FNM-8/10~FNM-8-10~BUSS MIDGET FUSE
Time-delay design enables controlled response to inrush currents, reducing nuisance trips on small control circuits and improving overall machine uptime. This 0.8 A rating suits sensitive automation components, delivering reliable protection for PLC power feeds and solenoid circuits in modern panels. The fuse offers a robust 10 kAIC interrupt rating at 125 VAC and 35 AIC at 250 VAC, providing strong fault handling for startup surges and short-duration faults in motor starters and I/O racks. Dual-element construction enhances reliability under repeated faults, boosting protective coordination with upstream devices and extending component life in busy automation lines. Ferrule-end x ferrule-end connections with nickel-plated bronze endcaps deliver durable, corrosion-resistant terminations, while the compact 0.39 x 0.39 x 1.44 inch form factor simplifies installation in tight enclosures. CE and RoHS compliance, along with standard packaging, support global procurement and regulatory alignment, reducing spare-parts diversity and simplifying stocking. In practice, installers appreciate quick wiring with standard ferrules and Bussmann-series compatibility, which translates to lower commissioning time and fewer field-service calls.

FAQs
Yes. The FNM-8/10 is rated for 250 V operation and features ferrule-end terminations, enabling reliable, field-friendly wiring in standard control panels. Its 0.8 A time-delay design is well-suited for PLC power feeds, small solenoids, and relay circuits, provided the circuit current remains within the 0.8 A rating and proper ferrules are used.
The device provides 10 kAIC interrupt rating at 125 VAC and 35 AIC at 250 VAC. This means it can safely interrupt high fault currents at lower voltages and offer strong protection against short-duration faults in higher voltage configurations, helping to prevent cascading failures in automation panels.
Applications include PLC power feeds, small solenoid and actuator circuits, and control-relay panels where inrush currents occur during startup. The time-delay characteristic tolerates brief surges without nuisance tripping, improving line uptime in automated assembly, packaging lines, and robotic control systems.
Yes. The fuse is CE marked and RoHS compliant, ensuring regulatory alignment for European markets and environmentally responsible manufacturing practices. This supports compliant product integration across global automation projects.
The FNM-8/10’s standard ferrule-end design and Bussmann-series compatibility reduce stocking variety, lowering spare-parts complexity. Its reliability in time-delay protection minimizes nuisance trips and maintenance downtime, translating to lower lifecycle costs and faster mean time to repair (MTTR) in automated production lines.
