Egis 4711-05 5A Push-To-Reset Circuit Breaker

The Egis Mobile Electric 4711-05 is a 5-amp push-to-reset circuit breaker made for clean panel mounting on a boat. It guards a single circuit up to 50 volts DC, and the moment it trips, the button pops out so you can see at a glance which circuit faulted. Press it back in and you're running again. No spare fuse to dig for in a drawer, no crimping a new link at the worst possible moment.

What sets this one apart from the screw-terminal version in the same line is the spade terminal. You crimp a female quick-connect onto your wire and slide it straight on, with no ring terminal to fish under a screw head. For a 5-amp accessory circuit that's a fast, tidy connection, and it makes swapping a lead later a two-second job. Quick-connects also make troubleshooting easier, since you can pop a lead off to isolate a circuit without unscrewing anything. The knurled nut and palnut handle the panel mounting, so you get a snug, vibration-proof fit on a dash or breaker panel without extra brackets, and the stainless hardware holds up to salt air.

Five amps is the small end of the panel. Think nav light circuits, instrument feeds, a single fishfinder or chartplotter on standby, bilge pump float switches, a stereo head unit, or an accessory USB bank. For a 5-amp load, 16-gauge wire is a sensible practical minimum, and 18-gauge is fine on a short run. The breaker sits inline between your bus or switch and the device, and it opens before the wire ever gets hot if something downstream shorts or pulls too much current. Because it's a thermal breaker, it rides out a brief startup surge and only opens on a real sustained overload, so you don't get the nuisance trips a fast fuse can give you on inrush.

Here's why we like push-to-reset breakers over fuses on a working boat. A blown fuse needs a replacement, which means carrying spares in the right amp ratings and finding them in a pitching cabin. A breaker just needs a thumb. When this one trips, the popped button is also your diagnosis. You know instantly which circuit had the problem instead of pulling fuse after fuse to find the dead one. For circuits you touch often, that convenience adds up over a season.

The 50-volt DC rating means this breaker is happy on any common boat system, whether that's 12-volt, 24-volt, 32-volt, or even a 42-volt setup. And it's ignition protected, which matters more than it sounds. That rating means it won't throw a spark that could set off fumes, so it's safe to mount in an engine compartment or a battery box where gasoline vapor can collect. A lot of cheaper breakers skip that certification. Egis builds it in.

The UL1500 listing is the ignition-protection standard, and the IP40 front rating keeps fingers and larger debris out of the face. The back of the breaker is IP00, so the terminals are open. If you're mounting it somewhere exposed to spray, a sealing boot is available separately to cover the front, and we'd recommend one for a console that catches weather. Operating range runs from 14 to 140 degrees Fahrenheit, which covers just about any helm or compartment you'd put it in.

Installation is straightforward for anyone comfortable behind a dash. Drill the mounting hole, drop the breaker through, and secure it with the knurled nut from the front and the palnut behind the panel. Land your supply wire on one spade and the load wire on the other. That's it. First-time owners wiring up a small accessory panel and seasoned riggers building out a full helm both reach for these, because they're cheap, dependable, and they take the guesswork out of resetting a tripped circuit. Keep the crimps clean and give each spade a light tug to confirm it's seated, and this little breaker will protect that circuit for years without a second thought.
