This Relaxn inline blade fuse holder gives you a simple way to protect a 12 volt circuit up to 30 amps without rewiring a whole loom. You just cut the positive cable drop the standard blade fuse in and close the waterproof cap. The compact body works well near batteries switches or small loads like pumps and lights where space is under the pump or seat. The holder comes in a bright red housing so you can spot the fuse point quickly when you are chasing an issue under a deck or behind a panel. The wiring and body are made to suit currents up to 30 amps so it sits nicely on most accessory lines. It is a smart buy if you want separate protection on each bit of gear instead of loading everything into one panel.

Q: What type of fuse does this holder accept?

It accepts a standard automotive-style blade fuse. That means the same straight-blade fuses used in most 12 V fuse boxes. You can match the amp rating of the fuse to your gear up to a 30 amp maximum. Mini or maxi blade fuses will not sit correctly in this size holder.

Q: Can I use this fuse holder on non-marine 12 V setups?

Yes it can be used on general 12 V circuits within its 30 amp rating. Many people run them in campers trailers and vehicles as well as boats. The waterproof body is simply an advantage in dusty or damp spots. Just be sure the cable size you connect is suitable for the load.

Q: Is the fuse holder supplied with a fuse?

No the holder is supplied on its own without a fuse. This lets you choose the correct amp rating for your circuit. Always select a fuse that matches the cable size and the device draw. Using your own stock also keeps spares consistent across the rest of your setup.

Q: Where should I position this inline holder in a circuit?

The holder is best placed in the positive feed to the accessory. Many users keep it as close to the power source as the layout allows. That way the cable run is protected for most of its length. Keep the cap accessible so you can check or swap the fuse without pulling panels apart.
