Electrical fuses are devices designed to protect electrical systems and components from overheating and potential damage resulting from short-circuiting or other electrical disturbances. Fuses can be categorized as either specialty or general-purpose, and are available in many different shapes and sizes. The 004255504 from Littelfuse is a specialty fuse designed to provide fast and reliable protection for vital electronics and other sensitive components.

The 004255504 fits into standard .25 inch round fuse holders. Its low breaking capacity and quick blow characteristics provide circuit protection with limited added impedance while still allowing high inrush currents, making it ideal for protecting components from short-circuits or overloads. It has high temperature endurance and is pressure-sensitive, meaning it uses temperature information to detect and trip when necessary.

The 004255504 is designed to have more consistent performance than other fuse prototypes, ensuring safe and reliable protection when used in critical application areas. It has a maximum current rating of 10A, with a 4V nominal rated voltage. The 004255504 can be used in circuits powered by both AC and DC power, across a wide range of frequencies. Its body is constructed of tin-plated brass, and its contacts are made out of silver-plated copper. It has a -25°C to +65°C operating temperature range when mounted directly to a panel, and a -55°C to +80°C operating temperature range when used with a holder.

The 004255504’s working principle is simple and effective. It is designed to interrupt the flow of current when an overload or short-circuit occurs, thereby preventing electrical system damage and potential fire hazards. It works by using a current limiting element, which is triggered when current passes through it, causing resistance and heat to build up. As current increases, the heat increases and when it reaches the fuse’s breaking point, current flow is interrupted, breaking the circuit and protecting the components from potential damage.
