DXJ Type Phase Breaker and Phase Sequence Protection RelayDetailed product description：

Overview:
DXJ phase failure and phase sequence protection relay are the protective gods of electric motors. Compact, sensitive, and reliable. It has a sustainable protective effect on electric motors during phase failure and misalignment, and can be widely used in forming machinery, packaging machinery, and various equipment that requires three-phase motors.

Working principle
This relay samples the voltage from three phases A, B, and C, and determines the balance degree of the three phases through electronic circuits. When any phase in the three phases is disconnected or the phase sequence balance point is broken, the relay loses power and releases, and the indicator light is on. When it is working normally, the relay is activated and the working indicator light is off.
