You can buy the Chint NJYB3-4 Voltage Monitoring Relay online at Roshanex in Pakistan.

OVERVIEW:

• NJYB3 relay is used to provide overvoltage, undervoltage, phase failure, phase sequence and threephase 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

Features:

• Used to protect and monitor voltage errors of 1-phase, 3-phase and 3-phase 4-wire circuits including: phase loss, phase reversal, phase difference, over voltage, low voltage.
• Using voltage protection  in   industrial electrical systems, construction and civil.
• Use 1pha and 3 phase motor protectio.
