Three-Phase Voltage Monitoring Relays

CHINT NJB1-X and NJB1-X1 Three-Phase Voltage Monitoring Relays.
Function: These relays provide protection for three-phase equipment against phase sequence errors, phase failure (loss), and voltage unbalance.
Voltage Range: The NJB1-X series typically operates in AC control circuits with voltages ranging from AC 380V up to AC 480V.
Application: They are used in industrial settings to protect motors and other three-phase equipment by disconnecting the circuit when a fault is detected.
Features: The devices are DIN-rail mounted and feature indicator lights to show power status and fault conditions.
