Fuses are an important type of electrical protection equipment. They serve to provide electrical continuity by allowing current of specified magnitude to establish and pass through its metal conductor elements. Fuses come in various sizes, amperage ratings, and physical configurations, each designed for a particular application. S500-32-R fuses, in particular, are designed for non-residential switchgear and panelboard applications.

The S500-32-R fuse is an HRC fuse link manufactured with silver-tipped copper or silver or aluminum-alloyed solid metal elements. It is designed for use in switchgear, panel boards, and distribution systems. The fuse is available in sizes ranging from 0.3 to 50 amperes in three substrate options: fuse boards, ceramic body, and class CC. It is a dual-element, 32 kV rated fuse with an operating voltage of 30 kV.

The S500-32-R fuse works by passing current through its solid metal elements. When a current greater than the rated amperage flows through the fuse, the solid metal elements heat up and expand. If the current exceeds a certain level, the thermal expansion causes a physical separation of the elements. This separation interrupts the electrical connection and the current is blocked. The amount of current needed to cause the elements to expand and separate is called the system cut-off current.

The system cut-off current of the S500-32-R fuse is carefully calculated so that the instantaneous interruption of the electrical connection provides the desired level of protection. The S500-32-R fuse is designed to handle short-circuit currents as much as 25 times its rated amperage. The fuse will safely blow out any current exceeding the rated amperage, protecting the electrical equipment and components from damage.

The S500-32-R fuse has been designed to provide a high level of protection from over currents, short circuits, and other damages caused by electrical loads. It is a dependable and economical choice for non-residential switchgear and panelboard applications. The fuse is UL Listed, CSA certified, and meets IEC standards and requirements. The S500-32-R is available in various configurations and ratings to meet the needs of a wide range of applications.
