Hi everyone,
I’m an electrical engineer and I’ve spent the last few month working on a side project. I got tired of comparing time-current characteristics by holding two datasheets next to each other. Different scales, different units, impossible to compare directly.
So, I built "selectivitytool.com".
You can pick up to four protective devices from different manufacturers, and the tool plots all their time-current trip curves in a single interactive log-log diagram, including tolerance bands.
Right now the database has about 23 devices (E-T-A, Schrack, ABB: fuses and MCBs). I'm adding more every week.
Would love feedback from anyone who deals with selectivity in their daily work. What manufacturers or device types should I prioritize?
Thanks for checking it out!
