The FLNR070.VXID fuse is a specialized electrical component designed for a wide range of applications. It is particularly useful in the fields of industrial, commercial, and military power control and protection. The fuse operates by interrupting current in the event of a fault or overload. This article will discuss the application field and working principle of the FLNR070.VXID fuse, as well as its unique features.The FLNR070.VXID fuse is designed for a wide range of uses, including high voltage power distribution systems, such as vehicle alternators, DC-DC converters, and photovoltaic systems. The fuse is also widely used in avionic systems, with features such as low open circuit voltage, low thermal capacity, and high voltage insulation. It is also rated for use in a variety of temperatures, from ‒55°C to +125°C, making it the ideal choice for automotive, marine, and aerospace applications.The FLNR070.VXID fuse consists of a metal enclosure that houses an internal electrolytic bridge. The bridge is composed of two thin plates of aluminum and two catalytic wires. The bridge electrolyte is formulated to provide high electrical conductivity when current is passed through it. The bridge is connected to a set of contacts on either side of the enclosure, where the power source and load are connected.When current passes through the bridge, a magnetic field is generated which causes a harmonic oscillation of the bridge\'s plates. This harmonic oscillation disrupts the current flow and increases the resistance of the bridge, creating an open circuit. This action is known as "resonant arc quenching," and it is what gives the FLNR070.VXID fuse its excellent current interruption ability.The FLNR070.VXID fuse also features a unique combination of mechanical features that ensure reliability, and make the fuse ideal for scenarios where safety and dependability are paramount. The fuse is designed with a "break down window", which allows the bridge to fail, issuing an audible alarm when the window is broken. This is especially useful in avionic systems, where it’s important to be notified immediately of a fault.The FLNR070.VXID fuse also features an external arcing shield, which consists of an electrically non-conductive material surrounding the bridge and contacts. This material prevents arcing in the event of a high current overload, directing the arc away from the contacts and protecting the system.Overall, the FLNR070.VXID fuse is an excellent choice for a variety of power protection and control applications. It is designed for reliable operation in a variety of temperatures and provides excellent current interruption ability. Its unique features make it the ideal fuse for scenarios where safety and dependability are paramount.
