Bussmann series Class H (K) Fuses Data Sheet no. 1030
Feature → Business Impact → Application: The NON-90 delivers a 90 A amperage rating with a high interrupt rating of 10 kAIC at 250 Vac and 50 kAIC at 125 Vdc, enabling fast fault interruption and reduced downtime in control panels and power distribution. This translates to improved equipment reliability and lower maintenance costs, especially in high-load industrial environments where permission to tolerate brief overcurrents is limited. Application-wise, it fits general-purpose circuits in machinery, enclosures, and panelboards that require dependable protection without current limiting, allowing smooth operation under nominal loads while preserving downstream components. Feature → Compatibility → Installation: Blade end x blade end connections align with standard Class H fuse holders and Bussmann cataloging, enabling rapid stocking and straightforward retrofits. This minimizes installation time and inventory complexity in maintenance shops and manufacturing lines, while the 5-per-pack packaging aids warehousing efficiency. Feature → Compliance → Risk management: CE marking ensures compliance with EU safety standards, reducing regulatory risk during audits and simplifying cross-border deployments. Pin-indicating capability (where available) supports quick status checks during inspections and servicing, reducing the risk of undetected fuse faults and unplanned downtime.

FAQs
The NON-90 uses blade end x blade end connections designed for standard Bussmann Class H fuse holders. It fits common panelboard and control enclosure DIN rail or block styles that accept Class H fuses. Verify enclosure space and clearance for the 1.6 in depth by 5.88 in height footprint and ensure the holder supports non-current-limiting, non-indicating fuses.
The NON-90 is rated for 90 A and accommodates voltage ratings of 250 Vac and 125 Vdc. It provides an interrupt rating of 10 kAIC at 250 Vac and 50 kAIC at 125 Vdc, making it suitable for protecting general-purpose circuits in mixed AC/DC environments while maintaining fast fault clearance.
Yes, the NON-90 is a general-purpose, non-current-limiting Class H fuse intended for protection of standard control circuits and general panel protection. It is not designed for motor protection where current-limiting or time-delay characteristics are required; for those applications, a motor-rated fuse or contactor coordination may be more appropriate.
The NON-90 carries CE marking indicating compliance with applicable European safety standards. While CE is the primary certification listed, Eaton also provides tooling and resources for RoHS compliance verification for this product family, supporting regulatory alignment across markets.
Using the NON-90 can reduce downtime due to its reliable fault interruption and straightforward replacement in standard Class H fuse blocks. The 5-count packaging simplifies inventory management, and the compact form factor supports easier service access in tight panels. Overall, you gain predictable maintenance intervals, straightforward sourcing from Eaton’s Bussmann line, and lower total cost of ownership.
