Eaton NON-12 Class H Fuse - 12 A, CE Marked for 50 kAIC
Part Number: NON-12
Quick Summary
Eaton NON-12 Class H fuse is a general-purpose protection device for control panels and industrial equipment. It delivers reliable overcurrent protection in compact form, helping engineers save panel space and simplify sourcing. This CE-marked Bussmann series fuse aligns with Class H expectations, providing predictable performance in a wide range of installations. The non-current-limiting design means it behaves predictably in circuits with inrush or startup surges, reducing nuisance outages when paired with appropriate protection schemes. For procurement and maintenance, the 10-pack packaging, ferrule-end connections, and straightforward interchangeability translate into lower total cost of ownership and faster uptime in demanding environments.

FAQs
The NON-12 is a general-purpose, non-current-limiting fuse rated at 12 A with a 50 kAIC interrupt rating, designed for control panels, power supplies, and other general electrical protection needs in light-to-medium industrial environments. Its ferrule-end connections and compact form factor support quick, secure integration into Bussmann-compatible fuse blocks, helping reduce panel space and maintenance time.
As a non-current-limiting fuse, the NON-12 does not aggressively truncate inrush currents, which minimizes nuisance tripping in circuits with startup surges. This makes it suitable for systems where controlled startup is expected. It still provides robust fault protection with a 50 kAIC interrupt rating, ensuring safe interruption of short-circuit events when properly coordinated with other protection elements.
Yes, the NON-12 uses ferrule-end x ferrule-end connections, facilitating secure, tool-free installation in compatible fuse blocks. Its compact footprint (0.56 in W, 0.56 in D, 2 in H) supports dense panel layouts. Ensure correct alignment and tight ferrule connections to maintain rated performance and voltage integrity up to 250 V.
The NON-12 is CE marked, indicating compliance with European safety directives. It carries a 12 A amperage rating, a 50 kAIC interrupt rating at 125 Vdc and at 250 Vac, and a voltage rating of 250 V. Use it in circuits within these specifications, and in Bussmann Class H configurations that match your protection strategy.
Using the NON-12 in new equipment supports lower downtime due to robust, predictable protection and easy stocking with 10-fuse packs. The non-indicating design reduces front-panel maintenance needs, while the ferrule-end connections enable quick replacement in standard fuse blocks. The compact size and high interrupt rating contribute to safer fault clearance and a lower total cost of ownership over the equipment lifecycle.
