FNA-1-1/8

Fuses are a type of passive electrical device used to protect electrical circuits from excessive current and to prevent the possibility of fire due to overloads. Fuses are generally composed of a metal strip (fuse element) and a housing (fuse base) that contain it. Fuse elements are designed to melt when a specified current passes through it, breaking the circuit. One of the most common types of fuses is the FNA-1-1/8, which is used for applications in both residential and industrial settings. This article will discuss the application field and working principle of FNA-1-1/8 fuses.The FNA-1-1/8 fuse is a type of Class RK5 fuse, which is typically used in residential and light commercial applications. It is designed to provide protection against circuit overloads in applications such as residential lighting, air conditioning, refrigerators, and other high-current equipment. The fuse has a dual-element design which ensures higher switching capacity. The fuse element is composed of nickel and ferrous alloy, and is mounted on a body made of ceramic material. The fuse has a load limit of 20 amps, and a voltage rating of 600VAC or 250VDC.The FNA-1-1/8 fuse is designed to protect circuits against short-circuits and overloads, which can lead to catastrophic failures or fires. In the event of a short-circuit, the fuse element melts, breaking the circuit and protecting the downstream equipment from damage. The melting of the fuse element also creates an arc which rapidly clears out any current that was being drawn by the circuit. This helps to prevent further damage to the system.In the event of an overload, the fuse opens the circuit when the current drawn by the circuit reaches the rated limit. This helps to protect the circuit and the connected equipment from melting due to excessive current. When an overload occurs, the fuse element slowly melts due to the higher current, creating an arc which dissipates the energy and quickly clears out any current that was drawn by the circuit.The FNA-1-1/8 fuse is a versatile solution and can be used in a wide range of applications such as residential lighting, air conditioning, refrigerators, and other high-current equipment. The fuse is UL-listed and CSA-certified, and is designed to meet the highest standards of safety and reliability.In summary, the FNA-1-1/8 fuse is a type of Class RK5 fuse, which is typically used in residential and light commercial applications. It is designed to provide protection against short-circuits and overloads, and has a dual-element design for higher switching capacity. The fuse element is composed of nickel and ferrous alloy, and is mounted on a body made of ceramic material.
