6.25 A 250 V AC glass fuse
This Bussmann MDL-series fuse is a cylindrical glass-bodied device rated for 6.25 amperes at 250 volts AC. It provides time-delay, non-rejection over-current protection for equipment that experiences brief inrush currents. The 1-1/4 inch by 1/4 inch form factor fits standard fuse holders used in control panels, instrumentation and similar low-voltage circuits. Buyers who need a faster-acting or high-breaking-capacity fuse for semiconductor protection should look elsewhere.
Sustained overload behaviour
The time-delay element tolerates temporary surges without opening, yet interrupts sustained overloads to protect downstream wiring and components. At 125 V AC the fuse is rated to break 10 kA, while at the nominal 250 V AC its interrupting rating is 200 A. This dual rating means the device remains safe on circuits where the available fault current does not exceed those values. Installations with higher prospective short-circuit current require a fuse with a greater interrupt rating.
Interrupt rating at 250 V AC
The single specification that decides suitability is the 200 A interrupting capacity at 250 V AC. If the circuit can deliver more than 200 amperes under fault conditions, this fuse cannot safely clear the fault and a higher-rated alternative must be selected. For circuits limited to 200 A or less at 250 V AC, the MDL series provides reliable time-delay protection in the standard 1-1/4 inch glass package.

Questions about this item
How much heat does the 6.25 A glass fuse generate during continuous operation?
The fuse carries 6.25 A at 250 V AC with a time-delay design that limits temperature rise under normal load; it opens at 10 kA at 125 V AC or 200 A at 250 V AC to protect the circuit.
What holder or fuse block is required to install the 1-1/4 in x 1/4 in cylindrical fuse?
The MDL-series fuse fits standard 1/4 in diameter by 1-1/4 in length fuse clips, blocks or panel-mount holders rated for 250 V AC and at least 6.25 A.
Can the MDL 6.25 A fuse replace a Littelfuse 313 or Mersen GDL in legacy equipment?
Yes, the supplier lists Littelfuse 313, Littelfuse 315, Mersen GDL and Mersen GDV as equivalent series for direct substitution in existing holders.
