FNA-25

FNA-25 is a type of specialty fuse widely used in industrial and commercial applications. Its purpose is to protect electrical circuits and equipment from damage due to short circuits and overloads. FNA-25 has a body size of 25 x 38mm with screw connectors for wiring and also features a resettable trip mechanism which allows the fuse to be reset without the need for replacement.

The working principle behind FNA-25 is based on the concept of thermal resetting. When a short circuit or overload occurs, the heat generated causes the fuse element to expand. This leads to a deformation of the internal components which in turn causes the circuit to open. Once this happens, the current flow is halted and the fuse element cools down and contracts, allowing the circuit to reset itself and resume normal operation.

The FNA-25 is a type of high interrupting rating fuse specifically designed to provide better protection against shorts and overloads in industrial and commercial applications. It is rated up to 65 Amps and can be used for both AC and DC currents. Another feature of the FNA-25 is its ability to be reset without the need to replace the entire fuse, thereby reducing the cost associated with downtime and repairs.

The FNA-25 provides reliable and effective protection against electrical overloads and short circuit currents. It can be used in a variety of applications such as industrial lighting, motors, drives, electrical control panels, and various other applications in the commercial and industrial sectors.

Overall, FNA-25 is a reliable and effective specialty fuse that offers superior protection against short circuits and overloads in a variety of applications. It is easy to install and although the cost of the fuse is slightly higher than other fuses, its ability to reset itself without the need for replacement makes it a cost-effective solution for protecting electrical circuits and equipment.
