MIF II - Legacy
Manufacturing for this product has been discontinued. As an alternative, please refer to P14N and 350 relays.
The MIF II, part of the M II Family of economical and highly functional digital relays, provides comprehensive distribution feeder protection and can also be used for backup protection for transformers, busbars, generators and large motors.
In addition to feeder protection, the MIF II also provides integrated breaker control (open/close) and recloser functions.
To complement its protection and control features, the relay's user-friendly controls and plug and play setup software make this product very easy to configure and use.
