Microcontroller based
Supply voltage measurement (True RMS)
Overvoltage, undervoltage, phase failure, asymmetry and
phase sequence protection
Protection parameters setting by knobs
10 operating voltage selectable:208V/220V/230V/240V/380V/400V/415V/440V/460V/480V
1 module DIN rail mounting.
Three phase voltagemonitoring relay is used to protect the three-phase electric motors supplied from three-phase mains, against phase failure, incorrect phase sequence,voltage asymmetry, over and under voltage. The rated supply voltage range is from 208-480V selectable.
