Reviewed in the United States on January 8, 2024
The circuit breaker was installed between the inverter and two 12.7 volt batteries connected in parallel.
The power draw was measured to be 1650 watts. The battery voltage immediately dropped to 11.5v when the kettle was turned on. That is a current draw of about 143 amps from the battery. Which is about 120% of the circuit breaker's rating. It took 5 minutes for it to trip. That is close to what the chart on the box specify. So it does what it is supposed to do.
Did not test whether it is water proof
First, if the fuse blows, no need to have to get another one. The breaker is just tripped. Also, and more importantly, it gives the ability to “switch” off the power, or open the connection. Makes it easy to work on components by flipping the switch, then turning back on by just clipping it back in. Easy.
For those that bought the 250 amp like I did, that one doesn’t come with a switch. But get one that has an onboard switch that makes it easy to open the connection. Is a lifesaver.
Also, best point about THIS one over any other one is the 3/8” lug connection. Way beefier and more contact surface to flow the energy across to what you need. Everything else is 1/4” or 5/16”, so this is the king of connection at 3/8”.
Stop looking around. This is what you want. Trust me.
