GE SFLA Circuit breakers

Just wondering if anyone has come across this before.
We installed a 300A 277/480V, 3-phase, 4W service in a building in
2000. The distribuition section is a GE Spectra series board.
In this boad, we have several circuit breakers among which are 200A
SFLA C/B's. (250A frame w/ 200A trip unit)
These breakers feed various panels and transformers with the highest
load being 160A for a panel feeding battery chargers.
(10) of these 200A SFLA c/b's have what looks like burning or
corrosion arount the trip rest button and the trip unit.
We are trying to find out what could be causing this.
The other c/b's in the board are fine (both larger and smaller Amp
c/b's)
I found an alert regarding GE c/b's and trip units online, but this
alert does not appear to cover this type of breaker and the time
period in question.
Does anyone have ideas as to the possible cause or a good source where
any reported problems might be posted?
I checked the GE site for any info without any success.
Thank You for any input.

Probably the best immediate path is to contact the GE distributor who sold the breakers and ask for a field service observation. Theat you have ten breakers with a similar problem might speed response. They should ask you to replace one of the breakers and send the removed one for testing.
GE seems to have a lot of breaker problems.

We took digital pics and sent them along to GE. Hopefully they will send a rep out without too much phone tag. Pictures of the bussing and breaker connections clearly show everything is fine (No discoloration whatsoever). I was just wondering if anyone has seen/heard of this type of thing before. Thanks for the response, I'll post the results when this gets worked out.

yes, I have but not with GE.
I would calling the folks that I purchaced them from. I would be asking for new product including installation/down time. I know all of the OEM's terms of sale are parts only. I have seen SQD and CH both install defective equipment free of charge and offer an extended warranty.
Force the seller to do his job. If your any sized customer at all. the seller can get GE engineering services out there asap. GE does have someone in almost every major market.
SCREAM loudly and often. Call the GE sales group locally and demand help. The sales office can handle the problem in a twinkling of an eye, if they are prompted. Stop or put on hold all GE purchaces. Let the sales guys know why.
I worked for an OEM as a feild engineer for quite awhile. I was once sent to New Mexico from AZ to fix some breakers for a OEM manufacture. I got to BumF--K New Mexico during the second day of traveling. The customer, had shipped the breakers in the intermediate position instead of out of the cells or latched against the bus. The part that broke was a 1/4-20 bolt of a special design. The whole thing was taken care by warrantee even though the equipment was 10 years old and it was the customers fault. I had two days of wandering around fishing and taking pictures. Where I was FEDEX over night was 2-3 days.
