answer
The neutral point color of the capacitor is light blue.
Three-phase electricity is two fires, one zero, one ground, generally red and green for the fire line, blue for the zero line, yellow for the ground line.
Three-phase electricity is short for three-phase alternating current, which is a form of electrical energy transmission. The phase color of three-phase electricity is specified: phase A is yellow, phase B is green, phase C is red, and the neutral line (that is, the zero line) is light blue.
Capacitance. That red dot is the unit that identifies capacitance. Chip capacitors are divided into high-frequency chip capacitors and low-frequency chip capacitors.
