Egis 4730-10 Short Stop 10A Manual Reset Breaker
Egis 4730-10 Short Stop 10A Manual Reset Breaker — Product description
The Egis Mobile Electric 4730-10 Short Stop is a 10 amp manual reset circuit breaker built for marine and specialty vehicle wiring. Type 3 manual reset, 28 volt DC rating, IP66 sealed, and stainless steel hardware make it a clean choice for protecting a low-draw accessory circuit at the helm or on the dash.
If you've ever chased down a blown fuse behind a dash panel while the boat's rocking at the dock, you already know why a manual reset breaker earns its spot. The Egis Mobile Electric 4730-10 Short Stop is a 10 amp circuit breaker that trips on an overload and then waits for you to push it back in. No spare fuses to hunt for. No fumbling in a tackle drawer with a headlamp. You clear the fault, press the button, and you're back in business.
This is the 10 amp rating in the Short Stop line, color coded red so you can tell it apart from the higher amp versions at a glance when you've got a few of them mounted side by side. It's a Type 3 manual reset, which means it stays tripped until you physically reset it. That's the behavior you want on a circuit where a repeat trip tells you something's actually wrong, a chafed wire, a stuck pump, a shorted accessory. A self-resetting breaker would just keep cycling and hide the problem. This one makes you look.
The 4730-10 is rated for 28 volt DC service, so it covers both 12 volt and 24 volt systems without any drama. That's the standard way marine breakers get spec'd. The DC voltage rating is the ceiling, and running it on a 12 volt house circuit or a 24 volt bank both fall comfortably under it. Ten amps is a sensible size for a lot of small helm loads. Think nav lights, a VHF radio, a livewell pump, a stereo head unit, a set of courtesy lights, or a single electronics feed. Match the breaker to the wire gauge it protects, not to the appliance. The breaker's job is to open before the wire overheats, so size it to the conductor per ABYC practice and you're doing it right.
Egis built this one to live in a wet, salty, vibrating environment. It carries an IP66 protection rating, which means it's sealed against heavy dust and strong jets of water from any direction. Spray off the bow, a wet bilge, a console that takes the occasional wave over the rail, the seal holds up. The hardware is stainless steel, so the stud and nut aren't going to rust into a crumbly mess two seasons in. That matters more than it sounds. A corroded terminal is a high-resistance terminal, and high resistance means heat and voltage drop right where you don't want it.
Connection is a No. 10-32 stud terminal. You land your ring terminals on the stud, torque the stainless nut down, and you've got a solid mechanical and electrical joint. Single pole, single circuit, one breaker per protected run. The operating temperature range runs from 40 below zero all the way up to 185 degrees Fahrenheit, so it'll keep working whether you're launching on a frozen ramp in the north or running an engine compartment that bakes in the summer sun down south.
Egis Mobile Electric has been in the electrical protection business for over 25 years, building gear for marine, emergency fleet, and specialty vehicle use. The Short Stop line is their bread and butter for panel-friendly, manual reset protection. If you're rewiring a console, adding a circuit, or replacing a tired old fuse holder with something you can actually reset on the water, this is a straightforward, honest little breaker that does exactly one job and does it well.
One note on sizing. Don't just grab a 10 amp because your device draws 8. Look at the wire feeding the circuit and pick the breaker that protects that wire. If you're unsure, our crew wires boats for a living, so give us a shout and we'll help you get it right.

Frequently asked questions
What does the 10 amp rating on the 4730-10 protect?
It opens the circuit before the wire overheats on a fault or overload. Size the breaker to the wire gauge it protects, not to the device draw. A 10 amp breaker is a common fit for smaller helm loads like nav lights, a VHF radio, a livewell pump, or a stereo feed, as long as the conductor is rated to match.
What is a Type 3 manual reset breaker?
Type 3 means it trips on an overload and stays tripped until you physically press the button to reset it. It won't reset itself. That's what you want on a circuit where a repeat trip signals a real problem, like a chafed wire or a stuck pump, instead of quietly cycling on and off.
Will this work on a 12 volt boat?
Yes. The 4730-10 is rated for 28 volt DC, which is the maximum. That rating covers both 12 volt and 24 volt DC systems, so it drops right into a standard 12 volt marine circuit.
What does the IP66 rating mean for mounting?
IP66 means the breaker is sealed against heavy dust and against strong jets of water from any direction. It's suited for wet locations like an open console, a splash-prone dash, or a bilge area where spray and moisture are part of daily life.
How does the wiring connect?
It uses a No. 10-32 stud terminal. You land ring terminals on the stud and torque the stainless steel nut down for a solid electrical and mechanical joint. It's a single pole breaker, so it protects one circuit.
Is the hardware corrosion resistant?
Yes. The 4730-10 uses stainless steel hardware, which holds up far better than plated steel in salt air and spray. That keeps the terminal connection low-resistance and reliable over multiple seasons.
What is the operating temperature range?
It's rated from -40 degrees Fahrenheit up to 185 degrees Fahrenheit. That covers cold-weather launches and hot engine-compartment installations alike.
How is this different from the other Short Stop amp ratings?
The Short Stop line comes in several amp ratings. This is the 10 amp version, color coded red. The higher amp versions use different colors, which makes it easy to tell them apart when you have several breakers mounted together. Choose the amp rating that protects the wire feeding your circuit.
