Engineering360: "First digital circuit breaker certified for commercial use"

So, now, hackers (foreign and/or domestic) can more easily "shut-down" everybody's power over the internet?

Also the internet connection could be used by the utility to carry out load shedding or integrate tone control over the supply to load shed as they now do with off peak water heating.

I agree keeping hackers out will be interesting considering that UNI investigation into shutting cars down has been proved.

In the past, electronic switching devices have had problems with

• Off-state leakage resulting in no-load voltages on the load terminals,
• Need for fuses or conventional circuit breakers to provide protection in high short-circuit current applications, and
• Limited application in equipment with high short-circuit current availability (such as 65kA or higher).

I am curious regarding the application instructions, in addition to the marketing hyperbole.
