The RNPP-311M voltage monitoring relay is designed for protection of three-phase loads against major types of main faults.

RMS voltage reaching beyond admissible thresolds
phase sequence order violation and phase coincidence
violation of the mains voltage phase completness and symmetry
The device performs monitoring main circuit parameters and de-energizes load when the parameters fall beyond specified boundaries. The front panel LEDs display following:

presence of voltage in the mains
load status
type fault
Adjustment potentiometers allow setting:

tripping thresold for the minimum/the maximum voltage
time delay for load re-energizing after circuit parameters recovery
tripping time delay for load de-energizing in case of all circuit voltage faults
With switches on the device's front panel user can select the type of circuit monitored 380V / 400V and turn on/off monitoring of the following circuit paremeters:

phase sequence and phase coincidence
mains voltage phase completeness and symmetry
voltage drop
voltage surge
Corresponding combinations of the RNPP-311M switches allow for functioning in various modes:

mode of circuit voltage comprehensive monitoring
minimum/the maximum voltage monitoring mode
phase presence monitoring mode
phase sequence violation and phase coincidence monitoring mode
phase imbalance monitoring mode
The phase availability monitoring function is maintained in any position of the switches, including OFF position. The feature of 24V online power supply is available (optional, to be ordered separately)
