Bussmann Limitron FNQ-R Series Class CC Time Delay Fuse
The Bussmann FNQ-R-15 is a Class CC current-limiting time delay fuse from the Limitron FNQ-R Series. The rejection-type design (Class CC) prevents substitution of lower-rated fuses, ensuring the overcurrent protection system maintains its designed characteristics. The time delay feature provides protection that distinguishes between harmless inrush currents and genuine fault conditions.
Features
- Class CC rejection-type design prevents substitution of lower-rated fuses
- Current-limiting action reduces let-through energy during fault conditions
- Time delay allows motor startup and inrush currents without nuisance opening
- Rated for both AC and DC circuits
- Melamine tube body for durability
