FAQs
The FNM-3/4 uses ferrule-end terminations and is designed for standard 250 V circuits in small control panels and automation equipment. Its compact 0.39 x 0.39 in footprint and 1.44 in height fit crowded enclosures, while the nickel-plated endcaps provide durable, corrosion-resistant connections for ongoing field service and panel upgrades.
Key specs include a 0.75 A current rating, 250 V voltage rating, non-indicating operation, dual-element configuration, and interrupt ratings of 10 kAIC at 125 VAC and 35 AIC at 250 VAC. These figures translate to reliable overload protection with effective fault-current handling in small automation circuits.
Yes. The time-delay, dual-element design tolerates short surges typical of motor and solenoid start-ups, preventing nuisance trips while still delivering robust protection against prolonged overloads. This makes it suitable for small motors and control circuits in panel assemblies.
The device is CE Marked and RoHS Compliant, ensuring regulatory alignment for EU markets and global supply chains. These certifications help reduce compliance risk for OEMs deploying the fuse across international sites and in RoHS-restricted environments.
The FNM-3/4’s precise time-delay protection minimizes downtime from nuisance trips, while its durable ferrule terminations and endcaps reduce replacement frequency. Its small footprint frees panel space, and standard packaging simplifies stocking and maintenance planning, delivering lower total cost of ownership in automated systems.
