Sea-Dog SD-13 Breakers: Screw vs Quick-Connect Terminal Guide

The Sea-Dog SD-13 is a compact push-to-reset thermal circuit breaker for appropriate electrical panels. It is available with #8-32 screw terminals or ¼-inch quick-connect blades and multiple amp ratings. Choose the current rating required by the original protected circuit, then match the installed connection and panel dimensions.

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 check before selecting a replacement

  1. Read the original breaker amp rating. Never substitute a higher setting merely because the existing device opens the circuit.
  2. Inspect the back: screw terminals require different connectors from quarter-inch push-on blades.
  3. 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.
  4. Confirm DC or AC use and the relevant interruption rating for the actual circuit, not voltage alone.
  5. Correct the underlying overcurrent fault before resetting a tripped breaker and restore proper protective covers where specified.
