Eaton NON-450 Fuse - Class H, CE Marked, 450A
Part Number: NON-450
Quick Summary
Eaton NON-450 fuse provides reliable general-purpose protection for electrical panels and machinery power circuits. Engineers often wrestle with selecting a high-capacity device that fits in tight spaces without compromising fast, predictable interruption. This CE-marked Class H fuse offers a 450 A rating with a 10 kA interrupt rating at 250 VAC, delivering robust protection. By combining standard packaging with a compact footprint and non-indicating indicators, it reduces maintenance time and simplifies spare part inventories. In practice, contractors gain uptime and compliance confidence in industrial panels, switchgear, and motor control centers.

Bussmann series Class H (K) Fuses Data Sheet no. 1030
Feature: High amperage rating and large interrupt capability. Business impact: Enables protection of heavy-load circuits up to 450 A with a 10 kAIC interrupt rating, reducing conductor damage during faults. Application: Motor feeders, power distribution panels, and switchgear in demanding industrial environments. Feature: Non-current-limiting, non-indicating fuse design. Business impact: Simplifies sourcing and stock planning while delivering straightforward fault interruption without inrush suppression, ideal where inrush is acceptable. Application: General-purpose protection in standard controls and distribution panels. Feature: Class H designation and Bussmann Series compatibility. Business impact: Facilitates easy substitution within Eaton/Bussmann ecosystems and reliable replacement cycles without custom hardware changes. Application: Retrofit projects and new panel builds expecting proven Class H fuse performance. Feature: Physical footprint and packaging. Business impact: 10.38 inch length with a compact 2.59x2.59 inch profile and 2.68 lb weight fits common enclosure spaces while standard packaging speeds on-site stocking. Application: Enclosures with limited depth or width and standard fuse holders. Feature: Compliance and lifecycle clarity. Business impact: CE Marked assurance supports EU compliance and decreases risk during audits, while the one-time fuse design clarifies maintenance intervals. Application: Industrial control panels requiring clear regulatory adherence.

FAQs
The NON-450 is a Class H, non-indicating, one-time fuse with a length of 10.38 in and a footprint of 2.59 by 2.59 in. Plan for standard packaging and compatible Bussmann/Class H fuse holders in 250 V circuits. Ensure proper enclosure clearance and replace with an identical model after operation to maintain safety and ratings.
Key ratings are 450 A amperage, 250 V voltage, and a 10 kAIC interrupt rating at 250 VAC. These specs ensure heavy-duty fault interruption for high-current circuits while remaining suitable for general-purpose protection in industrial panels. The fuse is non-current-limiting, meaning inrush conditions are not suppressed by the fuse itself.
Yes, for applications requiring protection up to 450 A with a 10 kAIC interrupt rating at 250 VAC. It’s a general-purpose, non-current-limiting fuse suitable for motor feeders and power distribution in industrial panels. If inrush control is needed, consider alternatives designed as current-limiting fuses.
Class H is a standard Bussmann/Eaton fuse family designation that supports straightforward interchange within the Eaton Bussmann ecosystem. The NON-450 is designed for compatible holders and enclosures, enabling quick replacements in existing panel builds without hardware changes. Always match voltage, amperage, and interrupt ratings to avoid undersizing or overprotection.
Being a one-time fuse with a high interrupt rating, the NON-450 reduces downtime during faults and simplifies spare part inventories. Its CE Marked status supports regulatory compliance, contributing to smoother audits and fewer compliance-related delays. ROI comes from improved uptime, predictable protection, and reduced maintenance complexity in mid- to large-scale panels.
