Cooper Bussmann FNQ-R-25 Time-Delay Fuse Class CC

The Cooper Bussmann FNQ-R-25 is a Class CC time-delay fuse rated for 600 VAC and 25 A, identified by model FNQ-R-25 and SE #332881. As a TRON time-delay fuse, it provides overcurrent protection for electrical circuits while tolerating brief overloads, reducing nuisance trips in loads that experience transient surges. Time-delay fuses are designed to handle short-duration overloads—such as startup currents—without tripping, making the FNQ-R-25 suitable for AC circuits that require dependable protection with temporary current spikes. The Class CC format supports standard protection assemblies and the Cooper Bussmann lineage ensures compatibility with CC-series holders and common protection schemes for circuits up to 600 volts. Verified specifications include a 25 A current rating, a 600 VAC maximum voltage, and the FNQ-R-25 designation within the TRON product family, with SE #332881 serving as the safety/compliance reference for this unit.
