Product Description

1. When operating at 25ºC, the rated current of a fuse is usually reduced by 25% to prevent harmful melting. Most traditional fuses use materials with a low melting point, making them sensitive to changes in ambient temperature. For example, a 10A rated fuse is not recommended to operate at currents greater than 7.5A in a 25ºC environment.
2. The voltage rating of a fuse must be equal to or greater than the effective circuit voltage. The general standard voltage rating series is 32V, 125V, 250V, and 600V.
3. The resistance of a resistive fuse is not important in the entire circuit. Since the resistance of a fuse with an ampere rating less than 1 is only a few ohms, this issue should be considered when using fuses in low-voltage circuits. Most fuses are made of materials with a positive temperature coefficient, so there is a difference between cold and hot resistance.
4. The current-carrying capacity of a fuse is tested under 25ºC ambient temperature conditions, which is affected by changes in ambient temperature. The higher the ambient temperature, the higher the working temperature of the fuse, and the shorter its lifespan. Conversely, operating at lower temperatures can extend the life of the fuse.
5. The rated breaking capacity, also known as interrupting capacity, is the maximum permissible current that a fuse can actually melt under rated voltage. During a short circuit, the fuse will experience instantaneous overload currents greater than normal operating currents multiple times. Safe operation requires the fuse to remain intact (without bursting or breaking) and eliminate the short circuit.
