## Circuit Breakers

## from the

## Sailnet Tayana List

The other weekend project involved replacing the Stotz-Kontakt breakers (green push in, red release) with modern (and functional) breakers. A friend machined two very simple breaker panels and after spending a few hours to complete an electrical 'plan' for the boat, we installed the properly rated breakers in the new panels, mounted the panes right on top of the existing Tayana panel (using contact cement and screws) and reconnected the wires we had carefully marked from the old panel.

I had no luck finding original Stotz-Kontakt breakers but I now have a healthy supply in case anyone is interested in spares/replacements. I have no idea what they're worth. Contact me off list if you're interested.

Anyone know where to find the Mitsubishi breakers for the AC side? Specifically, I need a 30A to replace an existing 50A.

Jim, I have an 84 V42 and have replaced some 110 breakers. The originals were made by Mitsubishi, were big and black. An original was replaced thru another subscriber on Sailnet, and the yard here has a supply of a different brand from a dealer in NC. If you want I'll ask for the dealer name...

I saw in the latest TOG that you needed info on the circuit breakers with the green push button. These breakers are made by ABB. The US contact is Jeff Haynes email (jeff.haynes@us.abb.com) phone (1-888-385-1221). The ABB part number for a 20-amp breaker is S91-B20 S2. When you contact Jeff he can give you the number of your local distributor. These items are a special order and are fairly expensive ($45 each). Good Luck

I have been from Jeff Haynes to ABB Germany, to ABB Singapore and was informed that they no longer make the S91-B-S2, that they have discarded the worn out tooling used to make these breakers. If you know differently please let me know.

Thanks, Jim January 2001

Hi All,

This is my first posting. I think this a great site with excellent information and opinions. Some personal details follow at the end.

About 3 weeks ago there were some postings related to Circuit Breakers (Joe Ghiotti and Roger Morgan and others). I have successfully repaired several breakers with two different fault types.

1. Breaker is slow/difficult to set especially in cold weather. Fixed by adding a very small amount of lubricant to the spring on the "set lever".

2. Breaker does not set. Fault: Broken wire spindle holding the set button (green). Repaired by replacing the spindle with some welding rod honed to the right dia. (2.5 mm). I have some photos and I can provide a more detailed description.

I thought longer on the original comment. Is your power connection on the pier GFI? My understanding is that a lot of chargers will not work with a GFI, Statpower is one of them. I also have a galvanic isolator. However, piers in our marina do not have GFI. I did run across the GFI problem in the yard. Blew the breaker in a New York minute.

Nicholas,
The circuit breakers are "Stotz Kontakt S901-G 12-24 VDC". Can you give me the number to Minnie's, I cannot find them when I do a internet search. On the autopilot side, from what you are saying the short linear drive 2 model is more than enough to handle your V-42, is that correct?

Thanks for the help,

They are actually made by ABB. A few years back I made contact with their Head Quarters in Germany. The put me in contact with their main US Office. They did some checking and ventually determined that these were no longer available. At some point I was put in touch with an office in Singapore but they never returned the e-mail.

Good luck! I hope you find some. I could use one.
