HV HRC fuse has two fused elements- a low resistance wire and a high resistance wire. High voltage AC fuses are further subdivided into cartridge type HV HRC fuse, expulsion type HV fuse, liquid type HV HRC fuse. High voltage AC fuses have a voltage rating above 1500V and up to 138000V. Cartridge fuses are cylindrical-shaped fuses with metal ends at both sides and a fuse wire connecting the two ends. A rewireable fuse is the most common type of electric fuse used for domestic purposes as the fuse carrier can be attached or detached to the base without affecting the main switch. Rewireable fuses and cartridge type fuses are some important examples of low voltage AC fuses. Low voltage AC fuses are electric fuses having a voltage rating less than or equal to 1,500V. Owing to their simple internal structure and installation mechanism, DC fuses are most commonly used in various power systems, power devices, and household electric appliances to prevent their sudden damage due to short circuit currents.ĪC fuses are primarily of two types- low voltage fuses and high voltage fuses. On the other hand, arc produced by direct current is extremely hard to extinct which is why the electrodes in the DC fuses are placed at a considerable distance, thus increasing their size. The frequency of AC fuses can shift from 0-60 degrees which is why arc extinction can be easily done in these fuses. Also, the size of DC electric fuse is much larger as compared to the AC fuse. This characteristic of DC fuse ensures that the circuit isn’t easily turned off. Direct current fuses or DC fuses are those devices which have contact value above 0V. The main segmentation of electric fuses is done on the lines of the direct current and alternating current. The entire electric fuse market, in order to meet the varied demands of the industrial sector, is brimming with different types of fuses. This huge growth is expected to take place on account of the diverse application of fuses in the industrial sector. The electric fuse market is huge to say the least as per the report published by Research Dive, the global electric fuse market is expected to grow at a tremendous CAGR of 7.7% in the 2022-2031 timeframe. Comparative Analysis of the Different Types of Electric Fuses It thus interrupts the flow of the current and protects crucial electronic components from overloading and device failure. The simplest electric fuse is nothing but a metal strip or wire that melts as soon as a current exceeding a specific limit passes through it. A fuse is essentially a sacrificial device whose main job is to provide overcurrent protection to the circuit. The electric fuse is one of the most important components of modern-day electrical circuits.
