Cooper Bussmann Automotive Circuit Breaker, CB185, 70A, 42V

I have 4 deep cycle batteries I've been using for powering 12V wenches as well as an inverter. I wanted to be able to isolate the batteries from each other in case 1 battery went bad and shorted, as well as protect batteries from an external short. Currently using a 100 amp battery charger but eventually I will be installing several solar panels for charging.This so far seems perfect for the job. I connected each battery to it's own breaker then connected output of each breaker together. I connect to the output of the breakers for power as well as for charging batteries. This also works as an on/off switch as well, with a push of the breaker button the breaker disconnects the battery, push the side lever and breaker is reset to on.The only thing I wish was different is the tab next to the breaker's posts, it limits the angle you can connect the wire to the post. Without the tab there I could use a straight copper buss bar to connect all of the outputs instead of needing something that loops around it.

Great protection for a trolling motor. Like that it has a reset which doubles as a quick disconnect at the batteries. Not sure of its longevity in marine service but batteries are in an enclosure. No issues through one full season.

Good quality unit, sturdy construction.

Great way to protect your audio system and great way to shut off the power while working with amps and power wires safetly

Quality. No problems with this. Swapped it in place of the painless fuse.

The safest way to cut power and save your life.

Bought this to put on my weeder. . Runs great. I bought another on for my second weeder,

works for my solar system
