Littelfuse AGA5 AGA Series 5A Glass Fuse

The Littelfuse AGA5 is a 5A-rated glass fuse from the AGA Series, part of Littelfuse's AG Glass Fuse family of circuit protection components. Engineered for dependable overcurrent protection, this glass tube fuse is built as an aftermarket replacement for automotive and general low-voltage electrical circuits that require a precise 5 ampere rating. Its clear glass-body construction allows technicians to quickly visually confirm fuse condition without pulling it apart, which speeds up troubleshooting whether the fuse is being serviced in the field or on the bench. The AGA5 is documented in Littelfuse's Aftermarket Glass Fuse Data Sheet, supporting accurate cross-reference for replacement and stocking purposes.

Key Features

  • Ampere Rating: 5A for precise, consistent overcurrent protection on circuits sized for this load.

Littelfuse AGA-5 – Frequently Asked Questions

1) What amperage is the Littelfuse AGA5 glass fuse rated for?
The AGA5 is a 5 amp glass tube fuse. It protects circuits sized for a 5A load, so use it only where the original fuse was also 5A. Going up in amperage to stop nuisance blowing lets the wiring carry more current than it was sized for.
2) Is the AGA5 a direct replacement for the fuse already in my automotive fuse block?
It is if what you are replacing is an AGA-style 5A glass fuse. The AGA5 uses the standardized AGA glass tube body, which is what makes it cross-reference and drop into common automotive and equipment fuse holders and blocks. Match the existing fuse's series designation and amp rating before swapping, since AG family fuses come in several body sizes that are not interchangeable.
3) Can a Mersen A2D-R Class RK1 time-delay fuse be used in place of the Littelfuse AGA5 glass fuse?
No. The Littelfuse AGA5 is a 5A glass-body tube fuse from the AGA Series, sized for aftermarket automotive and general low-voltage circuits and dropped into standard glass fuse holders and fuse blocks. The Mersen A2D-R is a Class RK1 time-delay fuse, a branch-circuit power distribution fuse that mounts in RK1 fuse clips or blocks, not a glass tube holder. The two are different fuse classes with different bodies and mountings, so one cannot replace the other in the same holder.
4) For a 250V branch circuit needing time-delay protection rather than an automotive glass fuse, what is the alternative to the AGA5?
Look at the Mersen A2D-R Class RK1 time-delay fuse, rated 250VAC/250VDC and fitted with SmartSpot indication that shows an opened fuse at a glance. The Littelfuse AGA5 is a 5A glass tube fuse intended for aftermarket automotive and general low-voltage service work, where its clear glass body serves the same quick-check purpose. Choose the A2D-R when the equipment calls for an RK1 class fuse in distribution gear, and the AGA5 when the holder is a glass tube fuse block.
5) What should I use instead of the AGA5 on a medium voltage circuit?
The AGA5 is not suitable there. It is a 5A AGA Series glass tube fuse for low-voltage automotive and equipment circuits. For medium voltage transformer and motor circuit protection, the Mersen D0R0 Series Amp-Trap E-rated medium voltage fuse with ferrule terminals is the correct family. E-rated medium voltage fuses mount in dedicated clips rather than a glass fuse holder, so confirm the holder and terminal style before ordering.
6) What part number do I order for the Littelfuse AGA 5 amp glass fuse?
Order Littelfuse MPN AGA-5. That is the 5 amp member of the AGA Series within Littelfuse's AG Glass Fuse family, and it is the number to quote when cross-referencing or setting up a stocking line.
7) Why use a glass fuse instead of a blade fuse for service work?
The glass body is the reason. The AGA5 has a transparent housing, so a technician can see a blown element without pulling the fuse out of its holder, which shortens troubleshooting on the vehicle or on the bench. Blade fuses are the newer automotive standard; glass tube fuses like this one are what older vehicles, instrument panels, accessory wiring and equipment fuse blocks were built around.
8) Is the Littelfuse AGA5 built to OEM specification for automotive replacement?
It is manufactured to match OEM specifications as an aftermarket replacement for automotive and general low-voltage circuits needing a 5 amp rating, and it is documented in Littelfuse's Aftermarket Glass Fuse Data Sheet, which is what makes cross-referencing to an OEM fuse number straightforward for stocking.
9) Is the Square D PowerLogic meter fuse pack a substitute for the Littelfuse AGA5?
No. The Square D EMFP3 is a set of three 0.5A 600V fuses supplied specifically for PowerLogic energy meter voltage inputs. The Littelfuse AGA5 is a single 5A AGA Series glass fuse for automotive and general low-voltage circuits. The amperage ratings and the intended circuits are different, so the meter fuse pack is not an interchange for a 5A glass fuse and the AGA5 should not be dropped into a metering circuit specified for 0.5A.
10) For a high-amperage feeder, is there anything comparable to the AGA5 in the same brand family?
The AGA5 tops out as a 5A glass tube fuse, so it does not cover feeder-level loads. For a 400A feeder the Mersen A2D400R is a Class RK1 400A time-delay fuse with SmartSpot indication. Keep the AGA5 for the small accessory, instrument panel, and control circuits that are sized around 5A and use a glass fuse holder.
11) What is the AGA5 actually used for on a job?
Typical work is aftermarket automotive electrical circuits, instrument panel and accessory wiring, replacement in glass tube fuse holders and fuse blocks, and general low-voltage equipment and panel circuit protection during service and repair. It is a maintenance and repair item, not a design-in component for new distribution equipment.
