XJ3-G : Phase Break and Phase Sequence Protection Relay

XJ3 series phase failure and phase sequence protection relays are used for overvoltage, phase failure protection and 

Phase sequence protection in irreversible transmission equipment has the char acteristics of reliable performance, wide application range and convenient use. point. 

This series of protectors is connected to the power control circuit according to the figure, which can not only play a protective role, but also protect any 

When the one–phase fuse is open or the power supply line has a phase failure, XJ3 will act immediately, and the control contact will cut off the AC connecti on of the circuit. 

Contactor coil power supply, so as to achieve AC contactor contact action, and protect the load from phase failure.
