Datasheet - FNQ-30
High-speed protection at 3 A, 150 Vac/dc delivers rapid fault clearance, reducing component damage and downtime in motor drives and control circuits. Ferrule-end connections ensure secure, quick field wiring and consistent contact pressure, lowering installation errors and maintenance calls in panel builds. Certifications including UL Listed, CSA Certified, and CE RoHS compliance provide regulatory alignment for global projects and easier procurement across regions. The compact form factor (0.74 in length, 0.74 in width, 2.27 in height) and a 0.9 lb weight fit standard Bussmann enclosures, simplifying retrofit projects and spare-parts management. The non-indicating design decreases false signals, while external signaling options can be added via compatible control schemes to meet monitoring requirements.

FAQs
DFJ-3 uses ferrule-end terminations designed for quick, secure wiring in standard Bussmann panels. Use matching ferrule sizes and a proper crimp tool to ensure reliable contact pressure and minimum resistance. Verify enclosure clearance, provide proper ventilation, and follow NEC/IEC wiring practices. For consistent results, reference the official datasheet and use compatible ferrule terminals.
The DFJ-3 provides 3 A amperage and a 150 Vac/dc voltage rating, enabling fast interruption of fault currents in both AC and DC circuits. Its Class J construction supports standardized fuse applications, while a non-indicating design emphasizes compact protection. In practice, this translates to swift fault clearance for sensitive loads and reduced risk of collateral damage in control systems.
Yes, the DFJ-3 is suitable for many DC and AC circuits in motor drives at 150 Vac/dc with a 3 A rating. Engineers should assess inrush currents and trip characteristics for the specific drive to ensure compatibility. For critical drives, pair with proper panel design and consider external signaling if indicating status is required for maintenance workflows.
The DFJ-3 is UL Listed and CSA Certified, with CE marking and RoHS compliance. These certifications support global acceptance, safety and environmental standards, and simplify cross-border procurement. Always reference the latest certificates in procurement and quality documentation to ensure ongoing compliance for international installations.
Using the DFJ-3 can reduce downtime through rapid fault interruption and standardized Bussmann ferrule-term connections, lowering maintenance time. Its compact size simplifies stocking and replacement in spares kits. While it is non-indicating, external signaling options can be integrated to support preventive maintenance, contributing to a lower total cost of ownership over the equipment lifecycle.
