GE Model 11 Gas Detector Relay

Hi All,

I have a GE Model 11 Gas Detector Relay (1983 vintage) I tried some information and contacted GE Power technical support, I could not get any information.

I tried to Google to get info from the website no luck. All the information it comes is ABB Model 11 Gas Detector Relay. Does anyone know if the GE-Model 11 is the same as the ABB Model-11. (Is ABB bought this Model-11 from GE??)

The problem we have is that when we tried to put a pressure in the test valve, some oil leaks out through the test valve. The pressure changed the state and send the signal to trip the upstream breaker, luckily we disconnected the FT switches to the relay.

I do not know the construction of this relay to figure out how the oil get into the relay? Any advice how to rectify this problem?

Thanks,
