Fuse for 4 A 250 V AC circuits
This pack contains five cylindrical glass fuses rated at 4 A and 250 V AC. They are designed for equipment that requires a time-delay response to tolerate brief inrush currents. The MDL series suits maintenance on instruments, control panels and similar low-voltage apparatus. Buyers needing a different current or voltage rating should select another part.
Verify rating and holder compatibility
Confirm the circuit calls for a 4 A time-delay fuse at 250 V AC before fitting. The fuse body measures 1-1/4 in length by 1/4 in diameter, so the holder must accept that form factor. Interrupt ratings are 10 kA at 125 V AC and 200 A at 250 V AC; ensure the prospective fault current does not exceed these values. The non-rejection design fits standard clips without a keyed slot.
Five-piece pack simplifies spares holding
Supplied as a five-pack, the bundle lets technicians keep replacements on hand for multiple sites or repeated service calls. Equivalent series references include 313, 315, GDL, GDV, MDL, MDQ, MDV and MDX for cross-referencing existing bills of materials. No additional hardware or software is included with the fuses.

Questions about this item
What comes in the 5-pack and is any extra hardware required?
The pack contains five 4 A 250 V AC time-delay glass fuses; no additional hardware is included or required for installation.
How do I decide between the listed equivalent series such as MDL, MDQ, MDV, MDX, 313, 315, GDL and GDV?
All listed series share the same 4 A, 250 V AC, time-delay, cylindrical glass construction and 1-1/4 in by 1/4 in dimensions, so any will fit the same holder.
What does the 10 kA interrupt rating at 125 V AC mean for everyday use?
It indicates the fuse can safely break a fault current of up to 10 000 amperes at 125 V AC without rupturing, protecting downstream wiring and equipment.
