Fuses - 0679H2000-01 application field and working principle

Fuses are safety devices used in homes and businesses to protect electrical circuits. They will melt or “blow” if the current exceeds a predetermined value, thus preventing a hazardous condition. The 0679H2000-01 is a type of fuse, and its application field and working principle are discussed in this article.

Application Field

The 0679H2000-01 is an ideal fuse for use in a variety of applications. It is a low-voltage, melting element fuse designed for use with devices wired to direct current (DC) circuits of 24 Volts or less. It is particularly suitable for use in American circuit systems where incoming current is limited to 15 Amps.

Applications typically include in-line circuit protection for DC systems and devices such as line filters, motors, control panels, and circuit boards. With a current limitation range of 4-15A and a miniature size, the 0679H2000-01 offers high performance and versatility for a variety of circumstances. It is both UL listed and RoHS compliant, lending extra confidence in its quality.

Working Principle

The 0679H2000-01 utilizes a cylindrical melting element made of an alloy material. When current flows through the 0679H2000-01, it produces a specific amount of heat, which is directly proportional to the current passing through it. In normal use, this heat is dissipated into the surrounding environment. What happens to the fuse when the current flowing through it exceeds its rating is that the heat produced inside the fuse is greater than the amount of heat that can be dissipated into the air, so the core of the fuse melts and breaks the circuit, thus protecting the equipment connected to it.

One of the unique features of the 0679H2000-01 is its linear characteristics. Unlike other types of fuses, the 0679H2000-01 is designed to have a linear melting characteristic. This means that when the current exceeds its threshold, it will not instantly trip, but rather it will progressively increase the trip current, allowing easier identification of the actual cause of the trip. This is in contrast to a general purpose, non-linear fuses, which will simply trip regardless of whether the current is above or below its rating.

Overall, the 0679H2000-01 is a reliable and cost-effective solution for protecting devices in DC circuits of 24V or less. It is robust, easy to install and standard-compliant, so it is suitable for a variety of professional AC/DC applications. It is also small and lightweight enough to be used in portable applications, making it a great choice for many different scenarios.
