The correct answer is NO the widthe of the opening is 11/16 not 3/4 as used on the 4/0 c** A: i had to use a dremel with a zip bit to make room for the 4/0 lugs **Q: Inverter Manufacturer says I need a 400Amp Breaker between my battery and low frequency inverter! 1-pole I assume?** A: 2 pole is safer, as it interrupts both cables. I have had 2 units of the 400amp single pole fuse open (no current) without ever tripping. I would not trust these units with anywhere near their rated current, which makes them useless as a breaker. Just a giant switch.... **Q: What does it mean when it says no short circuit protection at 12-32v? It sounds non-functional.** A: Correct. They are no good as actual breakers, better off with a knife switch and fusible links! --- ## 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.be/products/449799650-dihool-heavy-duty-battery-disconnect-switch-300-amp-dc-circuit](https://www.desertcart.be/products/449799650-dihool-heavy-duty-battery-disconnect-switch-300-amp-dc-circuit) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-10-11*
