FAQs
FNQ-R-1 uses ferrule end x ferrule end connections and a compact 1.5 in length with 0.41 in by 0.41 in cross-section, making it straightforward to fit into standard Eaton Bussmann series installations. The rejection-style design helps prevent mis-wiring, and its 12 sec at 200% overload response supports predictable protection during startup surges.
Key specs include a 1 A amperage rating, 600 V voltage rating, Class CC current-limiting construction, time-delay dual-element design, and a 200 kAIC interrupt rating. It is non-indicating and uses ferrule-end connections, with a 1.5 in length and standard packaging.
Yes. Its current-limiting, time-delay (dual-element) design tolerates startup surges and minimizes nuisance trips, which is critical for small control transformers and industrial control panels. The 600 V rating and 200 kAIC interrupt capacity provide robust protection for typical industrial circuits.
The FNQ-R-1 is CE Marked and RoHS Compliant, aligning with European regulatory requirements. This helps ensure compliance in regulated markets and supports global deployments in panel assemblies and control cabinets.
As a non-indicating fuse, replacement is straightforward during routine maintenance or after a fault event. The ferrule-end design allows quick replacement, and its compact dimensions fit crowded panels, reducing downtime during cabinet servicing.
