FX0456

Fuseholders are an important part of electrical engineering. One of the most popular models is the FX0456. This fuseholder is highly versatile and can be used in a variety of applications to provide circuit protection. In this article, we\'ll take a closer look at the FX0456\'s application field and working principle.

Application Field

The FX0456 is a miniature fuseholder with a DIN-rail mount. It has a compact design that is suitable for use in industrial and commercial control panels. The holder also has a snap-on cover for easy installation and a molded plastic housing that provides extra protection. The FX0456 is designed for use with 5 x 20 mm fuses, which are a common size for industrial circuits. It can handle up to 10A of current and is UL approved for safety.

The FX0456 is ideal for use in a variety of circuits, including electronic circuits, general-purpose fuses, lighting circuits, and small transformers. It can also be used in motor control circuits, switchboards, and power supplies. The holder is UL rated for up to 600VAC and 250VDC, making it suitable for a wide range of applications.

Working Principle

The FX0456 has two contact points: a positive and a negative. These contact points are connected to the fuse, which is then connected to the circuit. When voltage is applied to the circuit, the fuse acts as a protective device by limiting the current through the circuit. If the current exceeds the rating of the fuse, it will heat up until it melts, thereby cutting off power to the circuit and protecting it from damage.

In addition to the contacts, the FX0456 also has a snap-on cover and internal terminals. The snap-on cover is designed to securely hold the fuse in place, while the internal terminals provide an additional layer of protection. By connecting the terminals to the positive and negative contacts, the holder can provide even more protection against short circuits, overcurrents, and other dangerous conditions.

Conclusion

The FX0456 is a reliable and flexible fuseholder that can be used in a variety of applications. Its convenient size and snap-on cover make it easy to install, while its molded plastic housing and internal terminals provide extra protection from short circuits and other dangerous conditions. With a UL rating for up to 600VAC and 250VDC, the holder is suitable for a wide range of applications, making it a versatile and cost-effective choice.
