I have a facility with several older panelboards manufactured by Trumbull. The circuit breakers are of the ATB type which is not in the SKM library. So far I've been unsuccessful in locating much information online for them. Has anyone encountered these before? If so, do you have a comparable breaker that you used to model the circuit?

Put in a support ticket with SKM and they will send you the CAPTOR library files if they have them.

If you can find the TCC curves send those to SKM and they will create the library file for you.

This suggests Trumball is GE. I'm not at my computer right now and am too lazy to get off the couch to see if there is a GE ATB breaker in the SKM library
