Eaton NON-6-1/4 Fuse - CE Marked Class H, 50 kAIC
Part Number: NON-6-1/4
Quick Summary
Eaton Bussmann NON fuse provides non-current-limiting protection for general‑purpose circuits in industrial equipment. Users often confront nuisance trips or mismatched protection that cause unplanned downtime during startups and load changes. This device carries CE Marking and Bussmann Class H classification, with an interrupt rating of 50 kAIC at 125 Vdc and 250 Vac, ensuring fast, dependable fault interruption. Designed for motor controllers, control panels, and power distribution blocks, it delivers reliable protection while enabling straightforward stocking and routine maintenance. The 6.25A rating suits small to medium loads, and the compact 0.56 in depth with a 2 in height helps engineers fit into tight enclosures. With non‑current‑limiting behavior and a 10‑pack per order, procurement teams can optimize spares and reduce downtime.

FAQs
The NON-6-1/4 fuse is designed for Bussmann Series Class H protection applications and fits standard Bussmann Class H holders used in control panels and power distribution blocks. When replacing an existing fuse, verify the holder’s ratings match 6.25A and the dual-voltage capability (250 VAC / 125 VDC) to ensure safe operation and reliable interruption during faults.
Key ratings include a 6.25A amperage rating, an interrupt rating of 50 kAIC at 125 VDC and 250 VAC, and voltage ratings of 250 VAC and 125 VDC. The fuse is classified as Class H and is CE marked, with a non-current-limiting behavior suitable for general-purpose protection in many industrial circuits.
Recommended for general-purpose protection in motor controllers, control panels, and power distribution blocks within industrial equipment. Its non-current-limiting design helps avoid nuisance trips during normal startup surges, while its high interrupt rating provides robust protection for higher fault currents common in industrial settings.
The fuse carries CE Marking and belongs to Bussmann Class H family, aligning with European and international safety standards. This certification simplifies compliance for multi-site deployments and supports regulatory approvals for machines assembled in or shipped to CE-mark regions, improving vendor reliability and customer confidence.
Maintenance benefits come from predictable performance and easy spares management, with a packaging quantity of ten per order simplifying inventory. The non-current-limiting design reduces nuisance trips, potentially lowering downtime during routine operation and startup, while the robust 50 kAIC rating provides strong fault protection that can minimize costly equipment damage.
