Description

Time-Delay Fuse 3A, 250 Vac, 1.25 Inch x 0.25 Inch, Ferrule End Connection

Features

  • Standardized to the common 6.3mm x 32mm physical footprint, this glass tube fuse is a direct-replacement solution for a massive range of electronic ballasts, control circuits, and small appliances. The nickel-plated brass endcaps ensure high conductivity and corrosion resistance, preventing voltage drops and ensuring a secure mechanical fit in both clip-style and screw-cap holders.
  • Designed with the MDL "slow-blow" characteristic, this fuse is specifically engineered to withstand the brief, high-energy inrush currents typical of inductive loads like small motors and solenoids. While a standard fuse would nuisance-trip during startup, this time-delay element allows the equipment to cycle on normally while still providing critical protection against genuine, sustained overcurrent events.
  • Precision-calibrated to blow at 3 Amps, this fuse acts as the "weak link" in your electrical system to sacrifice itself before expensive internal components are damaged. The 250V rating makes it versatile for both standard 120V household electronics and higher-voltage industrial control loops, providing a wide safety margin for various power distribution environments.
  • This "R" suffix model is fully RoHS compliant, meaning it is manufactured without lead or other hazardous substances, making it the ideal choice for modern, eco-conscious manufacturing and repair. Being UL Listed and CSA Certified, it guarantees that the fuse will clear a fault safely without shattering the glass tube, protecting both the user and the surrounding equipment from fire hazards.
