LA130URD72LI0550

Specialty fuses designed for electrical applications play a vitally important role in ensuring the safety of the people using them and of their expensive electronics. Such a specialty fuse is the LA130URD72LI0550, designed to provide protection to high-value electrical equipment from overcurrent, overload, and short-circuit events. Depending on the size of the fuse used, these specialty fuses can protect circuits carrying currents up to 30 amperes, with interrupting ratings of 14/10 kilovolts (kV).

The LA130URD72LI0550 is designed to be embedded within the circuit board or other electrical equipment that is to be protected. This fuse is composed of a ceramic tube that is pre-dipped with a ferrule on both ends; this ferrule is then laser cut and formed to accept the insulated wire ferrules. The tube is filled with a specialized non-organic thermally conductive material that includes conductive particles. To limit the current flow to the circuit, a pair of metallized contacts are pressed into the ferrule at each end of the tube. The fuse also includes a series of contact points inside the tube that facilitate the connection of the ferrules and complete the circuit.

When there is a high-current situation such as an overload, short-circuit, or overvoltage, current rapidly flows through the fuse. This causes the non-organic material inside the tube to rapidly heat up, transforming it into a liquid state and melting the metallic contacts. This process interrupts the current flow and prevents dangerous electrical arcs from developing. This molten plug then quickly solidifies and the fuse must be replaced before the circuit can be reconnected.

The LA130URD72LI0550 is recommended for use in 12, 24, and 48-volt circuits that require moderate to heavy-duty protection. With its wide range of capabilities and compact size, it is a convenient and cost-effective means of ensuring protection of electrical systems and their users. The fuse can be used within a variety of industries, including telecommunication systems, medical systems, and automotive applications, and it is even suitable for use in hazardous locations.

The LA130URD72LI0550 specialty fuses from Littel Fuse Electrical go a long way towards providing reliable and efficient protection to electronics across a wide range of applications. The fuse is reliable and economical, making it an excellent choice for shielding vulnerable circuits from dangerous and costly electrical events.
