### ⭐⭐⭐⭐⭐ 







  
  
    Good DC Circuit Breakers/Disconnect
  

*by V***L on Reviewed in the United States on March 22, 2021*

It took a while for these to arrive (ships from China), but the circuit breaker work as advertised. Easily mount in a DIN Rail Enclosure and are great for disconnecting solar panels (or other DC loads) for service or test and at the same time provide overload/short circuit protection for the wiring

### ⭐⭐⭐
