Electrical, Specialty Fuses

JJN-500 is low voltage electrical fuses designated for use in special environments. Some of the key environment where JJN-500 offers unique advantages include, but not limited to, power system protection, marine, rail, mining, telecommunications, industrial control, and HVAC applications. The main function of JJN-500 is to protect against shocks, low-voltage circuits, and the overloading of current.

The JJN-500 fuses are available in a wide range of sizes and ratings (measured in amperage). Their small size and low profiles are made possible through advanced fuse technology. The JJN-500 fuses are extremely reliable and offer exceptional protection for equipment and circuits.

At its core, the JJN-500 device is made up of two components: a fuse element, and a metal casing. The fuse element is an enveloped wired fuse and is placed inside an insulated metal casing that consists of a base, cap, and other components. This combination helps to provide the circuit with reliable protection, while also allowing for easy installation and replacement.

JJN-500 devices work in the following way – the fuse element is “blown” when a short circuit or an overload occurs in the circuit. This causes the wire inside the fuse element to evaporate and open the circuit to prevent further damage. Once the short circuit or overload is resolved, the unit can be reset with the help of a reset lever on the side of the device.

The JJN-500 fuse offers a variety of advantages for users. For one, they are designed to fail safely before a major component is damaged, which can save users from expensive repairs or replacements. Additionally, these fuses provide accurate rating, making them suitable for circuits of all voltages. And lastly, JJN-500 offers superior resistance against shock and vibration.

Today, JJN-500 fuses are an essential part of many industries, including marine, rail, mining, telecommunications, power system protection, industrial control, and HVAC. They are becoming increasingly popular due to their reliable protection, excellent resistance to shock and vibration, accurate ratings, and small size.
