It protects a single 10-amp accessory circuit, trips on an overload, and resets with a push once you've sorted the fault. Red blades tell you the rating at a glance, and the 28-volt DC rating covers both 12 and 24-volt systems.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eIf you've wired up an Egis MT Series block, you already know the appeal. One sealed, connectorized hub for your accessory circuits instead of a rat's nest of inline fuse holders. The 472010 is the 10-amp breaker that fills one of those positions. It's a blade-style unit, so it seats into the block the same way a blade fuse would, but instead of blowing and needing a replacement, it trips and resets.\u003c\/p\u003e\n\u003cp\u003eThat's the real difference between a breaker like this and a plain fuse. When a 10-amp circuit pulls too much current, say a pump stalls or a wire chafes through to ground, the breaker opens and kills power to that leg. No melted fuse, no digging through the glovebox for a spare at the worst possible moment. You find the fault, fix it, and push the breaker back in. It's manual reset, which is what you want on a boat. An auto-reset breaker would keep cycling power back onto a dead short, and that's how you cook wiring. Manual reset makes you deal with the problem before the circuit goes live again.\u003c\/p\u003e\n\u003cp\u003eThe red blades aren't just for looks. Blade color follows the same amp-rating code boaters already know from standard blade fuses, and red means 10 amps. So when you're staring at a populated MT block trying to remember which leg feeds the livewell pump, the color tells you the rating without pulling anything. It's a small thing that saves real time during a dockside troubleshoot.\u003c\/p\u003e\n\u003cp\u003eRated at 28 volts DC, the 472010 is happy on a 12-volt system or a 24-volt one. Ten amps is a sensible size for a lot of common loads. Nav lights, a cabin fan, a small bilge or livewell pump, a stereo head unit, or a cluster of USB and 12-volt outlets. Match the breaker to the wire and the load, not the other way around. If you're running close to 10 amps continuous, you'll want to be on 16-gauge wire at short runs or step up to 14-gauge as the run gets longer, in line with ABYC practice.\u003c\/p\u003e\n\u003cp\u003eThe MT Series blocks these breakers live in are sealed units built for life on the water, with stainless hardware and connectorized terminals that keep corrosion out of your connections. Running breakers in the block instead of scattered inline holders means every protected circuit lands in one spot. When something trips, you walk to one place and look, instead of chasing fuse holders zip-tied behind the dash.\u003c\/p\u003e\n\u003cp\u003eInstalling one is about as simple as marine wiring gets. With the block powered down, seat the breaker into its position until it's fully home, then land your load wire per the block's layout. There's nothing to calibrate and no polarity to fuss over on the breaker itself, though you'll of course keep your block's feed and grounds correct. Because it's part of the sealed block system, you're not adding another weatherproof fuse holder to find a home for, and that's one fewer failure point out where spray and humidity do their worst.\u003c\/p\u003e\n\u003cp\u003eA quick word on what this isn't. It's not a main battery breaker or a high-amp panel breaker. Ten amps is a branch-circuit size, meant to protect a single accessory leg, not your whole house bank or a windlass. And it's not a stand-in for correctly sized wire. A breaker protects the wire from overheating, so the rating has to suit the conductor. Size it right and it'll sit quietly for years and only ever trip when something's genuinely wrong.\u003c\/p\u003e\n\u003cp\u003eThis listing is for a single 472010 breaker. If you're populating a fresh block or carrying spares in different ratings, order the amperages you actually need for each leg. Egis has been building marine and specialty-vehicle electrical gear for over 25 years, and this breaker is a representative piece of that. Simple, sealed-system friendly, and honest about what it does. If your MT block has an open 10-amp position, this is the part that fills it.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e10-amp rating protects a single accessory branch circuit against overload and short faults.\u003c\/li\u003e\n  \u003cli\u003e28-volt DC rating covers both 12-volt and 24-volt marine systems.\u003c\/li\u003e\n  \u003cli\u003eManual reset keeps a tripped circuit off until you've found and fixed the fault, then pushes back in.\u003c\/li\u003e\n  \u003cli\u003eBlade-style form factor seats directly into Egis MT Series Sealed Fuse Blocks, no inline holder needed.\u003c\/li\u003e\n  \u003cli\u003eRed blades follow standard blade-fuse color coding, so the 10-amp rating reads at a glance.\u003c\/li\u003e\n  \u003cli\u003eResettable design replaces blow-once fuses, so there's no spare to dig for after a nuisance trip.\u003c\/li\u003e\n  \u003cli\u003eBuilt for the sealed MT block system, keeping protected circuits consolidated in one corrosion-resistant hub.\u003c\/li\u003e\n  \u003cli\u003eSold as a single breaker, so you populate each block position with the exact amperage that leg needs.\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 Egis Mobile Electric 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 amperage is this Egis breaker?\u003c\/summary\u003e\n    \u003cp\u003eIt's a 10-amp breaker.
