Product Description

Product Description

 

Model	XJ3-D
Working voltage	AC 380V (50Hz)
Installation method	Rail installation or punching installation

XJ3 series phase failure and phase sequence protection relay, used for overvoltage and undervoltage, phase failure protection, and irreversible protection in three-phase AC circuits

The phase sequence protection in transmission equipment has the characteristics of reliable performance, wide applicability, and convenient use.

This series of protectors can be connected to the power control circuit according to the diagram, which can provide protection. Any phase in the three-phase circuit can melt

When the circuit breaker is open or there is a phase break in the power supply line, XJ3 immediately acts to control the contact to cut off the power supply of the AC contactor coil in the main circuit,

So as to achieve the action of the main contact of the AC contactor and provide phase failure protection for the load.

When the three-phase irreversible equipment is connected to the original recognized phase sequence due to maintenance or modification of the power supply line after confirming the phase sequence,

The XJ3 series can also distinguish reliable phase sequence operation, stop supplying power to the power supply circuit, and achieve the purpose of protecting equipment.
