MDL Slow Blow Fuses: Time-Delay Protection for DC and AC Systems

MDL slow blow fuses provide reliable time-delay protection for DC systems rated up to 32V and AC systems rated up to 250V. Constructed with glass tubing and nickel-plated brass endcaps, these fuses offer a visible indication when blown, making it easy to detect issues in your application. MDL fuses are ideal for applications where inrush currents may occur, allowing them to handle temporary overloads without immediately blowing.

Available in a range of 3 to 30 amps, these fuses are UL, CSA, CE, and RoHS compliant, ensuring they meet global safety standards. Compatible with MDL fuse holders (79910, 79911, 79031, and 79032), these slow blow fuses provide durable, long-lasting protection for both DC and AC systems.


  • Available in 3-30 Amps.
  • Maximum Voltage: 32V DC, 250V AC.
  • UL, CSA, CE & RoHS Compliant.
  • Can be used with MDL fuse holders 79910 & 79911, 79031, and 79032.
