Five cylindrical glass fuses with metal end caps

Bussmann

Bussmann MDL-3-R 3A 250V Time-Delay Glass Fuse 5PK

SKU CH-GPEC-N7BYB

Pack of five 3 A 250 V AC time-delay glass fuses with a 100 A interrupt rating at 250 V

  • 3 A rating protects low-current circuits reliably
  • Time-delay design tolerates brief inrush surges
  • 250 V AC rating suits mains-voltage equipment
  • 100 A interrupt rating at 250 V AC breaks faults safely
  • Pack of five gives ready spares for maintenance

3 A 250 V glass fuse for circuit protection

This pack contains five cylindrical glass fuses rated at 3 amperes and 250 volts AC. They belong to the MDL series and feature a time-delay characteristic that tolerates brief inrush currents without opening. The 1-1/4 inch by 1/4 inch form factor fits standard fuse holders used in many electrical and electronic devices.

Time-delay action handles sustained overloads

The time-delay element allows the fuse to withstand temporary current surges such as motor start-up or transformer energising. Interrupt ratings are 100 A at 250 V AC and 10 kA at 125 V AC, so the fuse can safely clear significant fault currents. Glass construction lets you visually confirm the element status after an event.

Direct replacement for MDL MDQ MDV MDX

These fuses cross-reference to Bussmann MDL, MDQ, MDV, MDX and Littelfuse 313, 315 as well as Mersen GDL, GDV series. They suit equipment that specifies any of those series in the same 3 A 250 V rating. Buyers who need a different current rating or a fast-acting fuse should select another part.

Highlights

  • 3 A rating protects low-current circuits reliably
  • Time-delay design tolerates brief inrush surges
  • 250 V AC rating suits mains-voltage equipment
  • 100 A interrupt rating at 250 V AC breaks faults safely
  • Pack of five gives ready spares for maintenance

Questions about this item

How much heat does the MDL-3-R generate when carrying 3 A continuously?

The fuse runs at its rated 3 A without excess heat; the glass body and time-delay element are designed for normal operation at 250 V AC.

What holder or block must I already have to install these 1-1/4 in x 1/4 in cylindrical glass fuses?

You need a standard 1/4 in diameter by 1-1/4 in length fuse clip, panel mount holder or inline holder that accepts non-rejection cylindrical glass fuses.

Can the MDL-3-R replace an older Littelfuse 313 or Mersen GDL in the same circuit?

Yes, the MDL-3-R is listed as equivalent to Littelfuse 313, 315 and Mersen GDL, GDV series, matching the same 3 A, 250 V AC time-delay ratings.
