Blue Sea Systems 7189 285 Series Circuit Breaker, Surface Mount, 150 Amp, 48V DC

It was an easy install. To fit a 2/0 terminal, a washer was needed under the nut.Great tech support from the company.

Excellent compared to the cheaper ones. Easy to install.

I bought the 150A version. I ran the same test I did on the less expensive brands of these breakers. The other brands would trip around 80A to 90A (sometimes even less). This brand, I was able to run at 120A for about 45 minutes before I had to reduce the current because my test equipment was getting too hot. These actually appear to work at their rated current. Don't waste your money on the less expensive brands, get these if you are looking for breakers that actually meet their specifications. Also, the measured on resistance was about 0.0005 Ohms. Much better than other brands that I tested. Very nice pads around the studs for very low contact resistance.

Initially I was going to buy a less-expensive circuit breaker (maybe even a fused connection) for an inverter that I added to a diesel truck that I own. After looking into it, and looking at what some of the respected truck body/equipment manufacturers use, I went for this breaker. I like that I can hit the red button and shut the circuit off. I store the truck with this switch in the 'off' position just for added safety.I mounted it inside of the battery box of the truck on the side-wall of the box. Drilled through the steel in two places to mount it at the best angle.

Blue sea is one of my go to brands which has never failed me. Used the 7189 285 Series Circuit Breaker with Blue Sea Systems 5032 ST Blade Fuse Block for my accessories so i wouldn't have to tap into my fuse box.

Bolts are too small for most battery cables that are used in a solar charging system. Need more details in the product’s description. Luckily I make my own battery cables.

Original and that says it all! Highly recommended!

It just works- great product, good price, solid construction. And their cust and tech support is just fantastic. Very helpful and quick to offer support. I can't say enough good things about their tech support.
