Small size for those tough spots. I use these in solar installations! ### ⭐⭐⭐⭐⭐ Been in use in off grid solar for over 2 years going strong *by A***M on January 25, 2025* This has been in nonstop use since purchased and has worked as intended. Has not tripped yet but the max current in my system is around 60A. It opens the circuit even with 60A DC flowing through it when pulled manually. ### ⭐⭐⭐⭐⭐ go higher on the maximum input *by S***T on July 2, 2026* I’m using this on a solar electric system so from the solar panels to the batteries, the charge control controller outputs a maximum of 60 A so you want to use an 80 amp circuit breaker not a 60 the 60 will melt. These being made in China. They don’t use copper on the inside. They’re using aluminum always go higher. --- ## 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.sg/products/457361674-dc-miniature-circuit-breaker-2-pole-500v-80-amp](https://www.desertcart.sg/products/457361674-dc-miniature-circuit-breaker-2-pole-500v-80-amp) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-08-16*
