FNM-5-6/10~FNM-5-6-10~BUSS MIDGET FUSE
Feature → Business Impact → Application: Time-delay, dual-element design helps suppress nuisance trips during inrush and startup surges, reducing unplanned downtime and extending equipment life in motor drives and switching power supplies. Application: ideal for control panels and small drives where inrush is common. Feature → Business Impact → Application: Compact footprint (0.39 in L x 0.39 in W x 1.44 in H) enables fitment in crowded enclosures and panel boards, simplifying retrofit projects and OEM designs. Application: space-constrained electrical cabinets and control boards. Feature → Business Impact → Application: High interrupt ratings (10 kAIC at 125 Vac; 200 AIC at 250 Vac) deliver robust fault current protection, improving safety margins and reducing downstream damage. Application: AC distribution, compact power rails, and protective device coordination. Feature → Business Impact → Application: Ferrule-end x ferrule-end connections with nickel-plated bronze endcaps provide durable, low-resistance terminations, lowering wiring costs and maintenance needs. Application: field-installable fuses in industrial panels with high vibration or thermal cycling. Feature → Business Impact → Application: Non-indicating fuse with standard packaging ensures quick identification during maintenance, while “Superior overload and cycling capabilities” reduce replacement frequency. Application: panel boards in manufacturing lines and packaging systems.

FAQs
The FNM-5-6/10 uses ferrule-end x ferrule-end terminations and nickel-plated bronze endcaps, providing a robust, solder-free connection suitable for standard Bussmann series panel boards. It fits in compact enclosures where ferrule terminations are preferred and enables reliable, repeatable servicing in control cabinets and electrical distributions.
This fuse is rated for 5.60 A with a 250 V voltage rating. It provides an 10 kAIC interrupt rating at 125 Vac and 200 AIC at 250 Vac, making it suitable for protecting circuits with moderate inrush and higher fault currents while maintaining quick-clearing performance.
Yes. Its time-delay (dual-element) design is specifically intended to tolerate temporary inrush currents typical of motors and equipment startups, reducing nuisance tripping while still delivering reliable overload protection to prevent motor damage and downtime.
The FNM-5-6/10 is CE marked and RoHS compliant, ensuring adherence to essential EU safety, health, and environmental standards. These certifications help manufacturers meet regulatory obligations, simplify market access, and reassure end users about product safety and sustainability.
With a non-indicating design, periodic inspection is recommended to verify seating and endcap integrity, especially in harsh environments. Plan for standard replacement cycles aligned with maintenance schedules. The fuse’s durability and cycling capability help reduce replacement frequency, contributing to improved line uptime and lower lifecycle costs.
