El producto esta como se describe las especificaciones.

This has been used for a while now to protect my solar system. It's easy to disconnect panels and reconnect now.. I bought an 80 and 40

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

Thermal Marine type breakers are highly prone to Failure.So glad these are now available in the US.

I bought a 100a breaker to service a solar array, charging from an MPPT with a 100a maximum charging capacity. I'm using 2awg OFC on a 15ft run from charge controller to battery, with a breaker 5ft from the charge controller.The 100a breaker was in place for about a year, running at around 75a, with a rare, short spike to 97a one time, according to history logs. It ran fine during that period of time. I decided to increase my solar array to maximize my MPPT, and the average amps every day was reached about 92a, with an accurance reaching 100a. Not one single time did the breaker pop in it's use, and the whole thing just melted from the inside out one day with extended 95a+ current. Defects happen, so I didn't put too much thought into it.Since I had head room to grow with the cables I had, I decided to repurchase the same breaker, but in the 125a version, thinking it would be more resilient to amperage. Within 3 weeks, the 125a breaker melted worse than the 100a version did. It got so hot, it charred and melted the plastic black. And guess what? The 125a breaker still never tripped.I figured that something designed to be a safety device would be made more quality, but I guess not. This is a cheaper unit, but not if it doesn't do what it's supposed to do.Otherwise, yea. Super easy to install. Just not worth the money. Spend like $5 more and get a better one.Update: I bought and replaced two more under Amazon's 30 day return windown. Every single one of these failed in the same way. This time, I even bought a second MPPT charge controller to split the 100a input into two 50a inputs, with one going to each Charge controller.... the 125a breakers still melted and never tripped.Bonkers, really.

this product is perfect.

Exactly as described.
