FAQs
The NON-400 uses blade end x blade end connections and ships as a standard, single-unit fuse. For installation, power down equipment, verify rating compatibility (400 A, 250 V), insert the blade terminals into the corresponding fuse holder sockets, and ensure proper seating. Confirm the panel's space and cabling accommodate the 8.63 in length and 2.06 in width. After installation, perform a system check to confirm correct alignment and secure seating to prevent vibration-induced contact issues.
The NON-400 features a 400 A amperage rating with a 10 kAIC interrupt rating at 250 VAC, providing reliable fault clearance for heavy feeders. As a non-current-limiting fuse, it offers robust protection without introducing current-limiting behavior that might affect coordination. This makes it well-suited for motor control centers and power distribution panels where predictable protection and straightforward replacement are essential.
Yes. The NON-400 is CE marked, indicating compliance with European safety requirements, and Eaton provides RoHS information via its compliance tools. This helps ensure regulatory alignment for installations across international sites and simplifies documentation for audits and certifications.
Recommended for electrical protection in power distribution panels, motor control centers, and legacy switchgear in manufacturing, process industries, and industrial automation. Its Class H construction, robust interrupt rating, and blade-end connectivity make it a practical choice for both retrofit projects and new installations that require consistent Bussmann protection across facilities.
With a standard packaging approach and a straightforward blade-end design, the NON-400 reduces replacement time and downtime during maintenance. Its 400 A rating and 10 kAIC rating help prevent costly damage from faults while enabling easy sourcing of spare fuses from the Bussmann series. Overall, operators benefit from improved uptime, reduced maintenance complexity, and predictable total cost of ownership.
