They lock on a normal DIN rail, and are easy to remove if necessary. Wire clamps are fine. Make sure these are suitable for your application. They lack the certifications required for some purposes in the US. ### ⭐⭐⭐⭐⭐ Good quality and price. *by on Reviewed in the United States March 11, 2026* Using in a solar project system. These are for AC. Make sure if you are using these in the 120 volt ac portion of the project. For the DC side the breakers needed are marked for DC. Some DC breakers show polarity. Check to see that the DC solar voltage input is connected to the "+" terminal. on mine, this was on the bottom. ### ⭐⭐⭐⭐⭐ It's a circuit breaker and does what circuit breakers do. *by on Reviewed in the United States November 1, 2025* I bought this and a 10A breaker that I use to troubleshoot blown fuse components. ## Frequently Bought Together - KERWINN Miniature Circuit Breaker 120V/240V ac Circuit Breaker 1 Pole 20Amp Smart Circuit Breaker DIN Rail Mount for Marine Power Systems,Solar photovoltaic Systems(C20A) - MOLLOM 2 Way Circuit Breaker MCB Distribution Protection Box with DIN Rail, IP65 Waterproof,for Indoor and Outdoor - KERWINN Miniature Circuit Breaker 120V/240V ac Circuit Breaker 2Pole 32Amp Smart Circuit Breaker DIN Rail Mount for Marine Power Systems,Solar photovoltaic Systems(C32A) --- ## 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/536766457-miniature-circuit-breaker-120v-240v-ac-circuit-breaker-1-pole](https://www.desertcart.hr/products/536766457-miniature-circuit-breaker-120v-240v-ac-circuit-breaker-1-pole) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-06-24*
