Fuses are electrical protection devices, they are designed to respond to excessive current and create an open circuit, thus preventing the current from flowing to the protected circuit. The 0468002.NR application field and working principle are intended as an overview of the most common types of fuses and their applications.

The 0468002.NR fuse is a type of time-delay fuse. This means that it is designed to open the circuit if it senses an over-current condition for a given period of time. It is commonly used in applications where an immediate shutoff is not desirable or where frequent shutoffs would cause unnecessary strain or wear on other components. These types of applications include motor circuits, domestic and industrial lighting circuits, and amusement parks.

The working principle of a time-delay fuse is quite simple. It consists of two components: a sensing element, and an igniting element. If the sensing element detects an over-current condition, the igniting element will be triggered to open the circuit, thus protecting the circuit. The igniting element is typically made of special material, such as a pyrotechnic material, which ignites when exposed to a certain amount of heat.

The 0468002.NR fuse has a temperature rating of 138°C, meaning that it can handle up to 138°C before it will open the circuit. The current rating of this fuse is 10A, which makes it suitable for low and medium power applications. It is tin-plated, making it corrosion resistant and easier to solder. The size of the fuse is 5mm by 20mm, making it suitable for most circuit boards.

The 0468002.NR fuse is typically used in many applications, including lighting systems, HVAC systems, motor controllers, and circuit protection systems. It is often used in applications where a fast acting fuse is not desired, such as motor controllers, where it is desirable to keep the motor running until the over-current condition stops.

These type of fuses are also commonly used in domestic and industrial lighting systems, to ensure reliable protection against overcurrents. The ability of the 0468002.NR fuse to respond to an overcurrent within a set period of time makes it ideal for such applications, as it gives the lights an adequate amount of time to cool down before the fuse trips. It is also used in many amusement parks, to protect the circuits controlling the lighting and ride mechanisms from overcurrents.

In summary, the 0468002.NR is a time-delay fuse, designed for applications where a fast response is not necessary. It is a low and medium power fuse, with a temperature rating of 138°C and a current rating of 10A. Its size makes it suitable for most circuit boards, and it is commonly used in applications such as lighting systems, HVAC systems, motor controllers, and circuit protection systems.
