a fuse is a metal link calibrated to melt when a larger current than which it was designed to carry is exceeded that way it protects the wiring from catching fire and setting the house on fire always use the right fuse in a circuit
A device that melts under high current , not high voltage is a circuit protective fuse. There are many fuses that are rated for voltages in the 10,000 volt range. It is the over current that trips them.

There are two main devices. One is the circuit breaker. It provides a dual function where in it can detect short circuits with its internal magnetic sensor and overloads with its internal bi metallic strip. The other device is a fuse. It operates by melting a fusible link, that breaks the fault current that is in the circuit, when a high current rush through the fuse.
Circut Breaker
A fuse is used in a circuit to protect the other elements in a circuit. Fuses are rated at different currents and voltages. When the rated current is exceeded the fuse will blow. For that reason fuses are placed in circuits to protect other more expensive items. For example you find fuses in your home. If there was a sudden surge in current coming into your house the fuse will blow and power will be cut to the circuit it is attached to. If that fuse wasn't there the other elements in that circuit would be exposed to the current surge. This would cause damage to that object and if it is something like a computer or tv etc they are not that cheap to replace. So ultimately a fuse is put in place to make sure that other equipment isn't damaged by current surges etcbecauswe the yd o#
To protect the components in the circuit from overcurrents.
Circuit breaker or fuse.fuse
Instead of blowing a fuse you'll blow up a light bulb if there is a surge.
It is used to protect circuits ranging from 3.5-30amps, so almost everything.
The F6AL250V fuse is a 6 amp fuse rated for a maximum voltage of 250 volts. The "F" indicates that it is a fast-acting fuse, designed to blow quickly to protect circuits from overloads. The "A" signifies that it is an automotive or similar type fuse. Always ensure that the fuse rating matches the specifications of the circuit it is intended to protect.
If you have a short in an appliance or wiring, the fuse will blow to keep a fire from starting in your wiring.
Fuse
A GDC fuse, or General Dual Circuit fuse, is designed to protect electrical circuits from overloads and short circuits. It features two separate circuits within one fuse, allowing it to provide protection for multiple circuits simultaneously. GDC fuses are commonly used in various applications, including industrial and commercial settings, to enhance safety and reliability in electrical systems. Their design helps ensure that equipment remains operational while safeguarding against potential damage from electrical faults.
A fuse works by breaking the circuit when there is too much current flowing through it, which helps prevent damage to the electrical components from overheating or overloading.
A fuse with two black wires attached is typically called a "black wire fuse." The black wires serve as the connections for the electrical circuit, with the fuse serving to protect the circuit from overloading or short circuits.
Each device has its own special use. Glass fuses can protect circuit at very low amperages. They are usually used to protect printed circuit boards and control panel circuits. Breakers protect circuits from short circuits and overloads. These devices are used in service distribution panels to protect the wires that feed the loads. Circuit breakers can be from 15 amps up into the thousands of amps.
It is not recommended. The design of the equipment called for the 315ma fuse. To up size it to a larger fuse is taking the equipment out of its manufactured specification. Fuses are used to protect circuits. If you install an oversized fuse you override the designed in protection.
