025101.5NRT2

Fuses

025101.5NRT2 is a class of fuses designed for protecting circuits and components from overload and short circuit damage in industrial, commercial and residential applications.

Application Field

These fuses are most commonly used in home electric appliances such as washing machines, air conditioners and water heaters, but also extended to serve panels, transformers, motors, lighting, and commercial and industrial establishments. All fuse sizes are available in universal sizes suitable for North America, Europe, Asia, Australia and other places.

025101.5NRT2 fuses also provide protection against electrical spikes. An electrical spike is an unexpected surge of electrical current in a circuit. It can occur when a greater than expected current attempts to flow through the circuit from an external source. Electrical spikes usually last a very short period of time and can often damage electrical equipment and components if left unchecked.

025101.5NRT2 fuses also provide protection against overloading. Overload protection is intended to prevent overheating of an electrical circuit due to excess current draw. An overload occurs when more current is drawn from a circuit than the circuit can safely handle. This can be caused by electrical components that produce too much heat, resulting in a fire hazard if the circuit is not protected.

Working Principle

A 025101.5NRT2 fuse contains a metal alloy element, usually a silver and copper wire, inside a glass tube. When too much current is drawn through the circuit, the metal alloy element will quickly heat up and melt, breaking the circuit and preventing further damage to the components. The metal alloy element has to have the right temperature and melting point in order to correctly protect the circuit.

The fuse has connecting terminals at both ends. When the metal alloy element is heated, it breaks the connections between both terminals, thus interrupting the current. Once the current is shut down, the fuse will reset, allowing current to pass through the circuit again. In this way, the fuse continuously protects the circuit from possible overloads.

When replacing a fuse, it is important to use one of the same rating and type as the one being replaced. If a fuse is used that is too large or too small, it may not provide the needed protection to the circuit. Additionally, the fuse should be inspected for signs of damage, such as a blown fuse element or discolored contacts.

In conclusion, 025101.5NRT2 fuses are designed for protecting circuits and components from overload and short circuit damage. They have a metal alloy element inside a glass tube, that when heated, breaks the connections between both terminals, thus interrupting the current. They are commonly used in home electric appliances, industrial and commercial establishments, and provide protection against electrical spikes and overloading.
