Quality you can depend on.
It meets the expectations on both quality of manufacturing and functionality. Its a Bussmann. Enough said .

Easy to install and use.
Love this for high amp protection with my LIFEPO4 200amp batteries in our RV. Running at 150 amps there is a mild heat rise above ambient.

Does what it is supposed to
I looked all over and this was the only fuse I could find that attaches directly to the battery of my RV. I feel much safer with my 1500 watt inverter (that the positive battery cable has been known to pop out of) plugged into this that directly to the battery. To use this, you do need to buy the terminal fuse post from the same manufacture.

Now this is one of the products I never even knew existed it’s a main fuse that connects directly to your battery to protect any circuit I used for my power inverter absolutely fantastic will recommend

fuse
I use this fuse for an offroad truck wiring of some capacity to provide some electrical fault protection. So far works well and no issues. It fits a unique designed "mount/bracket"...

You have to tighten down to get proper contact
Like the fact you can see if the fuse has blown by side view. Previous brand you either had to use a ohm meter or remove it and it fell apart. I needed to tighten using inch pounds torque wrench to not over torque on my Lithium Lifepo4 battery, specified for my Discovery lithium blue battery.

Product was perfect, delivery was 5 days late
Product was perfect. Delivery was horrible. Took 5 days for a next Day Delivery. I’ve been having this issue since Amazon closed their warehouse in Quebec. Probably going to have to get my stuff directly from sellers. It’s too bad cause Amazon is a one stop shop!
