The QJW3 series manual self coupling voltage reducing starter is suitable for general industrial AC 50HZ or 60HZ, rated working voltage of 380V, and power of 14KW-115KW three-phase squirrel cage induction motors for voltage reducing starting and stopping. By using an autotransformer for compensation during start-up and installing protective devices such as overload and voltage loss tripping.

model



structural characteristics
The QJW3 (QJ3) manual autotransformer pressure reducing starter consists of a protective shell made of thin steel plate, a starting autotransformer, a contact system (contacts immersed in oil), an operating mechanism, and a protection system. It has overload and voltage loss protection functions.

Technical parameters of QJW3 (QJ3) manual self coupling pressure reducing starter
The starter selects its rated current and starting autotransformer based on the rated working voltage and rated power. The data is shown in the table (except for those with other requirements for rated working current and thermal protection setting current in the table).
