    Various shunt trips in a MG M-Pack 1000A ACB.



    Watch out if UV coils are fitted, they get very hot and can burn the skin.
    The reports of my death are greatly exaggerated.

      UV coils?
      Our comedian shamelessly joked about a blackout. Talk about dark humor.

          I think we have wildly different ideas of the scale the OP is talking about.

            The purpose is the same whatever the size of the breaker.

              Nothing like that at with any UV shunts I have worked with and I bet the OP either.

              Looks like you are posting MV switchboard equipment from the 70s.

                  Why would they be run so hot?

                    Ask MG, all I know is I burnt my fingers taking one out of a live breaker.

                        But do they do exactly to get so hot?

                          That must've suck. At least they weren't live though. I've grabbed on to thyristor heat sinks I thought were dead- turns out they were referenced to one side of the DC supply
