Mersen AF-5 – Frequently Asked Questions

1) Will the Mersen AF-5 automotive fuse work in a 12V car or truck fuse block?
Yes. The AF-5 is rated 32 VAC / 32 VDC, which covers standard 12V and 24V vehicle electrical systems. It uses blade terminals and clips into standard automotive fuse blocks, so it drops into cars, trucks, and other low voltage circuits.
2) What amp ratings does the Mersen AF-5 fuse cover?
The AF-5 automotive fuse family spans 1 to 40 amps, so one part family covers most low voltage vehicle circuits from small accessory and instrument loads up through heavier feeds like blowers and power accessories. Specify the amp value you need to match the circuit the fuse protects.
3) Is a fast-acting fuse the right choice for automotive wiring, or do I need a time-delay fuse?
The AF-5 is fast-acting, meaning the element opens quickly on overcurrent. That is what you want for protecting wiring and solid state electronics in vehicle circuits, where a short should clear fast. Circuits with a high inrush at startup, like some motor loads, are usually better served by a time-delay fuse that rides through the surge.
4) What is the interrupt rating on the Mersen AF-5 automotive fuse?
1 kA AC. That is the maximum fault current the AF-5 can safely interrupt, which is ample for the available fault current in typical 12V and 24V vehicle battery circuits.
5) Is the Mersen AF-5 fuse UL listed and RoHS compliant?
The AF-5 carries UL certification under file references AU2915 FHXT.AU2915E244928 and JDYX2.E244928, and it is listed as RoHS compliant. That matters for fleet and institutional maintenance departments that have to document the parts going into their vehicles.
6) Why does the Mersen AF-5 use silver-plated contacts?
The blade terminals on the AF-5 are silver-plated, which keeps contact resistance low where the fuse clips into the holder. In a vehicle that sees vibration, heat cycling, and moisture, that plating is what holds a clean connection over repeated removal and reinstallation. The body itself is plastic.
7) Can I buy Mersen AF-5 automotive fuses in bulk for a fleet shop?
Yes. The AF-5 is sold in a 100-pack, which is how shops and fleet maintenance operations stock replacement fuses rather than buying them a few at a time.
