Redtrumpet,
Thanks.
I guess that I am used to seeing transformer secondary design voltages of 480V and motor nameplate design voltage of 460V.
I support two plants in Canada. All the low voltage substation transformers have their secondary winding design voltages as 575V. And all the motors...
Well, I found my answer.
The K-line of breakers have the following interrupting rating.
240Vac: 65kA
480Vac: 50kA
600Vac: 42kA (also know as 575V in Canada:)
The S in K-1600S means that the trip unit was retrofitted with a static trip unit, also known as solid state trip unit.
Ain't...
Kunderd, Thanks for the sites, but you are right in that the info I'm looking for would require effort from them for no return.
jbartos, that website has some Molded Case Ckt Bkr info, but no old info on Low Voltage Power Ckr Bkrs. That is what I dislike about the Siemens website, not being...
Hello All,
I am trying to find the interrupting rating for the ITE/BBC family of K-Line breakers. In particular, I have 8 K-1600S breakers and one K-1600 breaker.
A web-site showing the ratings would be best. I believe Siemens now owns that family of breakers, but their web-site is horrible...
