NJYB3 Chint phase failure relay

NJYB3 Chint Phase Failure Relay NJYB3-8-AC380V

NJYB3 Relay is used 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 operation accurately and stably using the built-in microprocessor.
