Eaton NON-20 Fuse - CE Marked Class H Non-current Limiting
Part Number: NON-20
Quick Summary
The Eaton NON-20 fuse provides reliable circuit protection for general-purpose electrical panels and control circuits. Engineers often struggle with selecting fuses that balance protective speed, uptime, and replacement costs in demanding industrial environments. This Class H, non-current-limiting fuse is CE marked and rated for 20 A with a 50 kAIC interrupt rating at 125 Vdc and 250 Vac, supporting robust safety and reliability. For panel builders and maintenance teams, the compact ferrule-end design and standardized packaging simplify installation and spare-part management. Note that SIL or IP ratings are not specified for this item, so verify your application requirements against the datasheet. The 2 inch length and slim profile help maximize space and ease procurement in crowded control panels.

Feature: Amperage and interrupt rating of 20 A with a 50 kAIC interrupt rating at 125 Vdc and 250 Vac. Business Impact: Provides robust short-circuit protection with clear coordination for typical industrial loads, reducing unexpected downtime and equipment damage. Application: Suitable for general-purpose control panels and industrial machinery where a 20 A protection level is appropriate. Feature: Non-current-limiting (NON) design. Business Impact: Predictable fusing behavior that avoids unnecessary upstream current limiting, allowing inrush or startup conditions to proceed without premature fuse operation. Application: Applications where controlled inrush is expected, such as control relays and simple motor circuits. Feature: Class H with ferrule end x ferrule end connections. Business Impact: Easy, secure installation with standard ferrule terminations, enabling reliable contact and reduced field wiring complexity. Application: Panel wiring harnesses and compact control enclosures. Feature: Compact form factor (2 in length, 0.56 in width, 0.56 in height) and light weight (0.036 lb). Business Impact: Space-saving design supports dense panel layouts and simpler stocking with higher part density. Application: Modern control panels where space is at a premium. Feature: Packaging type Standard and Quantity 10. Business Impact: Streamlined procurement and predictable spares availability for maintenance cycles. Application: Warehouse stocking and field service readiness. Feature: Compliance and indications. Business Impact: CE Marked provides regulatory alignment for many global markets; non-indicating fuse reduces visual clutter in panels. Application: Panels requiring straightforward compliance and minimal status indicators.

FAQs
The NON-20 is designed for general-purpose protection in electrical panels and industrial control circuits. It carries a 20 A rating and a 50 kAIC interrupt capacity at 125 Vdc and 250 Vac, making it suitable for a wide range of control loads. Its ferrule-end connections simplify panel wiring, while its compact size fits crowded enclosures.
Key ratings include 20 A amperage, 50 kAIC interrupt rating at 125 Vdc and 250 Vac, voltage rating of 250 Vac / 125 Vdc, Class H classification, ferrule end x ferrule end connections, and a non-indicating status. The device measures 2 in in length with a 0.56 in width and height, and weighs 0.036 lb.
Yes, the NON-20 fuse is non-current-limiting. This means it does not aggressively limit the peak current during short circuits, allowing for safer coordination with upstream protection devices and less disturbance in circuits that require controlled inrush handling. It’s well suited for general-purpose protection in panels where fast, current-limiting action is not required.
Install the NON-20 fuse using ferrule-end terminations to ensure secure connections. With a 2 inch length and standard packaging, it fits typical panel rails and enclosures. Be sure to verify the panel space, torque specifications for ferrule connections, and proper labeling to maintain clear spare-part management and safety compliance.
The NON-20 fuse is CE marked, indicating compliance with essential EU safety standards. To verify ongoing compliance, consult the latest Bussmann/ Eaton data sheets and the RoHS tool for any updates. For field verification, cross-check the catalog number NON-20 against the datasheet and ensure your application aligns with Class H, non-current-limiting protection.
