NJYB3 Relay
1. General
NJYB3 relay is used to provide overvoltage,
undervoltage, phase failure, phase sequence and three-
phase unbalance control in three-phase three-wire 380V
circuits and three-phase four-wire 220V circuits with a
frequency of AC 50Hz. For example, it is used for power
control systems, air conditioning systems and motors.
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, error-phase or unbalance and controls the
operation accurately and stably by means of the built-in
microprocessor.
