Like the title says, I am searching for the time current curve for a Siemens QR23B150 molded case circuit breaker. The only one they have on their site, or anywhere else, that I can find, is for a 200A breaker. I need the 150A curve. Any help would be greatly appreciated.

I’ve looked in my records, where I work we also have that product on site, but no TCC’s provided in our shop drawings as well
If you have a local Siemens representative contact information, reach out to them to provide you that information and fix the website link for the product datasheet that provides an error.
