Fuses are electrical components designed to protect against surge, overload, and short circuit conditions in a variety of electrical circuits, including automotive, industrial, telecommunications and consumer electronic applications. They work by melting and breaking an internal filament when a specified current flows through it, thereby interrupting the circuit.

SSQ 7/5K fuses are a special variation of fuses designed for higher capacity and increased current-carrying capacity up to 500Vdc. The SSQ 7/5K uses a high-temperature quartz filament with a fuse body made of stainless steel and porcelain.The fuse elements can be configured as a single element or multiple elements to meet design application requirements. SSQ 7/5K fuses are ideal for applications in high-end, high-power, and high-amperage circuits.

The SSQ 7/5K fuse is designed to protect against excessive current or short circuits, and will blow when a specific current level is exceeded. It is composed of two pieces, the fuse itself and the end caps. The fuse contains the stainless steel and porcelain body, which houses the quartz filament in the center. The end caps secure the fuse elements in place. The fuse is rated for 500Vdc, and has an interrupting rating of 9.5kA/sec.

The working principle of the SSQ 7/5K fuse is based on the theory of electrical resistance. When an overcurrent is passed through the fuse, the small quartz filament inside heats up and melts. This causes an open circuit in the circuit being protected, interrupting the current flow and protecting the circuit from overload and short circuit damage.

SSQ 7/5K fuses are designed for reliable operation in high-power and demanding electrical applications, such as in high-voltage high-capacity switchgear, data centers, telecommunications networks, and consumer electronic equipment. It provides protection from overvoltage, overload and short circuit conditions. SSQ 7/5K fuses are UL listed and CSA certified, providing peace of mind knowing that the application is protected with the highest quality components.
