It's a Type 3 manual reset, so it stays open after a trip until you reset it by hand. Rated to 28 volts DC for 12V and 24V systems, sealed to IP66, and fitted with stainless hardware, it's built to hold up around spray, washdown, and hot engine bays.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Egis Short Stop 4730-30 is a 30-amp marine circuit breaker built to protect a single DC circuit on your boat. It's a Type 3 manual reset design, which means when it trips on an overload it stays open until you push it back in by hand. No guessing whether a fault cleared itself. If this breaker pops, you know something drew too much current, and you get to find out why before you put the circuit back in service.\u003c\/p\u003e\n\u003cp\u003eWe reach for a 30-amp breaker like this one all the time when we're rigging accessory circuits. Think livewell pumps, bilge blowers, a bank of cabin lights, a stereo amp, or a windlass feed on a smaller boat. Anywhere you've run a feeder that needs its own overcurrent protection, a Short Stop sized to the wire and the load does the job. Match the breaker to the ampacity of the wire it's protecting, not just the device, and you're wiring it the way ABYC wants it done.\u003c\/p\u003e\n\u003cp\u003eSizing is simple. Pick the breaker that matches the wire gauge and the continuous load on the circuit, and never rate a breaker higher than the ampacity of the wire it feeds. A 30-amp Short Stop pairs naturally with the wire sizes common on mid-current accessory runs. If your load sits well under 30 amps but your wire is heavy, size to the wire. The breaker protects the copper first and the device second.\u003c\/p\u003e\n\u003cp\u003eVoltage rating is 28 volts DC, so it's happy on both 12-volt and 24-volt systems. That covers the vast majority of recreational boats and plenty of commercial rigs too. One part number, two common system voltages, less to stock in the parts drawer.\u003c\/p\u003e\n\u003cp\u003eThe build is made for life on the water. It carries an IP66 protection rating, so it's dust-tight and shrugs off strong jets of water. That's the kind of sealing you want when a breaker lives in a console, a bilge-adjacent panel, or an open helm that catches spray. It won't survive being fully submerged, but for splash, rain, and washdown it holds up fine. The operating temperature range runs from -40 to 185 degrees Fahrenheit, wide enough for a cold winter layup or a hot engine compartment in July.\u003c\/p\u003e\n\u003cp\u003eConnections are made through No. 10-32 stud terminals, and Egis includes stainless steel hardware to land your ring terminals on. Stainless is the right call here. Plated steel rusts, and a corroded connection on a DC feeder means voltage drop, heat, and eventually a failure right when you need the circuit. Stainless studs and nuts keep that joint clean season after season.\u003c\/p\u003e\n\u003cp\u003eThe housing is green, and it's a single-pole, single-circuit breaker, so it protects one run at a time. Mount it close to the source of power for the circuit it protects. The whole point of a breaker is to stop a fault before the wire downstream becomes the fuse, so keeping it near the panel or the battery feed is good practice.\u003c\/p\u003e\n\u003cp\u003eOne note on resettable protection versus fuses. A fuse is one and done. You blow it, you replace it, and you'd better have spares aboard. A manual reset breaker like this one lets you clear the fault and get back underway without digging through a fuse kit. For circuits you actually want back quickly, a windlass, a pump, or your nav electronics, that reset button earns its keep. Just remember, a breaker that keeps tripping is telling you something, so chase the root cause rather than holding the button down.\u003c\/p\u003e\n\u003cp\u003eShort Stop breakers have been a staple in marine and heavy-vehicle electrical work for years, and Egis Mobile Electric has been building this kind of gear for over 25 years. These are the parts fleet electricians and boat riggers trust because they reset cleanly, seal well, and don't quit. Whether you're replacing a tripped or corroded 30-amp breaker or building a new circuit from scratch, this is a straightforward, dependable choice.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e30-amp rating protects a single DC circuit sized to the wire and load\u003c\/li\u003e\n  \u003cli\u003eType 3 manual reset holds the circuit open after a trip until you reset it by hand\u003c\/li\u003e\n  \u003cli\u003e28-volt DC rating works on both 12-volt and 24-volt systems\u003c\/li\u003e\n  \u003cli\u003eIP66 sealed housing is dust-tight and resists strong water jets\u003c\/li\u003e\n  \u003cli\u003eOperating range of -40 to 185 degrees Fahrenheit handles winter layup through hot engine bays\u003c\/li\u003e\n  \u003cli\u003eNo. 10-32 stud terminals with included stainless steel hardware resist corrosion\u003c\/li\u003e\n  \u003cli\u003eSingle-pole, single-circuit design for straightforward branch protection\u003c\/li\u003e\n  \u003cli\u003eGreen Egis Short Stop housing built for marine and heavy-vehicle electrical work\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\u003eHow many amps is the Egis 4730-30 breaker rated for?\u003c\/summary\u003e\n    \u003cp\u003eIt's a 30-amp breaker meant to protect a single DC circuit.
