Eaton NON-2-1/2 Fuse - Class H Non-Current-Limiting
Part Number: NON-2-1/2
Quick Summary
Eaton NON-2-1/2 fuse provides general-purpose overcurrent protection for small control and power circuits in industrial panels. When a fuse is undersized or oversized, it can cause nuisance trips or insufficient protection, driving downtime. CE Marked compliance and Class H construction reinforce reliability, while the 50 kAIC interrupt rating at 125 Vdc and 250 Vac ensures robust fault handling. The device’s ferrule-end connections simplify installation, and its non-current-limiting design balances cost with predictable operation. By matching the 2.5 A rating to typical control circuits and referencing Bussmann’s full-line catalog, buyers gain predictable performance, easy replacements, and straightforward procurement for panel builders and OEMs.
