LFH254003C Application Field and Working Principle

Fuseholders are essential components in various electrical circuits and devices, ranging from household appliances, power systems, automotive parts, and even aerospace and industrial equipment. In particular, LFH254003C type holders are commonly used for mounting fuse-type miniature circuit breakers (MCBs) into panels, switchboards, or other enclosures.LFH254003C holders are designed around two main components: an off-the-shelf fuse body, and a female-type holder. The idea behind this design is to enable the user to mount the holder onto a panel, switchboard, or similar installation. This design eliminates the need to source and install threaded fuse holders, and can be used with a number of size-appropriate MCB fuses.This type of holder is suitable for use with various fuses and circuit breakers, such as NF Series Vacuum Interruptor Fuse Links, NP Series Electric Furnace Fuse Links, or VB/VG NANO Series Plug-in Thermal Fuse Links. It can also accommodate a wide range of other size-appropriate MCB fuses, such as the LFH254003C-Int, LFH254003C-CC, and LFH254003C-EIC versions.LFH254003C holders feature a 6/2mm fuse body with a female holder made of transparent polycarbonate. The female holder is designed to fit directly into the back of the fuse and hold it in place. The female holder also features two circular contact surfaces, which allow current to flow unimpeded from the fuse to the equipment that the fuse is protecting.When installing a LFH254003C holder, the installer starts by making sure that the panel, switchboard, or other installation is clean. Once the panel is clean, the installer attaches the female holder to the panel so that it is securely fastened. The installer then attaches the fuse into the body by inserting it into the female holder. After that, the installer re-tightens the female holder by twisting it in a clockwise direction. The body is then attached to the equipment, such as a panel, switchboard, or similar installation.The working principle of LFH254003C holders is simple. When the electric current in the protected equipment reaches a certain level, the fuse melts and cuts off the circuit. This prevents any further damage to the equipment due to an overload or short circuit.Overall, LFH254003C holders are a reliable and economical way to mount MCB fuses and circuit breakers into panels, switchboards, and other installations. With its simple, two-part design and wide compatibility with various fuse sizes, the LFH254003C holder is an excellent choice for a range of applications.
