NJYB3 Relay

CHINT NJYB3 Relay Specifications

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 opration accurately and stably by means of the built-in microprocessor.
