The Klixon circuit breaker on my windlass has failed. Am having a hard time finding the original part (TI Klixon 6766-19-80 9939, see photos). Does anyone know of any other model that will work as a replacement? Thanks, Roger
Replace Maxwell 500 windlass circuit breaker

I would say to look at the Maxwell 500 specs and see what is required in the way of maximum amperage.
Amps = 600W / 12V = 50A.
See the Maxwell Install manual :

A 60A breaker would be sufficient. Go with a reliable mfg. like Blue Sea.

I'm confused.
If the existing wire was a #4 wire, would it require a different breaker ? Or, if the existing wire was a #8 wire, would it require a different breaker ? At what point would a 60A breaker no longer be acceptable ?
Why would you need a different breaker if the wire is #8 ?Maybe….
#8 yes, #4 no.
In order to get this project on the rails and moving, I gave the OP a copy of the installation manual for the Maxwell 500 which told us the windlass pulls 50A maximum. That was pretty well the end of the story. Deal with a 50A draw. We don't really care what the amperage of the failed breaker was given that info. Don't make it any smaller or you've got nuisance trips. Don't make it too much bigger or you may be endangering the original wiring. My recommendation was 60A. That would have enabled some not too bright individual to safely put in 10AWG wire and the windlass would have barely turned over if at all. BUT everybody's safe.
You're right, we should have ensured the wire was sufficient for 60A but the correct breaker for the Maxwell 500 is a 60A breaker by my calculations.
Mind you, you could go to the Maxwell breaker sizing chart for the 500VC :

The old one was a Klixon 80. Replaced the entire unit with a new one from Catalina Direct. Works great. Too bad they couldn't match the old mounting screw pattern, but, oh, well.
Am I correct in assuming the new E9 80 is an 80A breaker ?
Were you able to determine the size of your wiring to the windlass and does the new breaker have the correct amperage rating ?

The old one was also 80A. Just went with what appears to be a more recent version of the same unit, a recommended replacement: Windlass Breaker Panel 80 Amp
Take care when reading the Catalina Direct page about their breaker. They say it's 135Amp, but the original one on my 2003 boat is a Klixon 6766-19-80 9157, which is 80 amp. I don't think the winch draws more than 50 amps and I don't think you can run 135 amps on a #4 wire.
I replaced mine with a Blue Sea 7042 187 - Series Thermal Circuit Breaker - 80Amp https://www.amazon.com/dp/B08C23Y3MZ?psc=1&ref=ppx_yo2ov_dt_b_product_details

Be careful ordering Blue Sea products on Amazon they are often fakes.

Scary. The one I received seems to be very high quality, though.Be careful ordering Blue Sea products on Amazon they are often fakes.

It is not just Blue Seas. I ordered "Genuine Cannon Ink" for my printer, received some knock off brand. Sent it back. Occasionally I shop at Amazon, but only for things where quality or safety is not a big issue.
