Electric specialty fuses, such as the 170M8637, come in a variety of shapes, sizes and characteristics to match their intended application. An understanding of the fuse design and operating principles provides the knowledge required to identify and troubleshoot component failures. Knowing the functional characteristics of a fuse helps to select and apply it correctly in a circuit.

Functional Principle of Fuses

The basic function of an electric specialty fuse is to protect electrical circuits from overload and short-circuit conditions. This is done by ‘blowing’ or ‘tripping’, which is a process of opening the circuit when a pre-determined current is exceeded for a given time. A switch or mechanical device hides the un-energized fuse element. As soon as the circuit current reaches the nominal value of the fuse, the thermal or mechanical breaking of the element interrupts the circuit, thus disconnecting the load and protecting the electrical components of the circuit.

Types of Fuses

Fuses are available in a variety of shapes, sizes and ratings for different types of circuit applications. Generally, they can be categorized based on their characteristics or technology used. Slow Blow Fuses are used to protect components that are vulnerable to short-term overloads and transients, while Fast Acting Fuses are used for providing over current protection in circuits with medium to high overload currents. Fuses can also be classified by their body style or housing such as round, rectangular, cylindrical, and square or PCB mounted types. It is essential to choose the correct type of fuse for an application, thereby ensuring the safety and reliability of the system.

Designation of Fuses

The designation of a fuse usually includes several parameters such as the rated current, blow-speed and operating voltage. The rated current is the maximum current which the fuse is designed to carry before a specified time, if exceeded it will blow or trip. The blow- speed is a measure of the reaction time taken by the fuse to open a circuit when the nominal current is exceeded. The Voltage Rating or Operating Voltage is a measure of the maximum voltage a fuse is designed to withstand without suffering from deterioration or excessive arc.
