GE MIV II – Legacy
Manufacturing for this product has been discontinued. As an alternative, please refer to the P94V and 350 relays.
The MIV II, a member of the M II Family of Relays, is a digital device that provides voltage and frequency protection for a wide range of applications at any voltage level.
The MIV II can be ordered with one of the following options:
Four independent time delay phase under/overvoltage elements complete with two independent fixed time ground overvoltage elements
Four units of frequency protection
Both voltage protection and two elements of frequency protection
Use the MIV II also to protect electrical machines like transformers, generators or motors against restricted earth faults.
