The JJN-350, an electrical specialty fuse, is designed to serve as a safety device. It is used in high voltage applications to protect circuits from excessive current by breaking the circuit when it exceeds the maximum level permitted. The greater the current, the faster the fuse will blow.

The JJN-350 fuse has a rating of 350A at 250V. This means that it will not blow until the circuit current reaches 350A or greater. It also has a fast response time, which means it is capable of breaking the circuit very quickly when the current level rises above the maximum allowable value.

The fuse body is composed of a metal tube with brass ends, which houses the fuse element. The fuse element is usually a small piece of metal that melts when the current level is exceeded. This melting action causes the circuit to break and the fuse to blow. The metal end caps, which are secured to the body with screws, insulate the fuse element from the circuit.

The contact terminals on the end caps of the JJN-350 fuse are designed to open when the fuse element melts. This prevents any further current from flowing, thus protecting the circuit. The contact terminals provide direct connection points for attaching the wires. Once the circuit is disconnected, the contacts remain open and prevent any current from flowing.

The JJN-350 fuse is designed to be used in a variety of applications such as lighting circuits, home entertainment systems, computers, and electrical equipment. It is suitable for protecting equipment from over-current, short circuit, and other electrical faults. It is also suitable for motor driven devices, which use powerful motors that can draw large amounts of current.

The JJN-350 is made with a glass-fiber reinforced casing and is corrosion resistant. The fuse also features a wide clearance between the contact points, which ensures proper shielding of the circuit. The wide clearance also allows for the fuse to be safely removed from its enclosure without fear of electric shock.

The JJN-350 fuse is easy to install. The end caps can be unscrewed and the fuse can then be installed in the required location. The contact terminals are color-coded for easy identification and the body is labeled with its rating. The fuse is also made with a non-reversible design, so that it can only be inserted and removed from the correct direction.

In summary, the JJN-350 is a reliable electrical specialty fuse that is suitable for applications requiring high current protection. It is easy to install, corrosion resistant, and has a wide clearance between the contact points. This makes it an ideal choice for protecting electrical circuits from over-currents and short circuit faults.
