Background we retrofited a bunch of our 480 volt draw out breakers with AC Pros microcontroller solid state trip units. We are currently having to replace them as they arbitrarily change their trip settings (software version 5.1). Luckily for us the trip setting defaulted to a lower setting causing a unwanted trip. My questions to the forum are
What do you think of microprocessor trip devices?
Any one else experiencing problems with the AC Pros?
What trip device would you use in facility?
