It's rated for both AC and DC, resets by hand with a flip of the toggle, and drops into any standard A-Series or C-Series breaker panel. Stainless self-locking hardware keeps it tight through years of engine-room vibration.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Egis Mobile Electric 3211-05 is a 5-amp single-pole circuit breaker made to live in your boat's panel and protect one circuit the right way. It's a magnetic-hydraulic breaker, which is the type most marine electricians reach for when they want a trip that behaves predictably in real conditions. You mount it through a standard panel cutout, wire it in line, and it guards that branch against short circuits and sustained overloads. When something goes wrong, the toggle pops. When you've fixed the problem, you flip it back by hand. No fuse to hunt for in a drawer, no spare to buy.\u003c\/p\u003e\n\u003cp\u003eHere's why the magnetic-hydraulic design matters out on the water. A thermal breaker leans on a bimetal strip, so its trip point drifts with the ambient temperature. Cold morning, hot afternoon, engine room baking at anchor. That means a thermal breaker can nuisance-trip when it's warm or let too much through when it's cold. This one uses a coil and a hydraulic delay instead, so the trip curve stays consistent from -40 to 185 degrees Fahrenheit. That's the kind of range you actually see between a winter layup and a summer engine compartment, and the breaker doesn't care.\u003c\/p\u003e\n\u003cp\u003eIt's rated for both AC and DC, up to 277 volts AC or 80 volts DC. That dual rating is handy on a modern boat where you've got a 12 or 24 volt house system plus shore power or an inverter feeding AC loads. One breaker family covers both sides of the panel, so you're not stocking two different parts. Continuous current here is 5 amps, which suits smaller branch circuits: nav electronics, a bilge pump, cabin lighting, a stereo head unit, an accessory feed. Match the breaker to the wire gauge and the load, and you've got proper protection instead of an oversized fuse that lets your wiring cook before it blows.\u003c\/p\u003e\n\u003cp\u003eThe interrupt capacity is where this breaker earns its keep on a bigger rig. It'll safely break 5,000 amps at 277 VAC and 1,500 amps at 80 VDC. If you've wired up a large paralleled battery bank, the available short-circuit current can be enormous, far more than a light-duty breaker can clear without welding itself shut or arcing. High interrupt capacity means that in a dead-short fault, this breaker opens the circuit cleanly and safely. It's also built to UL 1077 and rated for 6,000 operating cycles at full current, so it holds up to years of flipping on and off.\u003c\/p\u003e\n\u003cp\u003eInstallation is straightforward. The 3211-05 drops into any standard panel built to accept A-Series and C-Series magnetic-hydraulic breakers, so whether you're adding a circuit to an existing helm panel or building one from scratch, the cutout and spacing already line up. It ships with stainless steel self-locking mounting hardware, so the screws won't back out when the hull is pounding through a chop. The terminals take a No. 10-32 screw, giving you a solid, serviceable connection you can torque down and trust. The black toggle handle sits flush with a clean panel and gives you an at-a-glance on\/off plus a manual reset all in one.\u003c\/p\u003e\n\u003cp\u003eWho's this for? Any boater wiring or rewiring a DC or AC branch circuit who wants breaker protection instead of blade fuses. Riggers building custom helm panels. Anyone chasing down a nuisance-tripping thermal breaker who wants something more stable. It's a single-pole, 5-amp unit, so it protects one circuit at a modest load. If you need more amperage or a two-pole setup, step up within the A-Series to the right rating. Egis backs it with a 4-year warranty, and they've been building vehicle and marine electrical gear for over 25 years, so you're getting a part that's meant to be installed once and forgotten. That's exactly what you want from circuit protection.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e5-amp continuous current rating, sized for smaller branch circuits like nav electronics, bilge pumps, cabin lights, and accessory feeds\u003c\/li\u003e\n  \u003cli\u003eMagnetic-hydraulic trip mechanism holds a consistent trip point from -40 to 185 degrees Fahrenheit, so it won't nuisance-trip in a hot engine room or drag in the cold\u003c\/li\u003e\n  \u003cli\u003eDual AC\/DC rating up to 277 VAC and 80 VDC covers both your house DC system and shore-power or inverter AC loads\u003c\/li\u003e\n  \u003cli\u003eHigh interrupt capacity of 5,000A at 277 VAC and 1,500A at 80 VDC clears dead-short faults safely, even on large paralleled battery banks\u003c\/li\u003e\n  \u003cli\u003eSingle-pole manual-reset toggle pops on a fault and flips back by hand once you've fixed the problem, no spare fuse needed\u003c\/li\u003e\n  \u003cli\u003eFits any standard panel built for A-Series and C-Series magnetic-hydraulic breakers, so it drops straight into existing helm panels\u003c\/li\u003e\n  \u003cli\u003eStainless steel self-locking mounting hardware included, so the screws stay put through vibration and pounding seas\u003c\/li\u003e\n  \u003cli\u003eNo. 10-32 screw terminals give you a serviceable, torque-down connection you can trust\u003c\/li\u003e\n  \u003cli\u003eBuilt to UL 1077 and rated for 6,000 operating cycles at full current for long service life\u003c\/li\u003e\n  \u003cli\u003eBacked by a 4-year Egis Mobile Electric warranty\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\u003eIs the 3211-05 rated for both AC and DC circuits?\u003c\/summary\u003e\n    \u003cp\u003eYes.
