Electrical, Specialty Fuses: RJS 1.5SHORT Application Field and Working Principle

Fuses are electrical devices that are designed to protect electric circuits from excess current and excessive temperature. They contain a metal strip that melts when the threshold current is reached, restricting or breaking the circuit and preventing further current from flowing. RJS 1.5SHORT is a specialty fuse designed to protect high-voltage circuits. It is a component of many electrical devices, and its operation is essential for the safety and reliability of electronic devices.

Application Field

RJS 1.5SHORT is a high-voltage fuse designed for installation in components operating between 0 and 660 volts AC. It is most often used in switching power supplies, but can also be used in uninterruptible power supplies, household appliances, LED lighting equipment, motors, medical equipment, ETL-approved systems, and other high-voltage installations. It has a midget cylindrical shape and comes in two primary sizes: 1.25 and 1.5 inches.

RJS 1.5SHORT fuses are rated at 5 to 30 volts. It has a standard breaking capacity of 10A, and a maximum breaking capacity of 12A. Its standoff voltage rating is 660 volts, and its normal let-through current is 9.00A. Finally, it has a breaking capacity of 250 volts for the maximum let-through current.

Working Principle

RJS 1.5SHORT fuses are designed to protect the circuits they are installed in. When a circuit reaches its maximum current threshold, the metal strip inside the fuse is melted, thus breaking or restricting the flow of the current and preventing further damage to the circuit. This ensures that the electrical device is properly protected from any excessive current or temperatures.

The fuse\'s operation is based on the principle of Joule’s Law, also known as Ohm’s Law. This law states that the energy lost in a circuit is directly proportional to the current multiplied by the voltage. When the current in the circuit reaches its maximum threshold, the amount of energy in the circuit starts to increase, eventually melting the metal strip inside the fuse. This restriction in the current flow breaks or restricts the current and prevents further damage.

RJS 1.5SHORT fuses are also designed with safety features such as a thin wall of glass, which helps to keep the fuse securely in place. This also helps to reduce strain on the metal strip, since the glass prevents the metal strip from moving due to vibrations and shocks. Additionally, the fuse is designed to contain an air pocket, which helps to minimize electrical arcing during operation.

Conclusion

RJ 1.5SHORT is a specialty fuse designed to protect high-voltage circuits. It is a midget cylindrical shaped fuse and comes in two sizes: 1.25 and 1.5 inches. It is rated at 5 to 30 volts and is designed to protect equipment operating at 660 volts AC. Its operation is based on the principle of Joule’s Law, and it is designed to contain safety features such as a glass wall and air pocket to reduce risk of arcing and shock.
