FAQs
To install the FNQ-30, align the ferrule-end connections with the busbar or control circuit terminals designed for ferrule-end fuses, secure with appropriate hardware, and verify the endcaps are fully seated. Confirm panel labeling matches FNQ-30 catalog data and ensure supply voltage is within 500 V. This approach minimizes contact resistance and ensures reliable protection for motor circuits.
Key ratings for FNQ-30 include a 30 A amperage rating, a 10 kAIC interrupt rating at 500 Vac, and a 500 V voltage rating. These specifications define the fuse's capacity to interrupt faults quickly while tolerating normal startup surges, making it suitable for motor control circuits and other low-voltage protective applications.
Yes. The FNQ-30 is designed as a time-delay fuse, specifically for circuits with inrush currents such as motor starters and control transformers. Its delay characteristic reduces nuisance trips during startup, helping maintain production uptime while protecting conductors, contactors, and downstream devices from overcurrent events.
The FNQ-30 is CE marked and RoHS compliant, signaling conformity with European safety requirements and restricted substance regulations. These certifications support regulatory audits and customer compliance programs, particularly for machinery builders and integrators operating in regulated markets.
The FNQ-30 reduces downtime by mitigating nuisance trips and extending motor life through controlled startup protection. Its durable nickel-plated bronze endcaps and standard packaging simplify field replacements and stocking, lowering maintenance labor, spare parts costs, and overall lifecycle expenses for industrial installations.
