The importance of trip-free operation and its characteristics
... Any of these variants of “Trip-Free” operation may include a “Trip-Free Relay,” in which its operation alters a closing release circuit, permitting an opening release to operate unimpeded by a closing release operation in any state. For IEC rated products, although the standard recommends that the s ...
