Eaton NON-250 Fuse - CE Marked, 250 A, 10 kAIC
Part Number: NON-250
Quick Summary
Eaton NON-250 fuse is a general-purpose, non-current-limiting protection device designed for industrial power systems and motor control panels. It helps engineers prevent nuisance outages by providing predictable, one-time fuse protection that fails open when faulted. CE Marked compliance ensures global compatibility and safer installation in diverse environments. This Class H fuse handles up to 250 A with a 10 kAIC interrupt rating at 250 VAC, delivering reliable protection without current limiting that can affect startup sequences. For procurement teams, the fuse’s blade-end connections and standard packaging simplify stocking and fast replacement, while its compact form supports streamlined panel design and easier field upgrades.

Bussmann series Class H (K) Fuses Data Sheet no. 1030
Feature: Non-current-limiting Class H design. Impact: Delivers predictable protection without altering startup currents or system filters, reducing unwanted interactions in control circuits. Application: Suitable for general protection in motor controls and power distribution where reliable fuse operation is critical. Feature: 250 A amperage rating with a 10 kAIC interrupt rating at 250 VAC. Impact: Provides strong fault clearing for high-load circuits, minimizing damage to wiring and components. Application: Used in service entrance panels, distribution blocks, and control circuits requiring robust overcurrent protection. Feature: Blade end x blade end connections and standard packaging. Impact: Enables fast, drop-in replacement with minimal rewiring or adapters, improving field service uptime. Application: Retrofit into existing Eaton Bussmann or other blade-end fusible disconnects and panel boards. Feature: One-time fuse with non-indicating indicator. Impact: Reduces maintenance management by using a single-use device that clearly signals a blown fuse. Application: Preferred in critical systems where single-use protection simplifies diagnostics and spare-part planning. Feature: CE Marked compliance and Class H labeling. Impact: Supports regulatory compliance across international installations, easing procurement for multilingual teams. Application: Global manufacturing plants and service centers needing CE-compliant overcurrent protection. Feature: Compact dimensions: 8.63 in length, 2.06 in width and height. Impact: Fits compact enclosures without crowding other components, enabling tighter panel layouts. Application: Electrical protection where space is at a premium, including control panels and switchgear assemblies.

FAQs
Yes. The NON-250 uses blade end x blade end connections and standard packaging, enabling drop-in replacement in most blade-type fuse holders found in control panels, MCCs, and distribution boards. Ensure the holder is rated for 250 A and 250 V and that the system is de-energized before replacement. Verify clearance and mounting fit during installation.
Key specs include a 250 A amperage rating, 250 V voltage rating, and a 10 kAIC interrupt rating at 250 VAC. It is a Class H, non-current-limiting, one-time fuse with blade-end connections and a non-indicating fuse indicator. These parameters define its suitability for high-load protection in industrial power distribution.
The NON-250 is designed for general overcurrent protection in motor control centers, power distribution panels, and industrial machinery. Its non-current-limiting behavior makes it ideal where startup currents and protection coordination must remain unaffected, while the 10 kAIC rating provides robust fault clearing for demanding process environments.
Yes, the NON-250 is CE Marked, indicating compliance with European safety standards. This simplifies regional procurement and supports regulatory compliance for global installations. Always verify local electrical codes and any additional country-specific certifications required for your application.
The NON-250 is a single-use, non-indicating fuse that minimizes downtime by providing clear, predictable fault protection and straightforward replacement. Its standard dimensions and blade-end connections reduce spare-parts inventory and field labor time, delivering improved uptime and lower maintenance costs over the fuse lifecycle.
