The 200NHM2B-690 is a type of electrical component specifically categorized as a specialty fuse. Fuses are devices used to protect electric circuits from excessive overloads, short circuits, and other dangers. These specialty fuses offer enhanced protection for specific road applications. In this article, we will discuss the 200NHM2B-690 application field and working principle.

The 200NHM2B-690 is designed for use in industrial, lighting, and commercial applications. It is able to provide protection against high levels of current, short circuits, and other common dangers caused by effects such as transient overvoltage. This fuse is typically used as circuit protection in secondary distribution networks and in other high-energy environments. Moreover, they are often found in emergency lighting systems and undervoltage fault protection circuits, as well as in low-voltage motor regulation systems.

In order to properly use the 200NHM2B-690, it is important to understand its working principle. This fuse is composed of a thin metal ribbon, typically made of silver, linked to a ceramic body by two terminals. The ribbon is placed under tension and is the primary element of the fuse. When the current reaches a certain pre-set limit, the metal ribbon heats up and melts, thereby breaking the circuit and preventing further damage.

The 200NHM2B-690 is a fast-acting fuse designed for the highest level of reliable protection. It is UL-approved and has an interrupt rating of 500A @ 8.0Vdc. This type of fuse features a low current-time characteristic, allowing it to trip faster than other fuses. Furthermore, it is capable of handling a wide range of voltage and current levels. The 200NHM2B-690 boasts anti-tracking technology to help limit the risk of arc flash.

The 200NHM2B-690 is an ideal solution for those looking for a reliable and efficient line of protection in industrial, lighting, and commercial applications. With its high-quality construction and UL approval, it offers reliable protection from short circuiting and other dangerous electric effects. Additionally, its fast reaction time and low current-time characteristics make it a great choice for both low and high-energy environments.

To conclude, the 200NHM2B-690 is a highly functional specialty fuse that offers reliable protection in industrial, lighting, and commercial settings. This fast-acting fuse is composed of a thin ribbon that melts when the current levels become too high, thus breaking the circuit and providing protection. With its UL-approval and anti-tracking technology, it is a secure and efficient solution for a number of industry applications.
