CHINT NJYB3 Relay provide overvoltage undervoltage

CHINT NJYB3 Relay provide overvoltage undervoltage,
NJYB3 Relay is use to provide overvoltage,undervoltage, phase failure,phase sequence,
three-phase unbalance,PTC temperature and load protection control in three-phase three-wire,
up to 415V circuits and three-phase four-wire up to 240V circuits with a frequency of AC50Hz.
This relay is a voltage protection relay.After detecting the voltage signal,the relay processes the input signal,judges if there is an overvoltage,
undervoltage,phase failure,phase sequence,three-phase unbalance,
PTC temperature and load error and controls the opration accurately and stably by means of the built-in microprocessor.
