FNA-25~FUSETRON DUAL ELEMENT
Datasheet - FNQ-30
Time-delay and dual-element construction provide controlled responses to inrush and load surges rather than immediate fuse opening. This design minimizes nuisance trips during motor start-ups and solenoid energizations, while preserving protection against sustained overloads. As a result, you gain higher equipment uptime, fewer process interruptions, and reduced need for fuse replacements in high-cycle panels. The FNA-25 is especially well-suited for control panels, conveyor drives, and distributed automation nodes where reliable startup behavior matters. Amperage rating of 25 A paired with a 1 kAIC interrupt rating at 32 V ensures robust protection without unduly compromising startup performance. The fuse tolerates short overloads common with motors and solenoids, reducing nuisance trips while preserving circuit protection. This makes it a dependable choice for low-voltage DC/AC circuits in industrial automation. Silver-plated pins deliver reliable connections that resist corrosion and maintain low contact resistance over many mating cycles. The dual-element configuration further enhances reliability in vibrating or temperature-fluctuating environments, while the compact 1.5 inch length and standard packaging support straightforward installation in crowded panels and assemblies. This combination translates to longer service intervals and lower maintenance costs for mission-critical equipment. Regulatory compliance is straightforward with CE marking and RoHS compliance, enabling easy procurement for global projects. The standard packaging simplifies stocking and replacement in multi-line facilities, while the non-indicating fuse style reduces visual clutter in aligned applications. The 32 V rating aligns with typical control-system voltages, reducing overvoltage risk and enabling safer, more predictable operation across machines. In practice, the Bussmann FNA family delivers superior overload and cycling capabilities, aligning with common industry needs in electrical protection and circuit control. End users benefit from improved uptime, easier spares management, and a clear path to regulatory compliance in international deployments. With 25 A, 32 V, and 1 kAIC ratings, the FNA-25 provides a balanced, durable solution for modern automation environments.

FAQs
The FNA-25 is designed for 32 V control circuits and supports both AC and DC applications typical of low-voltage industrial panels. With a 25 A rating and 1 kAIC interrupt capacity, it fits standard protection schemes in control cabinets, motor controllers, and solenoid drivers while offering straightforward mounting and connection via its silver-plated pins.
Time-delay means the fuse tolerates short overloads, such as motor inrush, without tripping immediately. The 1 kAIC interrupt rating ensures quick interruption for sustained faults, while the 25 A rating accommodates normal operating currents. This balance minimizes nuisance trips during startup and maintains circuit protection for motors and solenoids in automation systems.
Ideal applications include control panels, conveyor drives, motor controllers, and other inductive loads in industrial automation. Its 32 V rating suits electrical protection and circuit control architectures in factory equipment, and its standard packaging simplifies stocking and replacement in multi-line facilities.
The FNA-25 is CE marked and RoHS compliant, signaling regulatory alignment for European and global deployments. These certifications help ensure compliant sourcing, reduce risk in international projects, and facilitate smoother procurement and installation across multinational sites.
With silver-plated pins and a dual-element design, the fuse offers durable connections and reliable cycling performance, reducing maintenance visits and spare-part usage. The combination of time-delay protection and robust interrupt rating translates to higher uptime, lower downtime costs, and predictable lifecycle costs in high-demand automation environments.
