Sea-Dog 830111
5A push-reset thermal breaker with #8-32 screw terminals.
Identify Sea-Dog SD-13 Marine Breakers by Amps & Terminals
Sea-Dog SD-13 breakers look similar from the front: each has a white push-reset button and a compact panel body. The rear electrical connection makes an important difference. The 830111–830118 group uses screw terminals, while 830150–830155 here uses quarter-inch quick-connect blades. The amp rating must match the protected circuit.

| Sea-Dog MPN | Amps | Connection | Reset | DC limit |
|---|---|---|---|---|
| 830111 | 5A | #8-32 screw terminals | Push-reset | 50V DC |
| 830112 | 7A | #8-32 screw terminals | Push-reset | 50V DC |
| 830113 | 10A | #8-32 screw terminals | Push-reset | 50V DC |
| 830114 | 15A | #8-32 screw terminals | Push-reset | 50V DC |
| 830115 | 20A | #8-32 screw terminals | Push-reset | 50V DC |
| 830116 | 25A | #8-32 screw terminals | Push-reset | 50V DC |
| 830117 | 30A | #8-32 screw terminals | Push-reset | 50V DC |
| 830118 | 40A | #8-32 screw terminals | Push-reset | 50V DC |
| 830150 | 3A | ¼-in quick-connect blades | Push-reset | 50V DC |
| 830151 | 5A | ¼-in quick-connect blades | Push-reset | 50V DC |
| 830152 | 7A | ¼-in quick-connect blades | Push-reset | 50V DC |
| 830153 | 10A | ¼-in quick-connect blades | Push-reset | 50V DC |
| 830154 | 15A | ¼-in quick-connect blades | Push-reset | 50V DC |
| 830155 | 20A | ¼-in quick-connect blades | Push-reset | 50V DC |
Important fit distinction: A breaker with the same amp rating but a different terminal type is not an automatic plug-in replacement. Sea-Dog uses #8-32 screws on 830111–830118 and ¼-inch blade terminals on 830150–830155. The SD-13 maximum ratings are 250V AC or 50V DC, but suitability for a particular marine or RV AC branch circuit must be established by the electrical design. Never increase the breaker rating to stop nuisance trips.
Shared case reference: Sea-Dog lists body drawing dimensions A = 1⅜ inches, B = 7/16 inch, C = 1¼ inches and D = 9/16 inch, with a 3/16-inch panel-depth reference. The exact measurement positions are shown in the manufacturer diagram. The optional 830901 breaker boot is a separate accessory and is not included in these product cards.
Manufacturer dimension and specification references: quick-connect, screw-terminal. These include the original switch and breaker drawings.
What to inspect before replacement
- Read the original breaker amp rating. Never substitute a higher setting merely because the existing device opens the circuit.
- Inspect the back: screw terminals require different connectors from quarter-inch push-on blades.
- Confirm available rear-panel space and the original opening using the manufacturer's diagram; the listed 3/16-inch panel-depth reference is not a generic cutout diameter.
- Confirm DC or AC use and the relevant interruption rating for the actual circuit, not voltage alone.
- Correct the underlying overcurrent fault before resetting a tripped breaker and restore proper protective covers where specified.
