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. ### ⭐⭐⭐⭐⭐ Use it for trolling motor setup *by R***E on Reviewed in the United States 🇺🇸 on May 10, 2014* 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 units *by K***K on Reviewed in the United States 🇺🇸 on June 28, 2017* Good quality unit, sturdy construction. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/14120549-cooper-bussmann-automotive-circuit-breaker-cb185-70a-42v](https://www.desertcart.hr/products/14120549-cooper-bussmann-automotive-circuit-breaker-cb185-70a-42v) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-04-23*
