0034.5711.11 Application Field and Working Principle

The 0034.5711.11 is an application specific fuse derived from its parent 0034.5711 product series. Typically, the 0034.5711.11 is used for high voltage protection against short circuits and overload conditions. It is made of a molded, radial leaded, and thermoplastic body, and a ferrule for identifying the fuse by its engraved part number. The 0034.5711.11 follows the industry standard IEC 60269-2.

Application

The 0034.5711.11 is used mainly in automotive, power systems, heavy industrial and commercial environments. The fuse can be used to protect relatively low-voltage/current electronics from high-voltage/current circuit misfires, and also in heavy-duty applications, such as industrial equipment and machinery. In automotive applications, the 0034.5711.11 serves as an inexpensive and reliable alternative to circuit breakers and other large-scale protection mechanisms.

Working Principle

When an over-current occurs, the fusible element melts, thereby disconnecting the circuit and tripping the fuse. This is the most basic description of how a fuse works. The current flows through the fusible element. If the current is greater than the rated value, then the element cannot restrain the current and quickly burns out. The heat generated from burning causes the contacts of the fuse to open and interrupt the circuit. However, if the current flowing through the circuit is lower than the rated value then the fusible element will not be destroyed. This allows the current to flow within the element, allowing the fuse to remain intact.

The 0034.5711.11 has a built-in short circuit protection system, which, when initiated, will reduce the intensity of the current in the fuse. This action prevents other electrical components from being damaged due to current overload. Additionally, the fuse has a thermal protection system that shuts off the fuse completely if it gets too hot. This ensures that the surrounding components are not damaged by the high temperatures caused by the current overload.
