Answer / Lalita Kumari

A saturation kit is a device used to minimize the torque pulsations and electromagnetic interference (EMI) caused by the switching of motor starters. It is especially important for motors above 15kW as they can produce high levels of harmonics that may cause problems in electrical systems. A typical saturation kit consists of a reactor or inductor connected in series with the motor starter contacts, helping to reduce the inrush current and improve the overall performance and efficiency of the system.
