Introduction to FMX-50 Fuse

The FMX-50 fuse is a mechanical-action, current-limiting fuse that provides reliable protection for medium and high voltage circuits and systems. This type of fuse is used in a wide range of applications, from industrial to residential and commercial applications. It is a self-extinguishing fuse that can be reset after it has blown and is a cost-effective solution for medium and high voltage applications.

Applications of FMX-50 Fuse

FMX-50 fuses are used in a variety of high voltage applications such as motor control centers, transformer stations, high voltage switchgear, and HVAC systems. This type of fuse is also widely used in low voltage applications such as residential and commercial panelboards, switchboards, and motor overload relays. The applications of the FMX-50 fuse include circuit protection of fixed and movable equipment, motor overload protection, and industrial process control. Additionally, the fuse is also used to provide short circuit protection for incoming and outgoing power circuits in an industrial facility.

Working Principle of FMX-50 Fuse

When the current that passes through an FMX-50 fuse exceeds the rated current, the fuse element melts rapidly causing the metal contacts of the fuse to break the circuit and limit the current. The FMX-50 fuse has a current-limiting action that significantly reduces the potential of dangerous arc flashes in the event of a fault.The FMX-50 fuse also has a thermal-magnetic action that provides protection against short circuit, overload, and locked-rotor conditions. The thermal-magnetic response prevents the fuse from blowing in the event of a small overcurrent situation, whereas the current-limiting action of the fuse quickly initiates the circuit protective action if the overcurrent is beyond the fuse\'s capability.

Other Features of FMX-50 Fuse

The FMX-50 fuse has several other features such as a main shutoff switch that can be used to trip the fuse and interrupt the circuit. This shutoff switch is spring-loaded and can be reset after the fuse has blown. Another important feature of this type of fuse is the positive action latching mechanism which prevents the fuse from having to be manually reset after a fault.The FMX-50 fuse also has an optimized design that minimizes arcing and flashover, providing better system reliability as well as improved safety. This type of fuse is available with various fusing characteristics to meet specific application requirements and is UL and CSA approved. Lastly, the FMX-50 fuse has a modular mounting platform that makes it easy to install and maintain.
