    I am the manufacturer. I work at TOSHIBA. See, I think I could not make myself clearly, sorry for that. I remember that I trying to receive some help, not to fight or been “warning” for some reason. Please let it go, Thanks for all. Regards.

    STOP RIGHT THERE……. I am not so desperately to prove anything.... and for sure, if we will export to US, be sure that TOSHIBA will provide the needed equipment according with your requirements ok?. No issues about that. The problem is that, for some disconnector switches, rated to 31,5KA/1s...

    Yes, I think that can be done too, just checking.. Thanks.

    Oh yes, sorry for that. 145KV is the sytem voltage, the 31,5KA is the short circuit withstand current, of course the DS will not OPEN with this current.

    Hi there. I got a disconnector switch with short current rated to 31,5KA/1s, I need to demonstrate that his contact are able to support 31,5kA/3s. Based on type tests recorded earlier, the only information I have are the contact resistance and contact area, can anybody give me a tip if it is...
