### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Works great / reasonable price
  

*by G***M on Reviewed in the United States on October 10, 2020*

Using it for van build electrical setup, the item shipped fast. I am using them directly on batteries and my terminal block. Great quality product, highly recommended.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Compact and simple
  

*by G***A on Reviewed in the United States on January 6, 2020*

I am using this on an 8-battery solar bank with each 2-battery series fused on the load side. This provides short circuit/overload protection at each module as close to the battery as possible. Having the fuse block on the battery also makes for a nice heat sink. The block and fuse are very compact and easy to install. Remember to account for a fused connection in your overall wire load/temp/size calculations - there are plenty of online calculators out there to make this calculation for you.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Great When Space is Limited
  

*by T***N on Reviewed in the United States on May 30, 2020*

The system I am building will be installed in a location where there just is not much space to spread out the components.  I have used these fuse blocks in two locations:  bolted directly to the positive lithium battery terminal (for a main system fuse) and on the output terminal of the main system switch (for a high amperage branch circuit).  I do not recommend attaching directly to a battery terminal if you are not using lithium batteries.  Other than space considerations the other reason I use these is because they have an ingress rating of IP66, so they can handle adverse environmental conditions.  The only downside of these MRBF fuses is that the replacement fuses are very expensive compared to MEGA/AMG fuses and especially the AMI/MIDI fuses.
