0194399120 - Bussmann FNQ-R-5 Limitron Class CC Time-Delay Fuse 600V 5A

Advanced Circuit Protection with Bussmann FNQ-R-5

The Bussmann FNQ-R-5 is a premium Limitron™ Class CC fuse designed to provide robust protection for industrial control circuits and transformers. Engineered by Eaton, this fuse combines time-delay characteristics with superior current-limiting capabilities, making it an essential component for maintaining the safety and reliability of high-voltage industrial machinery. With a 600V AC rating and a 5 Amp current threshold, the FNQ-R-5 is specifically built to handle the rigorous demands of modern electrical systems found in manufacturing and fabrication environments.

One of the standout features of the FNQ-R series is its ability to withstand high inrush currents. Control transformers and solenoids often generate significant spikes in current upon startup; a standard fast-acting fuse would blow immediately under these conditions, causing unnecessary downtime. The FNQ-R-5's time-delay functionality allows these temporary surges to pass while still providing rapid response to sustained overloads or short circuits. This balance ensures that your equipment remains operational without compromising safety.

Safety is further enhanced by the Class CC rejection feature. The physical design of the fuse includes a rejection tip that prevents it from being installed in standard fuse clips intended for lower-voltage or different-class fuses. This ensures that the correct voltage and interrupting rating are always maintained within the circuit. Speaking of interrupting ratings, the FNQ-R-5 boasts a massive 200,000A RMS symmetrical rating, meaning it can safely interrupt extremely high fault currents without rupturing or causing arc flashes, protecting both the equipment and the operator.

Constructed with a durable melamine tube and nickel-plated brass endcaps, this fuse is built to last in harsh industrial environments. Whether you are maintaining welding power sources, industrial control panels, or lighting circuits, the Bussmann FNQ-R-5 offers the reliability and performance professionals demand.
