FAQs
Install the FNA-1-1/2 with ferrule-end terminals, ensuring a snug, secure connection to the wiring harness. The unit’s compact 0.35 in square footprint and 1.46 in length fit standard control panels; verify correct amperage rating of 1.5 A and a 250 V supply. Ensure clearance for airflow and follow panel wiring practices to minimize contact resistance and heat build-up.
This time-delay dual-element fuse is intended for inductive loads and electronic circuits. It excels at motor starters, transformers, solenoids, and similar loads where brief inrush occurs, preventing nuisance trips while maintaining circuit protection in automation and control panels.
The fuse is rated for 1.5 A at 250 V with a high interrupt capability of 200 kAIC at 250 V and 10 kAIC at 125 V. These ratings provide robust protection against short circuits while accommodating typical inductive load behavior in industrial applications.
Yes, the FNA-1-1/2 is CE marked, signaling conformity with applicable EU safety standards. This helps streamline procurement for European equipment and ensures compatibility with European electrical protection practices in control panels and automation cabinets.
The fuse features ferrule-end terminations on both ends, with a cross-section of 0.35 in by 0.35 in and a length of 0.35 in for the body, plus a height of 1.46 in. This compact footprint supports installation in tight spaces and simplifies replacement in existing Eaton Bussmann installations.
