Can anyone tell me the difference between a standard type one 12 volt circuit breaker and a type one "short stop" 12 volt circuit breaker. I know that a type one is an auto reset. The circuit breaker for the slides on our motorhome failed and when I talked to the Monaco tech. staff they said just put a regular breaker in as they have never heard of a short stop breaker. I also went to several dealers and they also said they never heard of a short stop breaker.

I know that Bussman makes them and I was able to find the one that I need on line (had to buy 4) and have installed it but would like to find out the difference between the too breakers and if it is OK to replace the short stop with a regular circuit breaker. I have left messages with the Bussmen staff but they are not returning my calls.

Type 1 circuit breakers automatically reset - After the circuit breaker trips, it will automatically reset itself, or cycle. If the overlaod or short still exists, the breaker will re-trip.

Type 2 circuit breakers stay tripped until the power source is removed, usually by turning a switch off. Once power is removed, the breaker will reset.

Type 3 circuit breakers will rmain tripped until you manually reset them by pushing a button on the side of the breaker.

I'm guessing: the nomenclature "short stop" refers to time delay for reconnect, i.e. quick reconnect time vs. standard delay?

As far as I know, Short Stop is simply a product trade name for a line of Bussman Fuses. No significance to the name as far as function is concerned. See the Bussman page below for "Short Stop" fuses:

Thanks for the replys. I did get in touch with Bussman Eng. today and they did confirm that the name on the circuit breaker of "Short Stop" is just a trade name and it has all the same values as a regular 25 amp breaker so they are interchangeable with a breaker that you can buy at an auto parts store as long as the breaker meets SAE J553 and SAE J1171.

He did tell me that the difference between the full plastic breakers versus the metal can with a plastic top is that the full plastic is designed to stand up better in a wet location.

Thanks again for the feed back

There is a common product usually called a "Band-Aid".. now it may be made by Johnson & Johnson, 3-M Curad or yet another company but frankly they all do much the same thing.

The fact is Band-Aid is a brand.. (So is Curad) i'm not sure what 3-M calls theirs)

Short Stop.

That is a brand.. Nothing special about it.. It's a brand or to be more precise a model. made by Bussman.

There are several other brand/models that are electrically identical I see someone provided the link up-thread
