Fuses Nimrod

An electrical fuse is a one-time device that breaks a circuit in the event of an overcurrent or short circuit. A fusible electrical fuse is usually made of a thin filament that burns out when a certain amount of current is exceeded, thus breaking the electrical circuit. The fuse filament is usually embedded in a glass body or, in the case of a knife fuse, in a plastic casting of a different color. This color gives us the maximum current that the fuse is capable of handling.

Application of fuses

A fuse is an electrical device that protects electrical lines, electrical equipment, electronic components or circuitry from damage by excessive electric current. By switching off and breaking the circuit with a fuse, the electrical equipment of an airsoft gun is protected, such as not only mosfets, active brakes, processor units, but also motors and batteries too.

The principle of the fuse function

The principle of the fuse is that the fuse forms the weakest point of the electrical circuit. When an electric current passes through the fuse, a voltage drop and a power loss in the form of heat is generated at the electrical resistance of the fuse conductor. This causes the fuse cartridge conductor to heat up. Depending on the magnitude of the current, the power loss on the fuse conductor increases. The power dissipation is a function of the square of the current and therefore the time to fuse conductor melting is significantly reduced with increasing current magnitude. By melting the fuse conductor and extinguishing the resulting arc, the electrical circuit is interrupted.
