37415000000 fuses are designed primarily to protect electronic circuits, components and equipment in case of an overload or short circuit. They can be seen in many everyday electrical components, from light dimming modules and car audio systems to air conditioners, washing machines and industrial equipment. The working principle of these fuses is based on the simple fact that electrical current produces heat when it passes through materials with resistance. When the current passing through a device overcomes its duty limit, the fuse element melts and opens the circuits, interrupting the current and preventing further damage to the device and its components.

Fuses are generally made from special alloy with low melting point that can be seen in two general forms; the first is a cylindrical fuses with a threaded metal base. The metal base is fixed to a terminal box, providing a safe and secure connection and allowing the replacement of the fuse in case of failure. The second is a glass tube fuse with the metal base attached by a flexible wire. The metal base is inserted into a clip attached to the terminal box.

The Rated current is marked on the body of a fuse, usually on the metal base or on a label attached to it. Biased metal remains when a fuse blows and the erosion of this metal during an overload or short circuit helps to determine the cause of failure. Therefore, after opening the circuit it is important to replace the fuse with an identical one. Fuses also come with different tripping characters, specifying the amount of current the device can handle before tripping. Common values are ‘Slow Blow’, ‘Time Delay’, ‘Thermal-Magnetic’ or ‘Frequency Rated’.

37415000000 fuses are generally used in a wide range of applications where high current levels, high ambient temperatures, wide thermal dynamics or metal dust may be encountered. Such applications include Main Fuse switch gear, MV/LV switchgears, General Industrial, Pad mount fuses, MV accessories, Automotive, and Power Distribution Sub station. The Semiconductor Fuse applications include LV/MV protection, Power Electronics, Grade II Power Connectors, Solar Control Centers, Motor Protection, Control Centres, and Isolation Fuse units.

Fuses are also used in automotive applications, for instance, as protection for wiring, as well as in residential and commercial temperatures. In these applications, the purpose of the fuse is the safeguard of the wires and the other architectural elements from the direct damage of an overload or short circuit. In these and other applications the total system trip curve that is obtained by mapping the thermal and electrical characteristics of every fuse and combining them together to get the system trip curve.

37415000000 fuses come with several safety features to protect both the device and the operator, such as thermal fuses, which limit the current that can pass through them, or fuse holders, which enable the user to change the fuse without coming into direct contact with it. However, the most important thing to remember is to use the right type fuse in the right application. Fuses made for high power applications are generally heavier, bulkier, and more expensive than those made for lower power applications, so it is important to ensure you get the right part for the job.
