( add 10 am;s to your charger rating) ### ⭐ Cheap Junk *by M***. on June 27, 2024* I purchased this for my boat’s wash down pump. Anybody who has owned a boat knows accessibility to wiring is limited and you have to be a contortionist to work on it. I got it installed and NO POWER! Took it back out and checked continuity with my OHM meter and notta. Complete junk and I am installing a traditional fuse instead! --- ## 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/600021757-nilight-40a-inline-circuit-breaker-resettable-12-24v-dc-manual](https://www.desertcart.hr/products/600021757-nilight-40a-inline-circuit-breaker-resettable-12-24v-dc-manual) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-14*
