ECN Forum Forums General Topics of the Trade General Discussion Area Adjustable trip/ Inverse time Breakers

What is the difference between these two, and other than motor loads, where do most of you guys use these type breakers?

I recently came across a couple of these adjustable trips in a MDP, that fed subpanels in commercial units, and can't figure out why someone used these in this application.

Thks..
