FAQs
The Eaton NON-9 fuse is designed for general-purpose protection in electrical protection and circuit control circuits within industrial automation. With a 9 A rating and a 50 kAIC interrupt capacity, it is ideal for controlling motors, power supplies, and automation logic within standard control panels while maintaining reliable fault isolation and predictable replacement cycles.
As a non-current-limiting fuse, the NON-9 allows inrush currents typical to control circuits to pass without immediate current restriction. This reduces nuisance tripping during startup surges, provided the inrush remains within the panel’s protected design limits. For applications with large startup transients, verify inrush compatibility against the circuit’s total impedance and transformer characteristics.
Yes. The NON-9 is CE marked, indicating compliance with applicable European safety and conformity directives. It is designed for broad industrial use and aligns with Bussmann series data and standard protection practices, supporting regulatory requirements in many regions.
Key specs include a 9 A amperage rating; 50 kAIC interrupt rating at both 125 Vdc and 250 Vac; voltage ratings of 250 Vac and 125 Vdc; and a Class H, non-indicating design. This combination supports reliable circuit protection in standard automation and electrical protection applications.
The fuse measures 2 inches in length with a width and height of 0.56 inches, and weighs about 0.35 lb. It ships in standard packaging with a quantity of 10 units per pack, making it straightforward to stock and replace in control panels.
