Looking for Data on Old GE Breaker - FH-203

[dpc]

I'm looking for any available interrupting and momentary ratings for some (very) old GE oil circuit breakers.

Data I have:

Type FH-203, 1200A, 7.5 kV

TIA

I think that is a 1930's vintage device. Probably better to figure out how to replace it.

If your GE guy can't help, you might try

I recently came across some GE FK frame 15kV breakers still in service that I think are fairly similar. Nobody was quite sure when they had last been operated (much less tested!)

Dave:

In Conrad St. Pierre's Book A Practical Guide to Short-Circuit Calculations they show the ratings of a few FK and FH breakers.

The FH-breaker information they show are for the:

FHK0339-1000
FHK0-136-1328
FH-126-1000
FH-126-1500
FH23

The FH23 seems to be the nearest related to the FH-203 (Rated max kV of 8.25kV) I can provide the data if you are interested.

Regards
Ralph

Thanks, Ralph - that was the first place I looked as well. I don't think it's listed.

I may check with Conrad directly, or GE as a last resort.

I suspect these breakers were installed in the 1920s. But these are routinely operated and tested. These folks don't like to give up on equipment just because it has a little age on it .

Sorry I could not have been of more help.

From "A Practical Guide to Short-Circuit Calculations:"
Much of the information used in Tables 1-1 to 1-13 was developed and used in GE software manual SCT for equipment evaluation....
You might just be lucky to find some info from Conrad St. Pierre (in my opinion the best bet) or maybe from GE.
