ETAP Software (Magnetic Contactor Interrupting Rating)

Good luck here, since you did not get what you wanted on the other post. i am also eager to learn more about software solutions to what was only possible by testing in high-power labs at great expense of money, time and other resources.

i am, at the age of 66 years, understandably skeptical. If one could design software that could predict arc-quenching behaviour of circuit breakers reliably, why would we need all those expensive test stations, and the cost and time that needs to be devoted to that ?

i am not speaking in air. i was in the task force to develop such a software for GE in the period 1998-2001. Did my bit to develop the database to back that software. However, GE have not published that software, which should tell you something.

ETAP is, of course, a well-respected software. i am very, very interested in understanding how it considers the Conatctor's max current capacity wrt the current-limiting ability of the MCCB/Fuse that is going to clear the SC before the contactor even knows that there is a SC.

Good Luck.

Furnas , or Crouse hinds , or for that matter look it up in your code book. it should have the information you are seeking.
