Egis 4711-07 7A Push-To-Reset Circuit Breaker

The Egis Mobile Electric 4711-07 is a 7-amp thermal circuit breaker that mounts right through your switch panel and resets with the push of a button. It's a cleaner answer than an inline fuse for any circuit you expect to work on. When the breaker trips, the button pops out so you can see exactly which circuit faulted, and a firm press puts it back in service. No fuse holder to open, no spare fuse to hunt for in a rolling locker, no corroded blade to pry out at the worst possible moment.

Seven amps is a handy mid-range rating. It's a good fit for a run of cabin or courtesy lights, a bilge blower, a small electronics feed, a stereo head unit, or an accessory circuit that draws a little more than a nav light but nowhere near a windlass. As a thermal breaker, it rides out the brief inrush when a motor or lamp first wakes up and only trips on a sustained overload, so you won't get nuisance trips every time a pump kicks on.

This one uses spade terminals, the flat quick-connect tabs that take a standard female push-on crimp. If you're wiring a panel where you'd rather slide connectors on and off than chase a screwdriver behind the dash, the spade style makes service quick. Crimp a female quick-connect onto your wire, give it a tug to confirm the crimp bit down, and push it onto the tab. Swapping the breaker later is a two-second pull, with no terminal screws to back out.

The 4711-07 is rated to 50 volts DC, which comfortably covers every common boat system. Twelve volt, 24 volt, 32 volt, even a 42-volt lithium bank all sit under that ceiling. One breaker handles whatever your DC architecture looks like, so you're not stocking different parts for different voltages.

It's ignition protected, too, which matters more than a lot of boaters realize. That rating means the breaker won't throw an arc capable of igniting gasoline vapor, so it's safe to mount in an engine space, a battery compartment, or anywhere fuel fumes can collect. If you've got a gas inboard or a portable tank aboard, ignition protection isn't optional, it's an ABYC expectation.

The protection ratings read UL1500, IP40 at the front face, and IP00 at the rear terminals. In plain terms, the front of the breaker shrugs off dust and incidental splash where it faces out through the panel, while the back, where your spade connections live, needs to sit in a dry, protected space behind the dash. A sealing boot is available separately if you want to dress the front face in an exposed location. It doesn't come in the box.

Egis ships it with the mounting hardware you need to do the job right. You get a knurled nut, a palnut, and stainless steel hardware, so it locks down clean through a panel cutout and stays put through vibration and trailering. Drill the hole, drop the breaker through, snug the knurled nut from the front, and lock it with the palnut behind. The stainless resists the salt-air corrosion that eats plated hardware alive.

For a 7-amp circuit, 16-gauge wire is the practical minimum, and on a short run it carries the load comfortably. Step up to 14-gauge if the run is long or you want margin against voltage drop. The 4711-07 is rated for operating temperatures from 14 to 140 degrees Fahrenheit, so it handles a cold spring launch and a hot engine bay alike. It protects a single circuit, so plan one breaker per protected feed. Build a six-switch panel and you'll want six of these, each sized to its load. It's a small part that does one job and does it honestly, which is exactly what you want standing between your battery and your wiring.
