Motor running & motor starting capacitors are designed for obtaining an auxiliary phase in single-phase and three-phase motors connected to a single phase.
KNM 12xx, 22xx and 32xx – they are used for obtaining an auxiliary phase in single-phase motors and in three-phase motors connected to a single-phase.They can be used also for other purposes, such as in industrial electronics in electronics circuits where capacitors are lower pulse loaded (Class P0).
