General
GKRC type over and under / over voltage monitoring relays aredesigned to protect single phase or three phase systems fromvoltage variations and phase sequence failure.
.
Note: These relays include the feature of switching OFF
immediately if any of the phases exceeds (or reduces from)
the nominal voltage by 50%
