Fuses: 0494002.NR Application Field and Working Principle

Fuses, such as the 0494002.NR, are able to offer a unique level of safety within many different industrial, commercial and residential environments. As such, they are used to protect against overcurrent and short-circuit conditions in a variety of electrical systems. The 0494002.NR is a single-pole, dual-element fusible disconnect switch. It is specifically designed for use in applications where high short-circuit ratings and interrupting capacities are required. In this article, we will provide an overview of the application field of the 0494002.NR and explain its working principle.

Applications

The 0494002.NR is designed to be used in AC and/or DC electrical circuits that involve a load with nominal voltage ratings up to 125V and interrupting ratings up to 200kA. It is particularly suitable for applications where high short-circuit ratings and interrupting capacities are required, such as protection of low voltage motor control centers, electronic equipment, multi-pole fusible disconnects, and certain types of lighting systems. It is also appropriate for applications in hazardous locations and is UL listed and CSA certified for use in the United States and Canada.

Working Principle

The 0494002.NR has a unique design that combines the functions of both a fusible disconnect switch and an overcurrent protection device. It has two elements: a movable contact and a fixed contact. The movable contact is made of a metal alloy which has a predetermined melting point. The fixed contact is designed to rapidly open when an overcurrent condition is detected.When a normal, non-overcurrent load is applied, the 0494002.NR operates as a standard switch. It connects the load and the power source, allowing the load to run as usual. When an overcurrent condition or a short-circuit situation is detected, however, the metal alloy in the movable contact is heated up until it melts, thus causing the contacts to separate and breaking the circuit. This makes the 0494002.NR a safe, reliable, and highly effective device for protecting against overcurrent and short-circuit conditions.

Conclusion

The 0494002.NR fusible disconnect switch is designed to offer a level of safety that is superior to that provided by regular switches. It has a unique design that combines the function of both a fusible disconnect switch and an overcurrent protection device. It can be used to protect against overcurrent and short-circuit conditions in a variety of AC and DC electrical circuits. It is suitable for hazardous locations and is UL listed and CSA certified.
