25CJ Series current limiting fuses are typically used in low voltage & applications. They are designed to provide reliable short-circuit protection for medium to hi-resistance circuits. They work by breaking the electrical circuit when the current is higher than a certain threshold. This is done by vaporizing the metal fuse element placed inside the fuse.
This type of fuse is made of a thin conductive metal which melts in case of an overload or short-circuit condition. When the voltage across the fuse increases, the thin metal bonds break and the metal element melts. This breaks the circuit and prevents further damage to the equipment.
The 25CJ itself is a cylindrical device with an upper and lower end. The internal body of the fuse is composed of a blend of zinc and aluminum granules which are mixed in a heat and pressure bonding process. The bonded core is molded into a cylindrical plastic body and the split contacts are attached to the body of the fuse.
The working principle of 25CJ fuses is based on the thermal time-constant which determines the operating characteristics. The current through the fuse is measured by the fuses internal copper conductor. This copper conductor has a very low impedance and the current can be estimated accurately. To capture and break the increasing current, the fuse has a time-delay feature which depends on the gauge of the fuse. The heat produced by the current is absorbed and stored in the granules, eventually causing them to melt and break the fuse board.
25CJ fuses have many applications in electrical engineering, from controlling the current flow in power systems, to preventing short-circuits in computers. These fuses offer high performance protection from overload and short-circuit conditions, and provide reliable current limiting for medium-voltage applications.
These fuses are available in various sizes and current ratings. 25CJ fuses are typically rated at up to 4000 volts and up to 200amps. The maximum current rating of the fuse depends on the total length, the number of contacts connected, and the material used for the fuse element.
25CJ Series current limiting fuses are reliable, efficient, and easy to install. They provide reliable protection for numerous applications and can be used in conjunction with other electrical components. These fuses save time and money in installation and offer excellent protection from overloads and short-circuits.
