## Customer Reviews

### ⭐⭐⭐⭐ 







  
  
    Nice Fuse; Terminal Studs Seem Undersized.
  

*by L***. on Reviewed in the United States on February 8, 2020*

The 1/4" terminal studs are, IMHO, too small for a 300 amp protection device. The 1/0 AWG battery cable I landed on said terminal studs has a 3/8" heavy lug, so it's a missmatch. Working so far but I haven't had any big current surges either. Would be 5-star item but for this "issue".

### ⭐ 







  
  
    blows off after 100A
  

*by A***D on Reviewed in the United States on February 23, 2020*

dear purchaser if you are planing to connect it to a device that takes more then 100A the breaker will open and you need to result it manual , so its a misleading the 300A.  NOT recommended .

### ⭐⭐⭐⭐⭐ 







  
  
    Working real good I'm putting 320 amps through it
  

*by D***E on Reviewed in the United States on July 18, 2020*

Works great
