Fuseholders are an indispensable part of wire and cable assemblies, making sure to protect circuitry by limiting current in an circuit. A 03455LF1X fuseholder, designed for 035 size axial lead fuses, is no exception. Perfect for battery packs as well as automotive applications, this fuseholder provides excellent protection in a low profile package, allowing for seamless fitting into even the most confined of spaces.

Various Configurations

The 03455LF1X is available in a variety of configurations. It features a two-piece design with keytop reinforcement to ensure strength and minimize electrical contact stress. The screw down terminals provide a secure connection to fused wire in front and back. The fuseholder is also available with or without the top finger grip and seal cap assembly, allowing it to be attached to a variety of positions. Overall, this fuseholder is perfect for surface mount and through-hole applications which require a space-saving package.

Power Rating

The 03455LF1X is rated for a maximum of 10A @ 125VDC, making it perfect for a wide range of domestic and international applications. The fuseholder is also rated for operation in temperatures as low as -25°C (-13°F) and as high as +85°C (185°F). This makes the 03455LF1X suitable for a variety of environments, including those with high levels of humidity, dust, and other contaminants.

Working Principle

A fuseholder works based on the simple principle of limiting the flow of current in an circuit, thereby preventing damage should an excessive current flow. In order to protect the circuit, it is important that the fuseholder is properly mounted and the fuse installed into the holder is of the proper size. When a too-high wattage fuse is installed in the fuseholder, the holder is unable to reduce the flow of current quickly enough, resulting in damage to the circuit.

When the fuseholder is correctly sized and a correctly-sized fuse is installed, current is allowed to flow as normal through the circuit. However, should an electrical malfunction arise and the current be too high for the fuse to handle, then the fuse will blow to prevent the current from damaging the circuit. This can then be replaced with a new, correctly-sized fuse, allowing the circuit to continue functioning.

Applications

The 03455LF1X is perfect for a variety of applications, including automotive, battery packs, and surface mount devices. Its two-piece design and low profile make it suitable for even the most confined of spaces. The fuseholder is perfect for applications where it is necessary to protect the circuitry by limiting its current flow, including those with high levels of humidity and dust.

The 03455LF1X is a reliable, cost-effective solution for a variety of fuseholder needs. By properly mounting the holder with a correctly-sized fuse, the holder is able to limit the flow of current, protecting the circuit from potential damage.
