Electrical components such as circuit breakers, fuses, and other safety devices help protect home and building structures from dangerous electrical currents. Fuses, in particular, provide a simple yet effective way of protecting vulnerable electrical systems and components from potential damage or destruction due to electrical overloads. FNQ-R-1-8/10 speciality fuses are standard IEC fuse range with high interrupting capacity and high current rating. This type of fuse is capable of breaking short circuit currents far greater than a conventional fuse, thus providing high-level protection for a variety of electrical applications.

FNQ-R-1-8/10 fuses are commonly used in both residential and commercial applications. As a standard IEC fuse, the FNQ-R-1-8/10 can be used in a wide range of application fields including but not limited to motor starting, motor control, small motor control, and electronic equipment protection. It offers superior protection against over-currents and short circuit conditions.

The FNQ-R-1-8/10 utilises a time-delay fuse element that allows for lower arcing levels and higher interrupting capacity. This fuse consists of a fusible element, spring and a fuse link embedded in a polycarbonate tube. The fuse link is composed of a copper alloy strip or wire that has been designed to melt and disrupt the flow of electricity when the electricity exceeds the fuse rating. The polycarbonate tube serves as an isolator and helps to prevent the arc from phosphorising the contacts.

When the current exceeds the rated value of the fuse, the metal strip or wire melts, causing the fuse element to open and interrupt the flow of electricity. The spring located inside the fuse helps to re-establish the contact after the fuse has cooled down and the current returns back to normal. It also helps to absorb the impact of electricity when the fuse is opening, thus allowing the interrupt rating to be greater than other fuses. The FNQ-R-1-8/10 also offers a greater margin of safety than other fuses due to its higher interruption of current and lower arcing levels.

The FNQ-R-1-8/10 has a current rating from 8 to 10 amps and a voltage rating up to 600 volts AC and 42 volts DC. It is UL, CSA, and IEC approved and features a quick-response time delay. This type of fuse is designed to provide high safety standards and low arc distortion levels to protect electrical components from damage due to excess current.

In summary, the FNQ-R-1-8/10 is a specialty IEC fuse that provides superior protection against electrical overloads and short circuits, even those causing high currents. It is designed to provide a higher level of safety than other fuses due to its higher interrupting capabilities and lower arcing levels. This fuse is suitable for a wide range of applications from motor starting to motor control, small motor control, and electronic equipment protection.
