20A Low Profile Mini Fuse Kit Manual Reset Blade Fuses - Reliable

Our review of the 20A Low Profile Mini Fuse Kit finds it useful for owners who need a simple, reusable solution for blown fuses during on-the-road troubleshooting. This kit is aimed at automotive and marine DIYers who want a 20 amp manual reset blade fuse that works across DC systems from 12V to 32V and can be toggled instead of replaced, making it the single biggest reason to buy: the ability to reset and continue diagnosing without fishing for spare fuses. It is especially handy in emergency repairs for cars, boats, RVs and trucks where speed and reusability matter.

Key Features

• Manual reset: Lets you reset the circuit after a trip instead of swapping fuses, which speeds troubleshooting when chasing wiring shorts.
• Low profile T3 blade: The 2.9 mm wide blades fit standard ATM slots and are compact for many fuse panels while remaining robust for 20 amp circuits.
• Wide DC range: Rated for use in 12V to 32V systems with a maximum of 28 VDC, so it suits cars, RVs and marine 12V systems.
• 12-pack convenience: Comes with a set of 12 identical 20 amp manual reset fuses so you can carry spares for multiple circuits or vehicles.
• Raised holder compatibility: The resettable design is better suited to raised fuse holders where the extra height is not a problem.

Who It's For

The kit is best for vehicle and boat owners who frequently troubleshoot electrical faults and prefer a reusable breaker over single-use fuses. It suits mechanics, RVers and DIY electricians who need a consistent 20 amp solution across multiple DC systems.

It is not ideal for someone who requires a full assortment of different ampere ratings, nor for installations where a low-profile, flush-mounted fuse panel cannot accept the slightly taller resettable blade without a raised holder.

Pros & Cons

Pros

• Reusable reset action reduces the need to carry multiple disposable fuses when investigating shorts.
• Rated for common automotive and marine voltages, so it fits many DC circuits from 12V to 32V.
• Compact T3 low profile blades work in standard ATM fuse blocks and are easy to replace in the field.

Cons

• They are taller than regular blades, so a raised fuse holder is recommended and some stock panels may not accept them.

Frequently Asked Questions

Will these fuses work in a 12V car?
Yes. They are rated for 12V systems and up to 28 VDC, so they are suitable for standard car electrical systems.

Do these replace standard disposable blade fuses?
They perform the same protective function but are taller and manually resettable, so they replace disposable blades only when the fuse holder can accept the extra height.

How many are included?
The kit includes 12 identical 20 amp manual reset blade fuses for spares or multiple circuits.
