Eaton NON-75 Fuse - Class H, 75 A, 10 kAIC at 250 Vac
Part Number: NON-75
Quick Summary
Eaton Bussmann NON-75 fuse provides general-purpose circuit protection for industrial control panels. This fuse guards electrical circuits against overcurrent events by interrupting faults, reducing downtime and protecting costly equipment. In practice, engineers rely on a non-current-limiting design when coordination with upstream protection and selectivity is essential, making this device ideal for legacy systems and older panel architectures. With CE marking and RoHS information available via Eaton's RoHS search tool, regulatory alignment across regions becomes easier to confirm. The NON-75 also benefits from standard Bussmann Class H form-factor compatibility and a compact 5.88 in length, supporting easier installation in crowded enclosures. For buyers seeking reliable, widely supported protection, this fuse offers solid performance with straightforward replacement.

FAQs
The NON-75 fits standard Bussmann Class H fuse holders and is sized for a 5.88 in length with 1.06 in width and height, enabling straightforward installation in common control panels and distribution enclosures.
The fuse is rated for 75 A, with voltage ratings of 250 Vac and 125 Vdc. Its interrupt ratings are 10 kAIC at 250 Vac and 50 kAIC at 125 Vdc, classifying it as a robust general-purpose, non-current-limiting device.
The NON-75 is a non-current-limiting fuse intended for general protection; it supports 125 Vdc but is not optimized for high inrush suppression. For circuits with frequent high inrush, consider a current-limiting alternative or detailed coordination with upstream protection.
The fuse is CE Marked, signaling EU compliance, and Eaton provides RoHS compliance information via its RoHS search tool to support regulatory reviews for multi-region deployments.
As a one-time fuse, it should be replaced after a fault occurrence. The product ships in standard packaging (5 pieces), facilitating stocking for maintenance teams and minimizing downtime during replacement.
