Review: Bonne qualité
Review: This product works great. Please ensure you are using ferrules to crimp the end of the copper stranded wires before making the connection, or crip tight with a copper tube end, this will in most case prevent overheating and allow for better flow current. Also if you are using a inverter with built in charge controller is best to use a non polorized switch. This breaker is performs best in my opinion where the battery , inverter and solar controller are seperate devices.

I have 3, 6 string solar panels run through to inverter. great for maintenance shut off, or when I occasionally need to feed batteries from a gas generator. Good product.
