Eaton Bussmann series FNM fuse, Time-delay Midget fuse, 3 A, Dual, Non-indicating, Ferrule end x ferrule end, 10 kAIC at 125 Vac,100 AIC at 250 Vac, Nickel-plated bronze endcap, Standard, 250 V

Features

  • The Eaton Bussmann FNM-3 features a dual-element, slow-blow design engineered specifically to withstand momentary high inrush currents and temporary inductive surges. This time-delay functionality protects your critical transformers and small motor circuits without causing the frustrating nuisance blows common with standard, fast-acting fuses.
  • This 3 Amp cartridge fuse is built to the industry-standard 5AG midget specification, measuring precisely 0.41 inches in diameter by 1.5 inches in length. This universal physical footprint ensures a perfect, secure fit into your existing panelboards, control circuit fuse blocks, or inline ferrule-end holders.
  • The FNM-3 carries a robust 250 VAC voltage rating, featuring an interrupting rating of 100A at 250 Vac and up to 10 kAIC at 125 Vac. This targeted supplemental protection effectively isolates localized faults within electrical equipment, safeguarding your upstream electrical infrastructure from catastrophic damage.
  • ? Designed with a durable melamine tube and nickel-plated bronze endcaps, this supplemental fuse offers superior thermal stability and structural integrity. It resists internal pressure and harsh environmental cycling, ensuring long-term reliability where cheaper glass alternatives often fail under stress.
