155.0892.5751

Fuses are an integral part of the electrical system. Specialty fuses are an important subset of fuses because they provide specific protection needed for specialized applications. The 155.0892.5751 is an example of a specialty fuse and is designed for use in industrial control systems. In this article, we will provide a discussion of the 155.0892.5751 application field and working principle.

Overview of the 155.0892.5751

The 155.0892.5751 is a standard size 4AG specialty fuse. It is a fast-acting, current-limiting fuse designed to interrupt high short-circuit currents in industrial applications where a large contact gap and discrimination are necessary.

It has a voltage rating of 480 VAC and is available in ratings from 5-35 Amps. The fuse has direct and indirect time/current characteristics. This allows for discrimination in closely-spaced parallel fusing systems where two or more low-voltage supplies are connected to the same electrical bus.

155.0892.5751 Application Field

The 155.0892.5751 is suitable for use in industrial control systems. It is also suitable for use in process control systems, machine tools and other industrial equipment. It is recommended for branch circuit protection in motor controllers, motor-operated tools and other applications where precision time delay and current limit capabilities are required.

The 155.0892.5751 also meets UL standard 248-14. It is suitable for use as branch-circuit protection on DC and AC marine circuits, as well as military aircraft and shipboard equipment.

155.0892.5751 Working Principle

The 155.0892.5751 is a fast-acting, current-limiting fuse. When current is flowing through the fuse, the fuse element will heat up and expand until it reaches its melting point. When the melting point is reached, the fuse element will snap open and interrupt the current.

The fuse has direct and indirect time/current characteristics which allow it to provide precise discrimination in closely-spaced parallel fusing systems. In addition, the 155.0892.5751 is a current-limiting fuse which limits the current that can flow through the fuse in the event of a short circuit. This helps to reduce the potential for damage to electrical equipment.

Conclusion

The 155.0892.5751 is a specialty fuse designed for use in industrial control systems. It has direct and indirect time/current characteristics which allow for discrimination in closely-spaced parallel fusing systems. In addition, the 155.0892.5751 is a current-limiting fuse which helps to reduce the potential for damage to electrical equipment. It is suitable for use in motor controllers, motor-operated tools and other applications where precision time delay and current limit capabilities are required.
