Egis A-Series 10A Panel Mount Breaker | 3201-10

The Egis A-Series 3201-10 is a 10 amp single pole circuit breaker built for the kind of panel work we do every week. It's a magnetic-hydraulic design in a clean white toggle body, and it drops straight into a standard panel cutout. If you're wiring up a DC distribution panel or protecting an AC branch circuit, this is the little switch that stands between a nuisance and a burned harness. It's a small part with a big job.

Here's what sets a magnetic-hydraulic breaker apart from the cheap thermal kind. It trips on actual current, not on heat. A thermal breaker uses a bimetal strip that reacts to temperature, so a hot engine room can make it trip early and a cold morning can let it ride past its rating. The 3201-10 doesn't care. It's rated to stay accurate from -40 to 185 degrees Fahrenheit. So the breaker you set at 10 amps trips at 10 amps, whether you're running the Gulf in August or tied up at a Great Lakes marina in November.

This one's rated for 277 volts AC and 80 volts DC, which covers just about every circuit on a boat and plenty on a work truck. DC house loads, bilge pumps, electronics feeds, and 120 or 240 AC shore-power branches all fall inside that window. The toggle doubles as an on/off switch, so you can kill a circuit at the panel without pulling a fuse. That's handy when you're chasing a gremlin and want to isolate one leg at a time.

And because it's a manual-reset breaker, a trip isn't the end of your day. There's no digging through a spares box for the right fuse. You find the fault, fix it, flip the toggle back up, and you're running again. Out on the water, that difference matters. A fuse that blows at 2 AM ten miles out is a real problem. A breaker you just reset is a footnote.

The mounting is where Egis made this easy. It's a toggle panel mount that fits any standard panel already cut for A-Series or C-Series magnetic-hydraulic breakers. So whether you're adding a circuit to an existing Egis panel or building a new one, the cutout is the same. Connections land on No. 10-32 screw terminals, and it ships with stainless steel self-locking hardware, so your ring terminals stay tight through years of vibration. Egis even includes the mounting screws. Small thing, but it means you're not making a second trip to the hardware store halfway through an install.

Don't let the size fool you. This breaker has real interrupting muscle, 5,000 amps at 277 volts AC and 1,500 amps at 80 volts DC. That matters when you're protecting a circuit tied to a large paralleled battery bank, where a dead short can dump a frightening amount of current in an instant. A breaker with low interrupt capacity can weld itself shut or fail dangerously under that kind of fault. This one is built to open cleanly and safely. It's also rated for 6,000 operating cycles at full load, so it holds up whether it's an everyday switch or a set-and-forget protector.

It meets UL 1077, the standard for supplementary protectors, so it's the right part for protecting individual branch circuits inside a larger system. We reach for these on center-console rebuilds, sailboat DC panels, and fleet-vehicle upfits, anywhere you want per-circuit protection that resets with a flip instead of a fuse swap. Egis backs it with a 4 year warranty. For a part this critical, that kind of coverage tells you they trust their own build. And if you're not sure a 10 amp rating is right for your circuit, give us a shout. We'll help you size it to your wire gauge and load. Get the breaker rating matched to the wire, not the load's peak draw, and you'll avoid nuisance trips.
