FNA-1-8/10 is a type of electrical specialty fuse. It is a current-limiting device with the ability to prevent short circuits or overloads in electrical circuits. FNA (Fast Acting) fuses are designed to quickly disconnect the circuit in case of an overcurrent or overload. The FNA-1-8/10 is designed to disconnect the circuit within milliseconds. It is also designed to be used in mechanical switches to control high current in the circuit.

The FNA-1-8/10 fuse is constructed with a metalized element and a fuseholder. The element is housed within a small canister that is made from either zinc or aluminum. The fuseholder is made of either metal or plastic and is designed to hold the fuse element in place. The element is made of a specialized metal that has an extremely low melting point in order to ensure the fuse disconnects the circuit quickly and safely.

The working principle of the FNA-1-8/10 fuse is based on Eddy current losses. As the current passes through the fuse element, it creates eddy currents which cause resistance and generate heat. The fuse element has a low melting point which causes it to melt when the eddy current losses reach a certain point. When the element melts, the electrical current is disconnected, thereby preventing any further damage.

The FNA-1-8/10 is used in a variety of applications. It can be used in car circuits, industrial machines, electronic circuits, and other areas where a fast-acting fuse is needed for protective purposes. It is also used as a thermal protector in mechanical switches. It is typically mounted onto a terminal block to provide protection against overload in circuits. The fuse can also be used to control the flow of electrical signals in low voltage applications.

In summary, the FNA-1-8/10 is an electrical specialty fuse. It is an effective and reliable current-limiting device and is designed to quickly disconnect a circuit in the event of an overcurrent or overload. The fuse works by creating eddy current losses which cause resistance and generate heat. When the current passing through the fuse element reaches a certain point, the fuse element melts and the circuit is disconnected. The FNA-1-8/10 is used in a variety of applications such as car circuits, industrial machines, electronic circuits, and other areas where a fast-acting fuse is needed for protective purposes.
