Eaton NON-70 Fuse - General-Purpose Fuse - 50 kAIC @125 Vdc
Part Number: NON-70
Quick Summary
Eaton Bussmann NON fuse provides general-purpose overcurrent protection for industrial control panels. Many installers struggle to balance reliable protection with space and compatibility, leading to delays and rework. It carries CE marking and supports high interrupt ratings, including 50 kAIC at 125 Vdc and 10 kAIC at 250 Vac, making it suitable for medium-duty feeders and control circuits. This fuse aligns with Class H blade-end hardware and standard 5-pack packaging, helping procurement reduce stocking complexity while ensuring fast replacement during maintenance. For engineers and buyers, the combination of robust electrical performance and straightforward installation translates into shorter project timelines and improved panel reliability.

The NON-70 is a 70 A, non-current-limiting fuse from the Eaton Bussmann series with blade-end connections. This general-purpose protection device delivers consistent interruption behavior for a wide range of industrial control panels. Use it in general circuits across manufacturing lines, distribution panels, and motor control centers where reliable protection and easy replacement matter most. Non-current-limiting fuses avoid aggressive current interruption for fast-clearing faults, reducing nuisance trips and making protection coordination simpler with upstream devices. This translates to improved line uptime, lower maintenance costs, and fewer inventory surprises during repairs. The NON-70 is well-suited for general power feeds and control circuits in new equipment builds and retrofit projects. With an interruption rating of 50 kAIC at 125 Vdc and 10 kAIC at 250 Vac, the NON-70 provides robust fault clearance for high-energy systems. This performance supports feeders and MCCs that experience short circuits while protecting downstream components from damage. The 250 Vac / 125 Vdc voltage ratings align with common industrial power standards, ensuring safe operation across diverse applications. Blade-end x blade-end connections simplify installation in standard fuse holders and panel enclosures, reducing commissioning time. The Class H construction and non-indicating fuse indicator align with common maintenance workflows, allowing straightforward replacement during routine servicing. This compatibility, combined with Eaton's channel support, minimizes downtime and accelerates procurement. Packaging is standard: five fuses per carton, with CE Marked compliance to support regulatory requirements in international installations. The compact dimensions—5.88 in length, 1.06 in width and height—facilitate panel layout and wiring density. These design choices help electrical teams meet space constraints while maintaining expected protection levels. Moreover, the durable design supports long service life in harsh industrial environments. For engineers and procurement teams, the Eaton NON-70 fuse delivers reliable protection, fast replacement, and streamlined sourcing in a single SKU. In practice, you gain reliability, faster maintenance cycles, and clearer cost planning across projects.

FAQs
The NON-70 uses blade-end x blade-end connections designed for standard fuse holders and panel enclosures. Ensure compatibility with Class H hardware and confirm the fuse holder accepts 5.88 inch length devices. During retrofits, verify space availability in the panel and stock matching replacements to minimize downtime during maintenance.
Key specs include a 70 A amperage rating, non-current-limiting behavior, and voltage ratings of 250 Vac / 125 Vdc. Interrupt ratings are 50 kAIC at 125 Vdc and 10 kAIC at 250 Vac. It is CE-marked and ships as standard packaging of five fuses per bundle, with blade-end connections for quick installation.
Yes. The NON-70 is designed for general-purpose protection in panels, MCCs, and feeders. Its non-current-limiting nature makes it suitable where upstream coordination can accommodate its fault-clearing profile, while its 70 A rating supports sizable control circuits without unnecessary tripping in normal operation.
The NON-70 carries CE marking, aligning with European regulatory standards. It is a Class H fuse and is intended for general electrical protection in industrial environments. The packaging and documentation reflect standard Eaton Bussmann practices for compliance and traceability.
The 5-pack packaging simplifies stocking and reduces procurement cycles, while the blade-end design speeds replacement in the field. With reliable performance and predictable interruption, maintenance downtime is minimized, contributing to lower labor costs and improved system availability over the equipment lifecycle.
