Eaton FNM-35 Fuse - Time-delay Dual Ferrule, 250V
Part Number: FNM-35
Quick Summary
Eaton FNM-35 fuse is a time-delay dual-element protector for electrical panels. Engineers often contend with nuisance trips during startup or cycling loads, which disrupt uptime and increase maintenance costs. The data for this model shows Not Applicable for warranty and compliances, while its nickel-plated bronze endcaps and ferrule-end connections support robust, long-life performance. For panel protection and motor-control applications, the FNM-35 delivers reliable overload protection at 35 A and 250 V, helping you reduce downtime and protect valuable equipment.

Feature: Time-delay design provides short-term overload tolerance, enabling safe startup of motors and heat-load equipment. Business impact: reduces nuisance trips and extends component life, lowering maintenance costs. Application: ideal for motor starters, pumps, and HVAC controls where startup surges occur. Feature: Dual-element construction increases reliability under repetitive cycling. Business impact: longer service life and fewer replacement outages, improving asset uptime. Application: heavy cycling environments such as conveyors and process lines. Feature: Ferrule end x ferrule end connections shorten installation time and improve contact reliability. Business impact: faster panel wiring and lower commissioning risk. Application: retrofit projects and new panel builds with standard ferrule-term hookups. Feature: Nickel-plated bronze endcaps resist corrosion in harsh environments. Business impact: durable, consistent performance and reduced maintenance inventory. Application: industrial environments with exposure to moisture or contaminants. Feature: 250 V rating with standard packaging and a non-indicating fuse element. Business impact: straightforward integration in common control circuits and simplified procurement. Application: general protection across 250 V distribution schemes. Feature: Superior overload and cycling capabilities support longer lifecycles in demanding applications. Business impact: reduces total cost of ownership through fewer fuse replacements. Application: power distribution and protection across protection panels and control cabinets.

FAQs
Install the FNM-35 by inserting it into ferrule-ended terminals compatible with standard Bussmann-series fixtures. Ensure proper seating, apply the recommended torque to terminal connections, and verify the unit is oriented for airflow. The dual-element design helps manage startup surges without nuisance trips.
Time-delay, or slow-blow, fuses like the FNM-35 tolerate short overloads typical of motor startup and heater inrush. Use it where cycling loads are frequent and brief overloads are expected, to protect conductors while preventing unnecessary outages.
Yes, for 250 V circuits up to 35 A. Its time-delay and dual-element design are well-suited for motor starters and processes with regular surges. For critical motors, pair with proper control schemes and verify coordination with upstream protections.
The provided data lists Compliances as Not Applicable. Verify with Eaton’s datasheets or your compliance team for any site-specific standards or regional requirements applicable to your installation.
The dual-element construction and corrosion-resistant nickel-plated endcaps extend service life, reducing replacement intervals and maintenance costs. Coupled with easy ferrule-term wiring, you can achieve faster commissioning and lower total cost of ownership in densely populated control cabinets.
