Egis 4710-10 10A Push-To-Reset Circuit Breaker

The Egis Mobile Electric 4710-10 is a 10-amp push-to-reset circuit breaker built to protect a single branch circuit on your boat. Panel mount, screw terminal, and sized for the everyday loads that keep a helm running. Think nav lights, an electronics feed, a small washdown or bilge pump, an accessory bus. It sits behind the dash, does its job quietly, and lets you know the moment something's wrong.

Here's how it earns its spot. When a circuit pulls more than 10 amps for too long, the breaker trips and the button pops out. You can see it. No guessing which fuse blew, no digging through a fuse block with a flashlight. Once you've sorted out the fault, you push the button back in and you're back in business. That's the whole appeal of a push-to-reset breaker over a one-time fuse. It's reusable, and it's obvious.

The voltage rating is 50 volts DC, which covers just about every DC system you'll find on a boat. 12-volt, 24-volt, 32-volt, even a 42-volt setup all sit comfortably under that ceiling. So whether you're wiring a small center console or a larger cruiser with a 24-volt house bank, this breaker fits the picture.

Egis built this one for the marine environment, and it shows in the hardware. The mounting kit uses a knurled nut, a palnut, and stainless steel hardware, so it won't seize or corrode the way plated steel does once salt air gets to it. The terminal screws are self-locking, which matters more than it sounds. Boats vibrate. Engines shake. Trailer roads pound. Self-locking screws stay put instead of backing out and leaving you with an intermittent connection that's miserable to chase down.

One feature worth calling out is that it's ignition protected. That means it's safe to install in a closed compartment where explosive gases might collect, like a battery box or an engine space. A breaker that isn't ignition protected can throw a small arc when it trips, and in the wrong compartment that's a real hazard. This one is designed so it won't be the spark. If you're mounting near batteries or fuel, that rating is the difference between a legal, safe install and one that isn't.

The protection ratings are UL1500, IP40 on the front, and IP00 on the rear terminals. In plain terms, the front face keeps out fingers and larger debris, while the back where your wires land has no sealing on its own. That's normal for a panel-mount breaker. If your install spot sees spray or splash, Egis offers a sealing boot as an option to cover the works. The boot isn't included in the box, so add one to your order if you need the extra protection. Operating temperature runs from 14 to 140 degrees Fahrenheit, which covers cold mornings at the ramp through a hot engine compartment in summer.

Sizing is simple. Match the breaker to the circuit it protects, and size your wire to carry the load. For a 10-amp circuit, 16-gauge wire is a common minimum, but run length and load both push that number, so check your ampacity against ABYC guidance for the run you're making. The breaker protects the wire, not the other way around, so getting the pair right keeps everything safe.

This is a single-pole breaker, so it protects one circuit. If you're building out a panel with several protected feeds, you'll want one of these per circuit. It's a clean, honest piece of marine electrical gear that does exactly what it says and nothing it doesn't. For a first-time rewire or a seasoned refit on any boat, it's an easy, honest call.
