Fuses serve an invaluable purpose; they are an invaluable line of defense against equipment malfunction or destruction due to short-circuiting or overloading caused by a variety of electrical surges. But not all fuses are created equal, and the 3JS 500-R TR has a lot to offer when it comes to providing protection in difficult applications. 3JS 500-R TR is a specially designed fuse from Siemens which meets the highest safety requirements for power-intensive applications, such as those found in used in heavy industrial plants with high-quality products.

The 3JS 500-R TR series is a three-phase fuse with a voltage rating of 500V AC/650V DC. It has a current rating of 32A with multi-pole configurations up to 16. It operates on a symmetric form which provides a high level of protection without any compromise in the reliability of the circuit.

The 3JS 500-R TR series is designed for three-phase applications such as motors, generators, transformers, line reactors, and other highly loaded electric applications in both residential and industrial settings. It is suitable for switching off and protecting against overloads in all circuits up to the maximum rated current, as well as providing short-circuit protection, making them an ideal choice for sensitive equipment in power-intensive applications. The fuse\'s design allows for a quick and reliable response during a short-circuit or overload event, preventing damage to equipment and providing optimal protection.

The 3JS 500-R TR series is housed in a two-piece, 1 inch by 1.6 inch UL-Rated enclosure with AC rated current ratings of up to 32A. This design ensures that the fuse body stays intact during a fault event and provides superior protection against shorts. It is designed to trip quickly when overloaded, typically within milliseconds, to prevent any damage to equipment.

The working principle of the 3JS 500-R TR series fuse is based on the reactive forces created by the heat and pressure generated by an electrical fault. When too much current exceeds the amperage rating of the fuse, it causes a build-up of heat which causes the fuse to melt. This results in an electrical arc which breaks the circuit, before reaching any harmful fault currents. This breaking of the circuit limits any potential damage caused by the fault current.

The 3JS 500-R TR series fuse’s superior protection and quick response time make it an ideal choice for those tough applications requiring the highest safety standards. Its two-piece construction ensures the fuse stays intact during a fault event, while its quick response time ensures any short-circuits or overloads are caught quickly, limiting damage to equipment.
