Eaton NON-7 Fuse - 50 kAIC, 250 Vac /125 Vdc, CE Marked
Part Number: NON-7
Quick Summary
Eaton NON-7 fuse provides reliable general-purpose protection for low-voltage circuits in control panels. This design minimizes nuisance trips and protects against inappropriate coordination issues in non-critical loads. Key features include CE Marking, Class H general-use, 7 A rating, and 50 kAIC interrupt capability. This combination supports scalable protection in control panels, machinery, and general electrical assemblies while simplifying procurement. By standardizing ferrule-end connections and Bussmann compatibility, the NON-7 reduces installation time and maintenance costs. Engineers appreciate the ferrule-end connections for quick, reliable terminations in crowded control cabinets. The 2 inch length and compact dimensions fit standard Bussmann holders, reducing the need for custom adapters. With standard packaging of ten pieces per pack, stocking and replacement planning becomes straightforward across manufacturing lines.

Ferrule-end connections enable quick, reliable terminations in dense control cabinets, reducing installation time and minimizing loose wiring that can cause heating and intermittent faults. This translates to lower labor costs and fewer field failures, supporting faster plant ramp-ups in automation lines. Application: control panels, equipment racks, and machinery with compact wiring layouts. Non-current-limiting design avoids nuisance trips during startup or load fluctuations, delivering predictable protection for non-critical circuits while reducing unnecessary downtime. Application: general protection in low-voltage control circuits across industrial equipment. A 7 A rating with 50 kAIC interrupt capability ensures protection without oversizing fuses, preserving control system responsiveness and extending component life in small control loops. Application: sensing circuits and compact control feeders. Compatibility with standard Bussmann ferrule-end terminations and common holders enables easy sourcing, interchangeability, and fast replacement across fleets. Application: maintenance programs and multi-site rollouts. Standard packaging of ten pieces per pack simplifies stocking, reorder points, and field readiness, lowering procurement overhead. CE Marked compliance supports regulatory readiness for EU installations, enabling consistent deployment across compliant control architectures. Application: European projects and cross-border manufacturing sites.

FAQs
The NON-7 uses ferrule-end x ferrule-end terminations with a 2 inch length, making it compatible with standard Bussmann holders and many panel-mounted fuse blocks. Ensure clean, square ferrules and proper crimping, then seat the fuse fully to avoid floating contacts. The standard packaging of ten pieces per pack supports quick stocking and fast replacements.
The NON-7 provides 50 kAIC interrupt capability at both 125 Vdc and 250 Vac. This means the fuse can safely interrupt a fault current up to 50 kiloamperes at those voltages, helping protect connected equipment and ensuring proper coordination with upstream protection devices in low-voltage control circuits.
Yes. It is a general-purpose, non-current-limiting Class H fuse rated at 7 A, designed for reliable protection of control panels, relays, sensors, and other automation components. Its non-current-limiting behavior makes it appropriate for loads where precise protection timing is less critical, while still preventing catastrophic faults.
This fuse is CE marked, indicating compliance with applicable EU safety standards. CE labeling supports regulatory acceptance in European installations and in facilities that require conformity to CE requirements. The Class H designation also aligns with common industry expectations for general-purpose Bussmann fuses in control applications.
Stocking 10‑piece packs standardizes procurement and reduces ordering complexity across sites. Ferrule-end terminations streamline installation and replacement, minimizing downtime during maintenance windows. The reliable 50 kAIC interrupt rating lowers the likelihood of nuisance trips in fault conditions, contributing to reduced maintenance costs and improved overall equipment uptime.
