One rotary knob isolates a single bank, runs everything off either battery, or combines both to feed all loads. Rated to 32 volts, 175 amps continuous and 300 amps intermittent, and KEMA and UL approved.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe VETUS ACCUSCH is a heavy-duty battery selector switch built for boats running higher-voltage DC systems. It gives you one rotary control to isolate your battery banks, run everything off a single bank, or tie both banks together to feed all your loads. Four positions, two battery inputs, and a current rating that holds up to real marine use.\u003c\/p\u003e\n\u003cp\u003eWhat sets this one apart is the 32-volt rating. Most selector switches top out at 12 or 24 volts. This one is rated to 32V, which makes it a good fit for the higher-voltage house and propulsion systems you see on electric-drive boats and larger cruisers. It carries 175 amps continuously and handles 300 amps on an intermittent basis, so it's sized for house loads and combined-bank duty rather than momentary engine-cranking surges. If your setup sees short high-current start surges above that intermittent number, this isn't the switch for that job.\u003c\/p\u003e\n\u003cp\u003eThe four positions are straightforward. OFF kills all output. Position 1 runs everything off battery bank one. Position 2 runs everything off bank two. BOTH ties the two banks in parallel and feeds all loads from the combined capacity. That last position is how you give a tired starting bank a boost from the house bank, or how you charge both banks at once from a single source. It's the kind of simple, certain control you want when something's gone quiet on the water and you need power back fast.\u003c\/p\u003e\n\u003cp\u003eInstallation is simple, but do it right. The switch mounts on a panel or bulkhead near the batteries where you can reach it fast in an emergency. The terminals accept large battery lugs, so size your cable to the load. On longer runs at high current you'll see voltage drop, so step up a cable size if the switch sits more than a few feet from the bank. And snug the terminal hardware down properly. A loose connection on a high-current switch is exactly where heat and arcing start, and that's the last thing you want back near the batteries.\u003c\/p\u003e\n\u003cp\u003eOne thing to be clear about. This is a manual switch, not an automatic charging relay. It won't isolate your banks on its own, so you're the one deciding what feeds what. Label your panel clearly so anyone aboard can find the right position in a hurry. Leaving it in BOTH under a heavy load parallels the banks with no isolation between them. That's fine for combining and charging, but it means a weak or failing battery can pull down a healthy one. Switch back to a single bank when you want them truly separated. If you're running lithium, plan your bank protection to match.\u003c\/p\u003e\n\u003cp\u003eThe ACCUSCH is KEMA and UL approved, so it meets recognized safety standards for marine electrical gear. The black housing keeps it low-profile on a helm panel or tucked into an engine space. VETUS builds it as part of a complete DC system range, so it drops cleanly into a wider VETUS install and matches the rest of the gear on the boat.\u003c\/p\u003e\n\u003cp\u003eWho's this for? Anyone with a two-bank setup on a 32-volt boat who wants simple, certified control over isolation and combining. Trawlers, larger cruisers, and electric-drive boats all fit the bill. It's not the right pick for a small 12-volt runabout, and it's not a substitute for an automatic charging relay if hands-off bank management is what you're after. But for deliberate, manual control that you can trust, it does exactly one job and does it well.\u003c\/p\u003e\n\u003cp\u003eOne knob. Four positions. No guesswork. That's the whole idea, and after installing plenty of these, we still think that simplicity is the best thing about it.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e4 switching positions (OFF, 1, 2, BOTH) let you isolate a single bank, run off either battery, or combine both to feed all loads\u003c\/li\u003e\n  \u003cli\u003e175 amp continuous rating handles sustained house and system loads without overheating\u003c\/li\u003e\n  \u003cli\u003e300 amp intermittent rating gives you headroom for short high-draw moments when banks are combined\u003c\/li\u003e\n  \u003cli\u003eRated to 32 volts for higher-voltage DC systems that standard 12V and 24V switches can't cover\u003c\/li\u003e\n  \u003cli\u003e2 battery inputs support a classic two-bank house-and-reserve arrangement\u003c\/li\u003e\n  \u003cli\u003eKEMA and UL approved to recognized marine electrical safety standards\u003c\/li\u003e\n  \u003cli\u003eHeavy terminals accept large battery cable lugs for high-current runs\u003c\/li\u003e\n  \u003cli\u003eBlack housing stays low-profile on a helm panel or in an engine compartment\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized VETUS reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat do the four positions on the ACCUSCH switch do?\u003c\/summary\u003e\n    \u003cp\u003eOFF disconnects all output.
