Fuses are an important component of electrical systems. They protect circuits from excessive current, overvoltage, and heat damage. The MRF 400-BULK-SHORT is a high-performance fuse for medium-voltage applications. In this article, we will discuss its application field and working principle.

Application Field

The MRF 400-BULK-SHORT is a UL recognized, type F, current-limiting fuse. It is designed to protect medium-voltage circuits, such as those found in industrial facilities, data centers, and other environments. This fuse has a current carrying capability of upto 400A and voltage rating of upto 480VAC. The fuse is available in two versions - quick-breaking or slow-blow, depending on the application needs. It also comes in different ampere ratings: 5, 10, 15, 25, 30, 40, 50, 70, 80, 100, 120, 150, 200, 230, 250, 300, 350, 400A.

The MRF 400-BULK-SHORT fuse is typically employed in a wide variety of applications, including overcurrent protection of electrical motors, power distribution networks, appliance control circuits, and computer equipment. It is also used in the protection of transformers, generators, relays, surge suppressors, and other medium-voltage electrical fixtures. Furthermore, the fuse is UL listed for Type F fusing applications, ensuring that its performance meets the highest safety standards.

Working Principle

The MRF 400-BULK-SHORT fuse operates on the principle of ‘time-delay’ and ‘current-limiting’. It functions by limiting the amount of current that can flow through the circuit. When the current exceeds the set limit, the internal spring-loaded contacts of the fuse will open up, blocking the current and resulting in the circuit breaking. This will thus protect the circuit from any damage caused by excessive current.

The MRF 400-BULK-SHORT fuse provides adequate protection for different types of circuits. It has a fast clearance time, which makes it suitable for use in circuits which require fast response. Additionally, it has a high interrupting short-circuit current rating (Ics) and withstand rating (Wrr) providing superior performance and protection against short-circuits.

Moreover, the fuse is available with an optional waterproof enclosure, which makes it suitable for use in wet environments. The fuse comes in a variety of sizes, making it suitable for different types of applications. It is also designed to be tamper-proof and ensures that no unauthorized interference will occur. This added security further helps to protect the circuit from damage when exposed to high currents.

Overall, the MRF 400-BULK-SHORT fuse is a reliable and safe fuse for medium-voltage applications. Its high performance and various sizes make it suitable for a wide range of applications. It is designed to protect circuits from the dangers of excessive currents, overvoltage, and heat damage.
