Can someone ID these old (60's era) breakers?

I would like to know if someone can identify these old breakers (brand, type etc.)
Also, is this type totally obsolete or could I swap modern ones in the same box? (i.e., avoid having to install new panel).

60 amp Zinsco? Pull the panel cover and see if there is a sticker? Do the breakers look like this:

As Ray2047 noted, they look like Zinsco breakers. If they are, you can buy replacements, and rebuilt ones, but they are much higher cost than GE, SquareD, Cutler Hammer, etc. Home Depots, here in Colorado, usually carry some.

They're zinsco breakers. You're best to replace these.

They look a lot like Sylvania/Zinsco breakers; the fact that you are in California supports this as they were mostly installed in the West. You can get rebuilt breakers and replacement breakers, however this design is known to have significant safety problems compared to other brands of similar age. I personally always recommend complete replacement of a Zinsco panel when I encounter one.

Here is a site with a lot of information about this brand: Failure Mechanisms for Zinsco or Zinsco-Sylvania Electric Panels and Circuit Breakers & Zinsco failure photographs

One other problem may be getting them out. Some boxes I have seen had what seemed to be a non removable bar holding them in.

Thanks all. I will take the cover off and see what I've got.

Since we are guessing, I don't think they are Zinsco breakers. I'd guess Bryant. Please let us know once you find out for sure what they are.

But that's a zinsco style handle tie. Plus, bryant used orange for their 60A handles , not 20A.

You might be right, but I don't think the handles themselves look like Zinsco handles. We'll see when the OP comes back with more information.

I thought the same thing Joe -- the handle doesn't quite look Zinsco so I'm thinking one of the Zinsco variations like Sylvania or GTE.

And hence my question mark in my reply. Both the cover and color (orange?) was a bit off for the 60a panel I had.

The main thing here though (IMHO) is that that is a 60a panel so regardless of brand probably needs replacement with a larger service.

Coincidentally, I happened to see a drawerful of Zinsco breakers today, some old and some newer. There were several still in original packaging too. I think I'll retract my earlier opinion now. The pictures now appear to me to be older Zinsco breakers. I don't really think you can go by the colored handles, colors and handles shapes seem to have changed some over the years and at one point they were all black before they went back to colored handles again in the later years. The handles in Ray's picture in post #2 is a more recent handle design. The handles on the breakers in question are an older design.

I hope that tobar returns with more information. My immediate thought was also Zinsco and then I thought maybe not based on the shape pf the handle. Since it has been some forty years since I had anything to do with a Zinsco panel I thought it best to not reply.

Observation....

Zinsco has horizontal panel with vertical throw colored breakers ???

The Murry, and Bryants and others were vertical with horizontal throw??

Catalog

I would say Zinsco, plus the OP is in Cali.....

We don't know if the picture posted is the same orientation as the installed panel.
