Fuses: 045103.5NR Application Field and Working Principle
Fuses are designed to protect electrical circuits and devices from excessive current, preventing damages and injuries. The 045103.5NR fuse is a type of UL and CSA listed multi-dwelling unit rated time delay fuse. This fuse has a voltage rating of 250V AC, current rating of 100A, and interrupt rating of 10000A at 250V AC. This type of fuse is suitable for single and two family dwellings under specific conditions, such as with circuit breakers and switches in fused systems for overcurrent protection.
Since the application of this fuse is specific to multi-dwelling unit, it is designed to be used in several different electrical systems. DryNer’s 045103.5NR fuses are typically found in branch circuits and feeders supplying appliances or equipment in single or multi-family dwellings, as well as those circuits supplying both single and multi-family dwellings. In dwelling units, such as apartments, hotels and motels, these fuses are used in branch circuits or feeders supplying local loads or lighting elements. In other buildings, such as schools, hospitals, universities and churches, these units are also applicable for local loads and lighting elements.
The 045103.5NR fuse is a time delay fuse designed to opens automatically after a specified amount of time, allowing it to be rated for use on larger, higher current circuits than other types of fuses. This time delay feature also ensures that the device is not easily tripped by surges or harmless temporary inrush currents, allowing equipment and components to function properly. The fuse is designed to open or “blow” before reaching its maximum current rating, thus protecting devices and circuits from potential damage.
The working principle of this type of fuse lies in its construction. The 045103.5NR fuse has two metal strips connected within a ceramic tube. When an overload current flows through the fuse, it heats the metal strip and it expands. This interrupts the circuit and releases the fuse from its socket, allowing interruption of the circuit shape and preventing potential damage to the circuit.
The 045103.5NR fuse from DryNer is designed to provide reliable overcurrent protection, protection from hazardous overloads, and circuit interruption in the event of an overload. This unit is robust and reliable, providing optimal safety for devices and circuits. This fuse is ideal for multi-dwelling units, as it is UL and CSA listed, making sure that it meets the standards for safety and reliability.
