42515000101 - Application Field and Working Principle of Fuses

Fuses are an electrical device that is designed to protect circuits, equipment, and people from electrical overload and shorts. Fuses are commonly used to protect circuits, prevent accidental fires, and protect people from electric shock. They are also used to control the flow of electrical current and ensure that circuits work correctly.

Objective of Fuses

The primary objective of a fuse is to provide protection from electrical overload. Fuses are rated according to their current-carrying capacity. If the current drawn by a circuit exceeds the fuse\'s rated capacity, the fuse will "blow" or open, interrupting the flow of current and protecting the circuit from overload.Fuses are also used to minimise the potential damage to electrical equipment due to shorts. A short occurs when there is an unintentional path for the electrical current to flow, usually caused by a faulty connection or wiring. When a short circuit occurs, too much current is forced through a circuit and can cause significant damage to the components and circuitry. A fuse will detect the short and open the circuit, thus preventing further damage.

Types of Fuses

There are several types of fuses including blade, ceramic, glass, plug, and reed. Blade fuses are the most common type and are available in a variety of amperage ratings. They consist of a metal strip that is connected to two metal strips that are connected to the circuit. The metal strip is designed to open or "blow" when the current flow exceeds its rating.Ceramic fuses are also common and typically rated for higher amperages than blade fuses. They consist of a porcelain tube that contains a powdered metal element that melts when the current exceeds the fuse’s rating.Glass fuses consist of two metal strips that are connected to a tiny glass tube filled with a low melting point alloy. When the current increases beyond the rated capacity, the alloy melts, breaking the circuit.Plug fuses are inserted into a fuse holder and have a lever that you can pull to disconnect the fuse. They are typically rated between 10 and 30 amps.Reed fuses are similar to plug fuses but consist of a reed switch instead of a lever. When the fuse overloads, the reed switch opens, interrupting the circuit.

Selection of Fuses

When selecting a fuse for a circuit, it is important to select one that is properly rated based on the amperage that will be drawn by the circuit. Fuses are marked with their voltage rating and amperage rating. It is important that the fuse you select is rated for the same or higher voltage and amperage than what will be drawn by the circuit.

Working Principle of Fuses

Fuses are designed to detect electrical overloads and shorts. When an overload or short occurs, the fuse will blow or open, interrupting the flow of current and protecting the circuit.When the current drawn by the circuit exceeds the rated capacity of the fuse, the heat generated causes the metal strip(s) to melt or open. This interrupts the flow of current and prevents further damage to the circuit.Fuses are designed to only react to overloads and shorts and should not be used to protect against other forms of damage such as those caused by lightning.

Conclusion

Fuses are a vital part of any electrical system. They are used to protect circuits, equipment, and people from damage caused by overloading or shorting. Fuses come in a variety of forms and it is important to select one that is correctly rated for the circuit in question. Understanding the application field and working principle of fuses is the key to selecting the appropriate fuse for any application.
