Fuse types8/3/2023 Most cartridge fuses are rated for 250 Volt to 600 Volt circuits, dependent on the class of the fuse, and rated for varying amperages as high as 600 amps, again dependent on the specific fuse. A cartridge fuse is a cylinder shaped fuse with either metal caps (ferrules) or blade contact points, at both ends. Mostly, they used in automobiles for wiring and short circuit protection. These fuses can not be rewired but they have been replaced. Blade Type HRC fuse: This type of fuses (also known as spade or plug-in fuses) comes in plastic body and two metal caps to fit in the socket. The fuse wire is enclosed in a transparent glass tube which is sealed. These fuses are used to electronic circuit. Fuse is slow as compared to circuit breakers.Heat being produced by the arc may affect the associated switches.This has to be replaced after each operation.Fuse is a safety device and the weakest part of the. It gives you a reliable performance for a long time Fuses of various types and various ratings are being used in Signal & Telecommunication department.It is capable to clear high as well as low fault current.It is very simple and easy to install.They are generally larger then screw types fuses, and have ferrule cap blade or contacts. The HRC fuse has to be replaced fully after every fault. quartz, it is used to extinguish the arc. The space within the body is surrounded by filling power i.e. It consist of ceramic body having metallic ends to which fusible silver element is connected. Characteristics of a Fuse Classification of Fuses Types of Fuses DC Fuses AC Fuses Cartridge Fuses D - Type Cartridge Fuse HRC (High Rupturing Capacity) Fuse or. These fuses are used to interrupt heavy current. The full form of HRC is high rupturing capacity fuse. The breaking capacity of fuse is limited.Unreliable Operation because for the working of the fuse it is essential to choose the element of suitable size capacity.kit-kat fuse is easy to remove & replace at negligible cost.kit-kat fuse can be used again after blowing off the fuse element.In electronics and electrical engineering a fuse is an electrical safety device that operates to provide overcurrent protection of an electric circuit. In another way we can say that, the fuse is the current interrupting devices which break or open the circuit by fusing the element and does remove the faulty device from the main supply circuit. By 1904, Underwriters Laboratories had established size and rating specifications to meet safety standards. So, to protect in the circuit from these faults fuses are used in the phase wire, so that it melts itself and protect the circuit from damage. The first fuses were simple, open-wire devices, followed in the 1890’s by Edison’s enclosure of thin wire in a lamp base to make the first plug fuse. In normal working condition of electrical network, the electric current flows through the network is within the rated limits but when a fault occurs the heating effect of current may damage the electrical circuit.
