DC Miniature Circuit Breaker, 2 Pole 500V 125 Amp Isolator for Solar PV System, Thermal Magnetic Trip, DIN Rail Mount, High Current DC Disconnect Switch MCB 2P C125

Bonne qualité

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.

I noticed several photos of this breaker where it had gotten hot or melted around one or more of the wire connect slots. The mechanism is supposed to open enough to clamp the wires inside the clamp\receptacle....but if you are paying close attention you can put wire in such a manner that a poor connection is made &\or the wire isn't correctly clamped. This will lead to reduced surface are for current to flow & can cause heating & heat damage even though the breaker itself doesn't hit its 80A limit & trip. The best method would be to solder & install ferrules on the wire ends & then make sure you open the clamp fully then insert ferrule & tighten very good....done correctly the breaker can handle its rating

The use is good. Qualities is good value for the money and it fits easily install installed easy install installation and protection level is great.
