Breaker information

Discussion in 'General Discussion' started by Noah, Apr 15, 2008.

    I wonder if anyone here can give me a hand. I am doing arc flash study for an old industrial project. There is one GE breaker I really couldn't find the information for its trip unit. The info I have is: GE air circuit breaker, AK-1-25, 600A frame. The trip unit is GE EC2, 175L376G-2. I don't know if any of you may know this based on your experience. I tried to search it from the website but unfortunately there is no result. If you can help, I will very appreciate it! (as I know, it is not an electronic trip unit)

    Ge Ak-25

    Noah,

    What exactly do you need to know? Are you looking for the device TCC to manually determine the trip time? What software are you using to do your study?

    I am using PTW32 from SKM. Yes,what I am looking for is the device TCC. I couldn't find the information for this device. Could you help?

    The TCCs are available online. Google: GES-6010 , GES-6011 , and GES-6012. These are the TCC numbers for the three different long time pick up bands. This is something the software company would do for you (I would think). The GE / EC-2 is an available trip unit in my software library already. Good luck.
