LA15QS1304 is an ultra-fast blow fuse manufactured for use in electrical applications. It is a specialty type fuse, designed to protect consumers and their appliances from dangerous over-currents or short circuits. Specifically, the LA15QS1304 has a fast blow operating time of 4 milliseconds or less. This makes it suitable for protecting sensitive systems against the risk of over-voltage.

The LA15QS1304 fuse features a rectangular cylindrical body and has a voltage rating range of 125V to 250VAC. The fuse also has an operational temperature range of -40°C to 85°C and an interrupting rating of 10,000A at 250VAC. It also features a current rating of 15A with a response time of ≤4ms, making it part of the UL248-14 recognized family of the Specialty Fuse application field.

The LA15QS1304 fuse is made using advanced ceramic technology and has a reliable construction, making it capable of providing high levels of protection. The fuse consists of a ribbon wire with a copper inner conductor and a ceramic outer conductor. The outer conductor also features a slow-blow lettering to denote the time-delay characteristic of the fuse. The fuses are coated with a hermetic material, ensuring that they remain sealed and secure from the environment and any added contaminants.

When it comes to the working principle of the LA15QS1304, it utilizes a special heat-sensitive material contained within the fuse link. In the presence of an over-current, the temperature of the fuse link increases, weakening the bond between the link’s metal layers and allowing the current to pass through more quickly. As a result, the fuse link breaks and the current is interrupted. Since this entire process takes only a few milliseconds, the fuse is able to provide effective and quick protection against over-currents and is particularly useful in the safeguarding of sensitive electronics.

Due to its fast blow response time, high current rating, and hermetic sealed construction, the LA15QS1304 makes a great choice for those looking for a reliable specialty fuse option. It is particularly well suited for the protection of sensitive electronics from over-currents and is easy to install and use, requiring no additional maintenance on the part of the consumer.
