What Is a 3 Phase Compressor?

The three-phase built-in thermal protector is a star overcurrent protector. The shape is a circular connector, which is fixed on the compressor stator core. When the compressor is overcurrent, the star point is disconnected to stop the compressor. . Normally, the three connectors are connected. If they are not connected, they are damaged. The internal protection can only be measured after the compressor is cut. If the coil winding of the compressor is measured to be conductive, the protector is normal. ^[1]
