Fuses

The 3404.0015.11 application field and working principle is a type of fuse designed for a wider range of electronic applications. It is often used to protect components of high-end electronic equipment from voltage damage caused by strong currents, and can also be used for preventing inrush current surges.

The fuse is constructed primarily with a pair of copper butterfly-type moving contacts, which ensured reliable operation even under high-power environments, due to their strong memory effect. The contact designs also allow for either inline installation, or act as a ‘Y’-type connecting fuses in certain configurations.

The 3404.0015.11 fuses embrace two standards, IEC-M and UL-V. The IEC standard is the International Electrotechnical Commission Standardisation and require these fuses to withstand a current rating of 15A, while UL-V requires the fuses to withstand a current rating of 10A. The fuse also has a self-reset voltage of 25 volts DC.

As well as providing current flow protection, the fuse also incorporates a voltage surge protection feature, within the time-delay system, which provides persistent overload capability. This helps to protect against sudden, transient currents that could potentially damage electronic components.

The working principle of the fuse can be explained simply. When a current that exceeds the rated current limit of the fuse flows through it, the contacts within the fuse top magnetizes quickly, causing them to follow the magnetic field’s lines of force. This forces the contacts apart, breaking the circuit and preventing further current from passing through it. The contacts will remain open until they reset themselves.

In addition, the combination of contact designs also helps to reduce the arcing effect, which could damage the electronics connected to the fuse. The IEC standard for low-risk fuses also conforms to the fundamental measure of IEC 61010-1.

Overall, the 3404.0015.11 fuse offers an excellent option for many electronic applications, providing both an effective level of current protection, along with the added safety feature of surge protection. The design ensures its compatibility with modern components and makes it highly reliable under high voltage conditions.
