Feature → Business Impact → Application: General-purpose Class H NON fuse provides dependable protection for control circuits, reducing nuisance trips and maintenance costs in machine bays and panels. This translates to improved uptime and predictable service intervals in automation systems. Application: Control panels, PLC rack feeds, and small motor circuits requiring reliable 45 A protection with straightforward, ferrule-end wiring. Feature → Business Impact → Application: Non-current-limiting design preserves circuit behavior for certain inductive loads, enabling safer inrush handling and easier coordination with upstream protection. Application: Conveyor drives, feed lines in packaging lines, and machine tool controllers where precise coordination matters. Feature → Business Impact → Application: 50 kAIC interrupt rating at 125 Vdc and 250 Vac provides strong fault clearance, minimizing arc energy and equipment damage during faults. Application: Main feeders, MCC sections, and protective interlocks inside power distribution enclosures. Feature → Business Impact → Application: Ferrule end x ferrule end connections enable fast, secure terminations with compatible bus bar or terminal block hardware. Application: Quick swaps on serviceable panels and retrofit projects requiring minimal rewiring. Feature → Business Impact → Application: Standard packaging of 10 pieces supports efficient stocking and reordering for maintenance teams. Application: Stocking in repair spares kits for production lines and industrial facilities.

FAQs
Install the NON-45 with ferrule-end connections into compatible terminal blocks or fuse holders designed for Class H Bussmann fuses. Ensure the circuit voltage does not exceed 250 Vac, and verify a 45 A rating matches the protected load. Use proper de-energization and follow lockout/tagout procedures during replacement to prevent arc and shock hazards.
The NON-45 fuse provides a 50 kAIC interrupt rating at 125 Vdc and 250 Vac. This makes it suitable for general-purpose protection in control panels, small motor feeders, and automation circuits where high energy faults could occur and rapid, safe interruption is required.
Yes, as long as the operating voltage remains within the rated 125 Vdc maximum. The 24 Vdc circuits fall well within the 125 Vdc rating, making the NON-45 appropriate for many low-voltage control applications while maintaining the 45 A protection and 50 kAIC interrupt capability.
The NON-45 fuse is CE Marked, indicating compliance with applicable European electrical safety and performance standards. For verification, reference Eaton’s documentation and the CE marking on the product packaging; use Eaton’s RoHS and compliance tools if needed to confirm current status across your locale.
With a 10-piece packaging and standard Bussmann form factor, stocking and reordering are straightforward for maintenance teams. Its non-indicating status reduces cost and complexity, while the 50 kAIC rating and 45 A capacity deliver reliable protection with minimized downtime, improving overall ROI in automated facilities.
