LV Breaker time curves calculators

[Dave32]

Hello All. I was wondering if anyone has made some trip unit calculators for fast reference to look up time curves?

I did make a (primitive) calculator for the GE Entelliguard TU on a excel sheet as that is what we Hi-Current test the most of. However, we are starting to see more and more AC-Pro (URC) TU’s coming through our shop. I did download a calculator for the Digitrip programmers some time ago from here (thank you for who made them) that work very well.

Thanks
Dave

The AC Pro manual contains some very unique calculations within the manual which can quickly be thrown into an Excel sheet and spit out results.
