It's rated for both AC and DC, trips on true current instead of ambient heat, and holds steady from 40 below to 185 degrees. If you're wiring a panel and want protection that behaves the same in any weather, this one earns its spot.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eA circuit breaker isn't glamorous gear. But when a bilge pump seizes or a chafed wire shorts against the hull, this little Egis A-Series breaker is what stands between a nuisance and a fire. The 3211-15 is a 15-amp single-pole magnetic-hydraulic breaker in a black panel-mount toggle body, rated for both AC and DC, and built to shrug off the heat, cold, and vibration that live inside a boat.\u003c\/p\u003e\n\u003cp\u003eHere's why the magnetic-hydraulic design matters on the water. A lot of cheaper breakers use a thermal element that reacts to heat, so they trip early when the engine compartment gets hot and trip late when it's freezing on a winter delivery. This one doesn't. It trips on actual current, and its behavior stays consistent from 40 below all the way up to 185 degrees Fahrenheit. So a breaker you set to protect a 15-amp circuit actually protects it, in July heat or January cold.\u003c\/p\u003e\n\u003cp\u003eThe dual AC\/DC rating is the other thing that makes it handy. It's good for 277 volts AC and 80 volts DC, so the same part covers your 12- or 24-volt house circuits and any AC branch coming off an inverter or shore-power panel. Fifteen amps is a common size for a run of nav electronics, a washdown or livewell pump, cabin lighting, or an accessory circuit at the helm. Wire it in, and the toggle doubles as your on-off switch for that circuit. Flip it down to kill power when you're working on the gear, flip it up to bring it back.\u003c\/p\u003e\n\u003cp\u003eWhen something does go wrong, it trips and stays tripped until you reset it by hand. No auto-cycling into a fault over and over. You find the problem, fix it, and flip the toggle back on. And because it's a manual-reset toggle, there's no separate switch to buy for that circuit.\u003c\/p\u003e\n\u003cp\u003eEgis rates this one for a 5,000-amp interrupt at 277 VAC and 1,500 amps at 80 VDC. That high interrupt number matters more than it sounds. If you've got several batteries paralleled into a big house bank, a dead short can dump a staggering amount of current in a heartbeat, and a breaker with low interrupt capacity can weld itself shut instead of opening. This one is built to open cleanly and safely even on a large, high-energy system.\u003c\/p\u003e\n\u003cp\u003eInstallation is straightforward. It drops into any standard panel cut for A-Series or C-Series magnetic-hydraulic breakers, and the mounting screws come in the box. Connections land on No. 10-32 screw terminals, and Egis ships it with stainless-steel self-locking hardware so your ring terminals stay tight through years of pounding and vibration. That corrosion resistance from the stainless matters in a salt environment, and self-locking means you're not chasing a loose lug every haul-out.\u003c\/p\u003e\n\u003cp\u003eOne note on sizing. This is the 15-amp version of the Egis A-Series toggle breaker, and the family runs a wide range of amperages in the same body and panel footprint. So if you're building out a panel, you can mix breaker values across your circuits and still keep a clean, uniform look, with every toggle the same size and style. Match the amperage to the wire gauge and the load on each circuit, not to the biggest thing you might ever plug in. A breaker protects the wire, so a 15-amp breaker belongs on a circuit wired to carry at least 15 amps.\u003c\/p\u003e\n\u003cp\u003eIt's built to UL 1077 as a supplementary protector and rated for 6,000 electrical cycles at full load, so it holds up to real switching duty, not just sitting there waiting for a fault. Egis backs it with a 4-year warranty. It's a small part, but it's the kind of small part you want to get right. If you're rewiring a panel or adding a circuit and you want protection that behaves the same in any weather, this is an easy call.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e15-amp continuous current rating, sized for nav electronics, pumps, lighting, and helm accessory circuits\u003c\/li\u003e\n  \u003cli\u003eMagnetic-hydraulic design trips on true current, not ambient heat, for consistent protection from -40 to 185 degrees Fahrenheit\u003c\/li\u003e\n  \u003cli\u003eDual AC\/DC rating of 277 Vac \/ 80 Vdc covers both DC house circuits and AC inverter or shore-power branches\u003c\/li\u003e\n  \u003cli\u003eToggle body doubles as an on-off switch, so you can isolate the circuit without a separate switch\u003c\/li\u003e\n  \u003cli\u003eManual reset holds the circuit open after a fault until you clear the problem and flip it back on\u003c\/li\u003e\n  \u003cli\u003eHigh interrupt capacity of 5kA at 277 Vac and 1.5kA at 80 Vdc for safe operation on large paralleled battery banks\u003c\/li\u003e\n  \u003cli\u003eNo. 10-32 screw terminals with stainless-steel self-locking hardware included for vibration-proof connections\u003c\/li\u003e\n  \u003cli\u003eDrops into standard panels cut for A-Series and C-Series magnetic-hydraulic breakers, mounting screws included\u003c\/li\u003e\n  \u003cli\u003eBuilt to UL 1077 and rated for 6,000 electrical cycles at full load\u003c\/li\u003e\n  \u003cli\u003eBlack single-pole housing backed by a 4-year Egis 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\u003eWhat's the difference between a magnetic-hydraulic breaker and a thermal one?\u003c\/summary\u003e\n    \u003cp\u003eA thermal breaker reacts to heat, so its trip point drifts as the surrounding temperature changes.
