FAQs
The FNQ-R-1-4/10 is designed for line protection and small control circuits in industrial panels. Its time-delay, current-limiting characteristics help manage moderate inrush currents typical of transformers and control devices, while its 200 kAIC interrupt rating provides a strong safety margin. It is well-suited for branch circuits and compact enclosures.
Yes. The FNQ-R-1-4/10 is a time-delay fuse that handles inrush more gracefully than fast-acting variants. With a 1.4 A rating and a 200 kAIC interrupt rating, it safeguards downstream equipment during startup surges without nuisance tripping, making it suitable for small control transformers and other devices with short, high-current pulses.
Yes. This fuse is CE marked and RoHS compliant, ensuring European regulatory acceptance and reduced hazardous substances in assemblies. Built on a Class CC design with a 600 V rating, it aligns with standard safety and environmental requirements for industrial protection devices.
Key ratings include 1.40 A amperage, 600 V voltage rating, 200 kAIC interrupt rating, and a 12-second response time at 200% for verification under fault conditions. This combination supports reliable protection of lines, branch circuits, and small transformers in industrial controls.
Install the FNQ-R-1-4/10 with ferrule-end connections into properly rated terminal blocks or harnesses. Ensure polarity and enclosure clearances meet panel standards, and verify the fuse is correctly seated to avoid looseness. Use the standard installation practices for Class CC fuses and refer to the data sheet for mounting guidance.
