Good DC Circuit Breakers/Disconnect

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
