The red toggle doubles as an on\/off switch, it's rated for both AC and DC, and it drops into any standard A-Series or C-Series panel cutout. Stainless self-locking hardware and a UL 1077 listing mean dependable per-circuit protection that holds up on the water.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Egis Mobile Electric A-Series circuit breaker is a 5-amp, single-pole, magnetic-hydraulic breaker built to protect one DC or AC circuit on your boat. It drops into any standard panel cut for A-Series or C-Series breakers, and the red toggle doubles as an on\/off switch, so a single device handles both circuit protection and manual control. If you're wiring a nav light run, a bilge pump, an electronics feed, or any other low-draw circuit that needs its own dedicated protection, this is the kind of part that quietly does its job for years.\u003c\/p\u003e\n\u003cp\u003eHere's why the magnetic-hydraulic design matters. Unlike a simple thermal breaker that trips based on how hot a bimetal strip gets, a magnetic-hydraulic breaker senses actual current through a solenoid coil. That makes its trip point far more consistent across a wide temperature range. On the water, that's a real advantage. A thermal breaker sitting next to a warm engine can nuisance-trip on a hot day, or run sluggish when it's freezing. This Egis breaker holds its 5-amp trip point from -40 to 185 degrees Fahrenheit, so it behaves the same in a Maine winter as it does in a Florida August.\u003c\/p\u003e\n\u003cp\u003eThe AC and DC rating is what makes this breaker so flexible. It's rated to 277 volts AC and 80 volts DC, which covers everything from a 12-volt house circuit to a 48-volt battery bank to AC branch circuits. One part number, a lot of jobs. And because it carries a UL 1077 listing as a supplementary protector, it's the right tool for protecting a specific downstream circuit, not the main service feed.\u003c\/p\u003e\n\u003cp\u003eInterrupt capacity is a spec plenty of folks overlook, and it's where this breaker earns its keep on bigger systems. It'll safely interrupt 5,000 amps at 277 Vac and 1,500 amps at 80 Vdc. That high number matters when you've got large paralleled battery banks with a lot of available fault current. If a wire chafes through to ground on a system like that, you want a breaker that can open the fault cleanly instead of welding itself shut. This one's built for it.\u003c\/p\u003e\n\u003cp\u003eInstallation is straightforward. The breaker uses No. 10-32 screw terminals, so you land ring terminals under the screws and torque them down, no special crimp tools or proprietary connectors needed. It ships with stainless steel self-locking hardware, which is the detail that separates gear that survives on a boat from gear that doesn't. Stainless won't rust in a damp bilge or a spray-soaked console, and the self-locking feature keeps the connection tight through years of vibration. Loose terminals are a top cause of hot connections and voltage drop, and this hardware is designed to prevent exactly that.\u003c\/p\u003e\n\u003cp\u003eIf you've ever built or rewired a DC panel, you know the frustration of mixing breaker footprints. This one accepts the standard A-Series and C-Series magnetic-hydraulic mounting pattern, so it sits flush and lines up cleanly in a factory panel or a custom build. The included mounting screws mean you're not hunting through the fastener bin mid-install. Wire it in, tighten it down, and the red toggle gives you a clear read on circuit state at a glance.\u003c\/p\u003e\n\u003cp\u003eWho's this for? Anyone building or maintaining a marine electrical system that needs dependable per-circuit protection. Boatbuilders speccing panels, riggers upgrading an older DC distribution setup, and hands-on owners adding a new accessory circuit will all find this an easy, honest choice. It's rated for 6,000 electrical cycles at rated current, so it'll take years of daily switching without wearing out. And it's backed by a 4-year warranty from Egis, a company that's built motor-vehicle and marine electrical gear for over 25 years.\u003c\/p\u003e\n\u003cp\u003eA couple of things to keep in mind. This is a 5-amp breaker, so size it to the circuit you're protecting. Match the breaker rating to your wire gauge and load, don't just drop a 5-amp on a 20-amp run. And it's a supplementary protector under UL 1077, meaning it's designed to guard a branch circuit downstream of your main protection, not to serve as the primary service disconnect. Wire it correctly and it'll give you clean, reliable protection for the life of the boat.\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, single-pole protection for one dedicated DC or AC circuit\u003c\/li\u003e\n  \u003cli\u003eMagnetic-hydraulic trip mechanism holds a consistent trip point from -40 to 185 degrees Fahrenheit, no nuisance trips in heat or cold\u003c\/li\u003e\n  \u003cli\u003e277 Vac \/ 80 Vdc rating covers 12V, 24V, and 48V DC systems plus AC branch circuits\u003c\/li\u003e\n  \u003cli\u003e5kA at 277 Vac and 1.5kA at 80 Vdc interrupt capacity safely clears faults on large paralleled battery banks\u003c\/li\u003e\n  \u003cli\u003eUL 1077 listed supplementary protector for downstream branch-circuit protection\u003c\/li\u003e\n  \u003cli\u003eNo. 10-32 screw terminals accept standard ring terminals, no proprietary connectors\u003c\/li\u003e\n  \u003cli\u003eStainless steel self-locking hardware resists corrosion and stays tight through vibration\u003c\/li\u003e\n  \u003cli\u003eFits standard A-Series and C-Series magnetic-hydraulic panel cutouts, mounting screws included\u003c\/li\u003e\n  \u003cli\u003eRed toggle actuator doubles as a manual on\/off switch and shows circuit state at a glance\u003c\/li\u003e\n  \u003cli\u003eRated for 6,000 electrical cycles at rated current for years of daily switching\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 this circuit breaker rated for both AC and DC?\u003c\/summary\u003e\n    \u003cp\u003eYes.
