MIN II - Legacy Manufacturing for this product has been discontinued. As an alternative, please refer to the Multilin 350.
The MIN II, a member of the M II family
of protection relays, is a microprocessor
based relay that provides ground
directional protection on distributed
networks at any voltage level and
backup/auxiliary ground directional
protection for transformers, generators
and motors. Additionally, it can be used to
create a separate directional comparison
ground scheme in pilot channels used for
distance relaying.
